This time’s theme is “What cause vision loss?”

Human’s eye catches an information from outside and send it to brain.
Light passes through transparent parts of the eye such as cornea and crystalline, then light hits the retina. Cells called photoreceptors turn the light into electrical signals. The information of the image passes through optic nerves and brain turns the signals into the images.
Is there something disturbing these processes? What causes vision loss?

・Vision loss by myopia, hyperopia, and astigmatism.
myopia, hyperopia, and astigmatism could be the cause of vision loss. Focus point on the retina would be inappropriate by these reflection errors. It causes blurry vision.
In generally terms of “vision loss” means reflective problem. Correction by eyeglasses and contact lens would help to improve the vision.

・Vision loss by an opacity in clear parts of the eye
An image is through transparent parts of an eye such as “Cornea, aqueous humor, crystalline, and vitreous.” If there is an opacity on the clear parts of the eye, visual acuity would be worse.

①　Disease that cause a loss of corneal transparency
Corneal ulcer, Corneal opacity or other corneal diseases.

②　Disease that cause a transparency loss of aqueous humor
Hyphema (bleeding in anterior chamber)

③　Diseases that cause a transparency loss of a crystalline.
Cataract

④　Diseases that cause a transparency loss of vitreous.
Vitreous Hemorrhage, Vitreous opacity

・Vision loss by retinal or central fovea disease.
Retina is like a film of a camera. To see clearly, it is important that an image is casted on the retina appropriately.
A central fovea on a macular is especially important for clear vision. If it gets swollen, it called as “macular edema”, and if there is a membrane over the macular, it called as “epi-macular membrane”. These diseases will cause vision loss.

・Diseases that cause abnormality on a central fovea.
Macular degeneration, Epi-macular membrane, Central retinopathy

・Diseases that cause abnormality on a retina.
(If central fovea is suffered from these, these would cause vision loss.)
Retinal detachment, Diabetic retinopathy

・Related to optic nerve diseases
An image casted on a retina is through an optic nerve to a brain. If there is abnormality on the optic nerve, vision will be influenced.
Exp.: Optic neuritis, Advanced glaucoma

・Related to brain diseases
Visual field defect is a distinctive symptom of brain diseases. If a doctor diagnosed that the symptom is related to brain diseases after examinations and consultations, he/she will write a referral letter for neurosurgeon to further examination and treatment.

At our clinic, a staff member would ask about your symptoms specifically, then perform examinations.
There could be many diseases affect your vision.
If you find blurry vision or vision loss, it is important to consult with ophthalmologist as early as possible.

Today’s topic is “Is glaucoma hereditary?”

Glaucoma is a disease in which the optic nerve is damaged for some reason, causing a defect in the visual field (area of vision). One of the causes is hereditary glaucoma. Having a family member or relative with glaucoma does not necessarily mean that everyone will develop glaucoma. They are more likely to develop glaucoma than those who do not. It has long been known that some cases are familial in origin and are considered a multifactorial and polygenic disease involving both genetic and environmental factors.

◆Congenital glaucoma
It is seen mainly in infancy.
It occurs when there is a congenital abnormality in the eye structure.
▪Causes
Congenital glaucoma is caused by congenital underdevelopment of a region called the corner angle, which is important in regulating intraocular pressure. The cause is not known for certain, but it can occur as a symptom of a genetic abnormality or congenital disease.
▪Symptoms
Symptoms due to congenital glaucoma are identified after birth or in infants. The eyeballs of newborns are soft, and glaucoma causes the eyeballs to enlarge as a result of high intraocular pressure.
Other symptoms may include the following:
・The black eye area appears to be larger.
・Lots of tears.
・Be sensitive to light.
・Cloudy white in the black eye area.
These symptoms are indicative of elevated intraocular pressure.
If congenital glaucoma is left untreated, the optic nerve is damaged over time due to high intraocular pressure.
Damage to the optic nerve can lead to blindness because the optic nerve is so important in the formation of vision.
▪Medical treatment
Congenital glaucoma is treated as soon as it is diagnosed. It is important to receive early medical attention and regular follow-up after treatment to protect your vision.

Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is at an advanced stage.
Because vision loss due to glaucoma can't be recovered, it's important to have regular eye exams that include measurements of your eye pressure so a diagnosis can be made in its early stages and treated appropriately. If glaucoma is recognized early, vision loss can be slowed or prevented.

Today’s topic is “Eye exams for children”.

A newborn’s vision is mostly blurry, but the visual system develops over time and is fully formed in the teen years. As children grow, their eyes change quickly.
The sooner any eye problem is found, the sooner you and your child will be able to get any treatment and support needed.

Children may not realize they have a vision problem so, without routine tests, there's a risk a problem may not be spotted. This may affect their development and education.

A number of tests may be carried out to check for vision or eye problems in babies and children.

・Refraction test
A refraction test is used to check if your child needs glasses and, if so, what prescription they need.
Before the test, your child may be given special eyedrops that widen their pupils so the back of their eyes can be examined more clearly. Your child will be asked to look at a light, or read letters on a chart if they're old enough, while different lenses are placed in front of their eyes.

・Random dot stereo butterfly
A goal of vision screening is the detection of amblyopia risk factors, including strabismus. The random dot Stereo Butterfly test requires no instruction, has a simple pass/fail response with no monocular clues, and is easily administered.

・Prism bar
The prism cover test has been in use for many years for measuring ocular alignment. The measurements obtained are used for both calculating the amount of correction needed in strabismus surgery, and monitoring any change in ocular alignment with recovery from muscle imbalance.

What is FDT perimetry?
FDT perimetry (Frequency Doubling Technology) is a technology that examines the sensitivity of a particular population of retinal neuronal cells, called type "My" (representing 3.5% of the total retinal nerve cell). These cells are the first cells to suffer and lose their function in the event of damage from glaucoma.

What is the purpose of FDT perimetry?
It is used to evaluate any alterations or deficit in the normal field of vision caused by certain eye diseases, including glaucoma. It is usually required for patients with suspected glaucoma who’ve had normal results of the conventional visual field examination.

How is the exam performed?
The patient sits in a chair and rests his head on a machine. The patient is blindfolded on the left eye and given a remote control to press every time he/she sees a grid projected on the screen of the machine (a set of black and white bars, projected in a certain portion of your field of vision). It is important that the patient moves a black dot along the screen of the machine to facilitate the examination and make it more reliable by cooperating. After examining the right eye, you proceed the same way with the left eye. The test result is ready in minutes.

Which patients can undergo the exam?
All patients can undergo this exam: it is quick and easier than the conventional visual field examination.

Is FDT perimetry painful or dangerous?
The exam is painless and not dangerous.

What is a laser treatment?
A laser, as it is called electromagnetic wave, is an intense, focused beam of light that can heat and destroy human tissue. It has been used for not only the treatment of ophthalmic diseases but also in many fields such as telecommunications, appliances, etc. The use of laser in ophthalmic diseases is known as laser photocoagulation or laser photoablation. It has been used since 1960’s in an ophthalmology field, and it is a common way to be done today. There are some types of laser treatments, and which type of treatments is applied to depends on individual cases.

Types of laser treatments.
Retinal laser photocoagulation
It is a way to treat some ophthalmic diseases such as retinal tear, diabetic retinopathy, etc. This can slow down the progress of diseases with applying carefully selected laser wavelength to diseased retina and coagulating involved area. The purpose of this treatment is to control the development of them, not to make a complete recovery.
*Ophthalmic diseases that are mainly applied to this treatment are as follows:
diabetic retinopathy, retinal vein occlusion, central serous chorioretinopathy, retinal tear, retinal detachment, age-related macular degeneration, etc.

Iridial laser photocoagulation
This treatment is performed if you have a risk of being taken with an attack due to narrow-angle glaucoma or angle-closure glaucoma. This applies a laser beam to around your iris and make a hole there to prevent rapid increase in the degree of your eye pressure. The treatment is done if the degree of your eye pressure does not go down as planned with eyedrops or it is likely to develop visual field impairment.
*Ophthalmic diseases that are mainly applied to this treatment are as follows:
glaucoma, open-angle glaucoma, angle-closure glaucoma, etc.

YAG laser capsulotomy
This treatment is mainly performed when you develop secondary cataract that makes your crystalline lens clouded after cataract surgery. In this way, a laser beam is used to make a small hole in the clouded capsule to provide a clear path that the light can pass through.
*Ophthalmic diseases that are mainly applied to this treatment are as follows:
secondary cataract.

SLT
SLT stands for Selective Laser Trabeculoplasty and is one of treatments for open-angle glaucoma.
Inside your eyeballs are filled with liquid called aqueous humor. It is constantly produced from your ciliary body and released through trabecular meshwork so that the degree of eye pressure remains stable. However, if the function to release it does not work well for some reason (ex. Stacked trabecular meshwork), and then aqueous humor stands inside your eyeballs, resulting in the eye pressure elevation or the progress of glaucoma.
SLT is a treatment way to decrease the degree of eye pressure with applying laser wavelength to pigment cells that block flow of aqueous humor in trabecular meshwork.
It requires no hospitalization and is suitable way for pregnant women or someone who concerns side effects with eyedrops, tends to forget to apply them or is reluctant to do so.

Retinal laser photocoagulation, YAG laser capsulotomy or SLT are performed in our clinic.

Corneal disease

Corneal disease is a serious condition that can cause clouding, distortion, scarring, and eventually blindness. The term "corneal disease" refers to a variety of conditions that affect mainly the cornea. There are many types of corneal disease. The main types of corneal disease are injuries, allergies, keratitis, dry eye and corneal dystrophies.

Corneal Erosion
A corneal erosion occurs when there is loss of the corneal epithelium, the cornea’s outer layer. These can occur if your corneal is scraped or injured, often leading to eye pain like there is something in your eye, eye redness, light sensitivity, blurred vision, and tearing. A cornel erosion typically heals quickly, an antibiotic will be effective for preventing infection.

Corneal herpes
It usually occurs when a previous infection with the virus reactivates and spreads to the eye. It also can happen randomly or maybe triggered by an illness or a high temperature, stress or an eye injury. Symptoms of corneal herpes include a red eye, eye pain, sensitivity to bright light, a watering eye and blurred vison. Make sure to follow the advice and take any prescribed treatment. It’s important to complete the recommended course of any medicine even if your symptoms go away. This will help stop the virus coming back. If it’s not treated, there’s chance your vision could be affected.

Keratoconus
Keratoconus occurs when your cornea thins and gradually bulges outward into a cone shape. A cone-shaped cornea causes blurred vision and may cause sensitivity to light and glare. Keratoconus usually affects both eyes, though if often affects one eye more than the other. It generally begins to affect people between the ages of 10 and 25. The condition may progress slowly for 10 years or longer.

Dry eye
In this condition, the eye is not able to keep its surface moist and lubricated and produces lower quality or quantity of tears. Dry eye causes scratchy feeling including other symptoms like burning in the eye, stinging, episodes of excess tearing followed by dryness, pain and redness. It can also lead to eye surface infections. For most people with occasional or mild dry eye symptoms, it’s enough to regularly use eye drops such as artificial tears. Or if the symptoms are persistent and more serious, trying punctal plugs may be effective. It plugs the openings to the tear ducts with tiny silicone plugs. These plugs close the tiny opening that you have in the inner corner of your upper and lower eyelids. The closure conserves both your own tears and artificial tears you may have added.

“Side effects of eye drops”.

Side effect means that an undesirable effect caused medical treatment.
Eye drops sometimes have side effects written below.

・Burning, sting sensation
Eyedrops may cause burning, sting sensation as side effects. There are many causes. For instance, corneal damage caused by dry eye, and allergic inflammation caused by some components of eye drop.
Average PH of human tear is generally 7.0 ~ 7.4. If the PH level of eyedrop the further away from the PH level of tear, the more irritating sensation caused by eye drops.

・Red eye
Eye drops may also get your eyes red. If eyedrops don’t work well, irritating sensation and pink eye might cause as an allergic inflammation.
Glaucoma eye drops are used to lower eye pressure. It might get your eyes red until the eye get used to putting the eye drop. Some of them include vasodilators, and they might cause red eye in a couple of hours after putting it on your eye.

・Itchy eyelid and rashes
Allergic reaction to an eye drop may cause itchy eyelid or rash, as like irritating sensation and red eye. The other cause of eyelid rash is a bacterial growth caused by keeping eyelid wet after putting eye drops. Anti-inflammation ointment would work well.

・Increase in eye pressure
A steroid eye drop is used as an anti- inflammation medicine, it’s prescribed for conjunctivitis and uveitis. The concentration of steroid eye drops varies, and the more concentrated, the effect would be stronger. However, steroid eye drops might have side effects and get eye pressure increase. Elevated eye pressure increases your risk for glaucoma. Therefore, steroid eye drops should not be used for long time. Steroid eye drops work well in most cases, but it is important to check your eye pressure regularly while using steroid eye drops.

・Pigmentation around the eye, longer eyelashes
Glaucoma eye drops lower eye pressure. Some of them include components that stimulate eyelash follicles. Therefore, using these eye drops for a long time, eyelashes might get longer and thicker. If eye drops stuck to the eyelid, it would stimulate the synthesis of melanin pigment on skin around eyes. Washing around eyes after using eye drops would prevent these side effects.

・Corneal disorders
Many eyedrops contain preservatives, the most frequently used preservative is benzalkonium chloride (BAK), and it is used in about 80% of eye drops. It would be no problem to use in the short term, but it might have side effects such as corneal damage and disorder in long term use. Therefore, regular check-up is required when using eye drops.

The above is frequent side effects of eye drops. The cause of these symptoms is various, and they should be diagnosed by a doctor whether or not continue current medication. Some side effects will increase a risk for other disorders. If you have any concerns about your medication, please contact the doctor, and follow doctor’s orders about regular check-up.

What is Corneal Neovascularization?
All tissues of the body require oxygen for their proper metabolism. The oxygen enters the body through the lungs, of course, and then passes through the lining of the lungs and enters the circulatory system. From there, it is carried to the rest of the body.

But the cornea is an avascular tissue, meaning it has no blood vessels. Blood vessels growing in the corneal tissue would compromise its transparency, so it must get its oxygen in other ways, through absorption from the tear film and the atmosphere.

When the cornea is deprived of enough oxygen the endothelium pump loses efficiency and is unable to maintain the relatively dehydrated state of the corneal tissue, and therefore it begins to swell. When the decrease in available oxygen becomes chronic, the cornea responds by allowing tiny new blood vessels to grow. This is corneal neovascularization(NV).

Causes of Corneal Neovascularization
There are several known causes of corneal neovascularization. The most common one is contact lens overwear. Overwear can be the result of wearing contacts too many hours in a day, sleeping without removing non-extended wear lenses, using contacts that are no longer transmitting oxygen like they did when new, and allowing the contact lenses to become dirty or to form deposits on their surfaces from inadequate lens care.
Inflammation is another source of corneal neovascularization as the result of trauma or injury, and from blepharitis, uveitis, or keratitis. Corneal ulcers can cause corneal neovascularization, as can glaucoma and other ocular surface diseases like rosacea or lupus.
People who are at risk for corneal neovascularization are
Contact lens wearers, especially those who are non-compliant with lens care
People who have large amounts of nearsightedness (myopia)
Sufferers of dry eye disease
Those who have an ocular surface disease

Management and treatment
The best form of treatment of corneal neovascularization is prevention. If contact lens–related hypoxia is suspected, it is important to cease contact lens use while the NV is addressed. Lenses made of silicon hydrogel material with high oxygen permeability may be prescribed after corneal NV resolution.

Hello. This is the Shinjuku Higashi-guchi Eye Clinic.
This time’s theme is what type of Punctum Plugs do we have?

*What is the Lacrimal point?
Lacrimal point is a hole of your inner eyelid. This is evacuation of your tear. Tear made from your lacrimal gland that is inside of eyelid. When you are blinking, tear cover and moisturize your eye surface. And drainage of tears from your eye, down the duct, and into your nose.

*What is the Punctum Plug?
Punctum Plug made of silicon that use for dry eye patients. If you put in punctum plug on your inner eyelid, your tear’s evacuation will decrease and moisturize on your eye surface.
The cause of dry eye is decreasing your tear and ev***rating your tear easily and so on.
Therefore, if your lacrimal point is closed by punctum plug, you can protect on your eye surface.

*What type of punctum plug do we have?

There are two types of punctum plug, silicon and collagen.
We have the following product in our clinic.

●super flex plugs(made of silicon)
(Manufactured by Eagle Vision, in America)
This punctum plug is a good performance fitting, retainability and comfortability.
It’s easy to fit on anyone’s lacrimal point because they have many diameters.
It’s a high performance for blocking your tear on your eye surface.

●Punctal plug(made of silicon)
(Manufactured by Tomey corporation, in Japan)
It’s easy to put on your lacrimal point even if it’s small because the tip is thin.
You don’t need check up your lacrimal point size. However, they don’t have some size.
It’s also high performance for blocking your tear on your eye surface.
You can use it between 1day to 2 year and half. (7 months on average)

●Keep tear(made of collagen)
(Manufactured by KOKEN, in Japan)
It’s a good performance of collagen punctum plug that is high domestic market share in Japan.
This type of punctum plug is a disposable. Therefore, the effort is weaker than silicon plug.
If you feel uncomfortable your punctum plug made of silicon, it is useful.
You can use it between 1month to 3months.

Not all people with dry eye are suitable for this treatment.
When your lacrimal point closed with punctum plug, waste matter will accumulate on your eye. If you use contact lenses, there is a possibility to put pollution on your wearing contact lenses because of punctum plug.
Please consult with your doctor, if you would like to use punctum plug.

Today’s topic is “Is glaucoma treatable?”

Glaucoma is a disease that leads constructional and functional abnormalities to optic nerves and makes our visual field narrow down. There is no complete treatment for glaucoma, and vision loss due to glaucoma can't be recovered.

There are various causes of glaucoma, the damage of optic nerve is often caused by an abnormally high pressure in your eye. When the intraocular pressure rises abnormally, the optic nerve is compressed and damaged, resulting in a loss of vision in that area.
Glaucoma progresses without subjective symptoms and the visual field defect area expands, finally it leads blindness.

Once the optic nerve is damaged, it is difficult to cure. So, the missing visual field cannot be recovered. However, glaucoma can be slowed or prevented its progress by treating appropriately. The most important thing for treating glaucoma is to reduce intraocular pressure. Controlling intraocular pressure and preventing optic nerve damage can slow the progression of glaucoma. Treatment methods include drug therapy, laser treatment, and surgery. Basically, eye drops that suppress the production of aqueous humor or promote outflow are used, and if the effect is still weak, laser treatment or surgery to create a path for aqueous humor is effective.

Glaucoma is a disease that requires a lifetime hospital visit. Early detection and appropriate treatment are important, so it is recommended to have a regular examination at an ophthalmologist. Please consult your doctor to continue treatment tailored to you.

How is it Important to Use Contact Lenses with UV Protection?

What is Ultraviolet Radiation?
It’s a type of electromagnetic radiation that comes from sun and artificial sources such as tanning beds, mercury v***r lighting, halogen lights, and some type of lasers.
UV rays are divided into three groups:
1. UVA rays – They have the least energy of all the groups. They can cause skin cells’ aging and some indirect damage to cells’ DNA.
2. UVB rays – They have stronger energy than UVA rays. They can cause damage to skin cells’ DNA directly. The main rays cause sunburns.
3. UVC rays – They have the strongest of all groups. Luckily, they don’t reach the ground since they react with ozone high in our atmosphere.

They have different amount of energy and effects, but they are powerful, and they will surely affect human’s body. They come from the sun, but UV rays reflect off the surfaces such as building, water, and pavement, so we have to be careful of the UV exposer even the sunlight is hidden.

How does it affect our eyes?
UV rays are often said that it will damage and age our skin cells, but that can also be said to our eyes. Eyes are always exposed to atmosphere. Since the surface of eyeball, the cornea and conjunctiva which are made of thin mucus membrane, they can easily get damaged from UV rays.
UV rays can cause:
1. Photokeratitis – Also known as ultraviolet keratitis, happens when UV rays burns your cornea and conjunctiva. It causes pain, light sensitivity, and twitching eyelid.
2. Pterygium – UV rays are considered to be one of the reasons for the abnormal growth of the conjunctiva. It will cover the white part of your eyes, and if it keeps on growing, it will start covering your cornea. It causes discomfort, redness, and blurred vision. It is also called surfer’s eye, due to its prevalence among surfers, who spend long time exposed to UV rays.
3. Cataract – UV rays increases the chance to develop cataracts. Cataract will make the lens of your eyes cloudy, and it affects your vision. They are usually formed as you get older. The proteins and fibers aging are the main reason, but UV rays can also affect them.
4. Age-related macular degeneration (AMD): AMD is caused by damaged macula, and it could be accelerated due to the exposure to UV rays. It will make your vision distorted.

How does contact lenses with UV protection help?
Contact lenses contain Ultraviolet absorber, and they absorb UVA and UVB rays and limit the amount that reaches to your conjunctiva and cornea, which is always exposed to UV rays.
Many types of lenses, such as 1day, 2weeks disposable lenses, colored circle lenses, and hard lenses has this UV protection.
These are some of the lenses with UV protection we handle:
1. Hard lenses – Menicon Z, Eyest (Menicon)
, Supreme (Aime), UV-1 (SEED)
2. 1 day lenses – 1day Acuvue Moist, 1 day Acuvue Oasys (Johnson and Johnson), Menicon Premio (Menicon), Precision 1 (Alcon)
3. 2 weeks lenses – Acuvue Oasys (Johnson and Johnson)
4. Colored lenses – 1day Acuvue Define Moist, 2 weeks Acuvue Define(Johnson and Johnson), Eye Coffret 1 day (SEED), Fruttie (Menicon)

These lenses could help your eyes to absorb UV rays. But contact lenses only cover your cornea and only some parts of conjunctiva, so it is also effective to wear sunglasses to protect the entire conjunctiva and surrounding of your eyes.

What is Normal-Tension Glaucoma

Also called low-tension or normal-pressure glaucoma, in normal-tension glaucoma the optic nerve is damaged even though the pressure in the eye is not very high.

Doctors do not know why some people’s optic nerves are damaged even though they have almost normal pressure levels.

Those at higher risk for this form of glaucoma are:
people with a family history of normal-tension glaucoma
people of Japanese ancestry
people with a history of systemic heart disease such as irregular heart rhythm.

What Causes Normal-tension Glaucoma?
The causes of NTG are still unknown. For some reason, the optic nerve is susceptible to damage from even the normal amount of eye pressure. Researchers continue to examine why some optic nerves are damaged by these relatively low eye pressure levels.

How is Normal-tension Glaucoma Different?
Glaucoma is a group of eye diseases that usually share common traits, such as high eye pressure, damage to the optic nerve and gradual sight loss. Most kinds of glaucoma involve elevated eye pressure.

Normal-tension glaucoma (NTG), also known as low tension or normal pressure glaucoma, is a form of glaucoma in which damage occurs to the optic nerve without eye pressure exceeding the normal range. In general, a "normal" pressure range is between 11-21 mm Hg.

How is Normal-tension Glaucoma Treated?
most doctors treat normal tension glaucoma by reducing the eye pressure as low as possible using medications, laser treatments and conventional surgery.
Eyedrops for glaucoma can help decrease eye pressure by improving fluid drain from your eye or by decreasing the amount of fluid your eye makes.
Prescription eyedrop medications include:
Prostaglandin
・Xalatan　・Lumigan

Sympathetic blocking agent
・Timoptol

α2 receptor stimulants
・Alphagan

carbonic anhydrase inhibitor
・Trusopt　・Azopt
