SPECIAL ANNOUNCEMENT:

Join us for the Lange Eye Institute Mardi Gras Festival

February 21st | 10 AM – 2 PM

We invite the entire community to come out, celebrate, and learn more about eye health, nutrition, and wellness.

CATARACTS & NUTRITION
Dr. Lange and Dr. Summerton discuss why diabetics are more prone to cataracts, explaining the role of elevated blood sugar, oxidative stress, and glycation in damaging the lens of the eye. They also review nutritional strategies that may help support lens clarity and overall eye health.

OPTILIGHT IPL & OPTILIFT RESULTS

The doctors share what they are seeing after over a year of treating patients with OptiLight and OptiLift technologies, including improvements in dry eye symptoms, eyelid function, and blink dynamics. These innovative therapies are showing promising results for patients suffering from dry eye disease.

GLAUCOMA – THE SILENT THIEF OF SIGHT
During a live caller discussion, the doctors emphasize that glaucoma often has no early warning signs. They stress the importance of routine comprehensive eye exams to detect glaucoma early and prevent vision loss.

They explain how glaucoma is diagnosed, including:

• Eye pressure testing

• Optic nerve evaluation

• Visual field testing

• OCT imaging

GLAUCOMA & WHOLE-BODY HEALTH
The discussion expands into how systemic health impacts glaucoma, including:

• Ocular perfusion pressure (blood flow to the optic nerve)

• The dangers of blood pressure that is too low

• How sleeping more than 9 hours may negatively affect glaucoma

• The impact of sleep apnea on optic nerve health

NATURAL SUPPORT FOR EYE HEALTH

Dr. Lange and Dr. Summerton discuss nutritional and lifestyle strategies that may support healthy vision and circulation, including:

• Omega-3 fatty acids

• Antioxidants

Dr. Michael Lange and Dr. Susan Summerton hosted Ask the Dr this morning from Salem Media, opening the show with a discussion on the power of proper nutrition and the importance of consuming adequate protein in the morning to support metabolism, muscle health, energy, and brain function.

During a caller discussion, Dr. Lange emphasized the importance of xanthophyll carotenoids, particularly lutein and zeaxanthin, which play a critical role in protecting the macula and supporting long-term visual performance. The doctors also discussed cholesterol and statin medications, and how these drugs may interfere with the absorption of fat-soluble nutrients, including lutein and zeaxanthin. Dr. Lange recommends Fortifeye Focus for anyone who spends extended time on computers or digital devices, as these carotenoids help protect the macula from blue-light damage.

Both doctors highlighted what Dr. Lange described as a missing nutrient in today’s Standard American Diet—black currant seed oil. Unlike most oils, black currant seed oil naturally contains omega-6 (GLA), omega-3 (ALA), and omega-9 fatty acids, making it a uniquely balanced essential fat source. Dr. Lange explained that GLA (gamma-linolenic acid) is particularly lacking in modern diets and plays a key role in controlling inflammation, supporting dry eye, skin health, joint comfort, and overall cellular function. Fortifeye Black Currant Seed Oil / GLA was discussed as an effective way to restore this critical fatty acid balance.

The show also addressed nutrition strategies for constipation, discussed eye floaters and warning signs to be aware of, and offered practical guidance for improving overall systemic and ocular health.

Dr. Lange took time to express gratitude to several mentors from Louisiana who helped shape his career, including Dr. Richard K. Lange (his father), Dr. Charlie Glazer of St. Charles Vision, and Dr. Steve Brint of Eye Surgery Center of Louisiana.

The program concluded with an in-depth segment on dry eye disease, focusing on two advanced technologies designed for more resistant cases—Lumenis OptiLight and OptiLift, available exclusively at the Lange Eye Institute. Dr. Summerton also discussed the benefits of appropriate light exposure for memory, energy, and concentration, while emphasizing the importance of limiting digital screen time at night to support restorative sleep.

In the second part of today’s Ask the Doctor, Dr. Michael Lange and Dr. Susan Summerton discussed exciting advancements in photobiomodulation therapy and its expanding role in both eye and systemic health.

We explained what photobiomodulation therapy (PBM) is and how it works. PBM uses specific wavelengths of low-level red and near-infrared light to stimulate mitochondrial function, increase cellular energy (ATP), improve circulation, and reduce inflammation. As more companies bring this technology to market, increased competition is expected to drive costs down, making this promising therapy more accessible to patients.

Dr. Lange and Dr. Summerton shared their enthusiasm for photobiomodulation therapy as a supportive treatment option for macular degeneration, diabetic retinopathy, and dry eye disease. Dr. Kane has noted that when diet and supplementation are optimized, this technology may work even more effectively, reinforcing the importance of combining advanced technology with proper nutrition.

Dr. Summerton also weighed in on chelation therapy, explaining how reducing toxic metal burden and oxidative stress may further support cellular health, circulation, and inflammation control. When used appropriately and combined with nutrition and lifestyle optimization, chelation therapy may enhance overall systemic and ocular health.

An important discussion followed on the often-overlooked connection between dry eye disease and atrial fibrillation (AFib). Dr. Lange explained that many patients with both conditions commonly share deficiencies in:
• Magnesium
• Potassium
• Sodium chloride
• Omega-3 fatty acids
• Hydration

These deficiencies may contribute to inflammation, nerve dysfunction, poor tear quality, impaired circulation, and cardiac rhythm instability.

🌿 NATURAL SUPPORT FOR DRY EYE & ATRIAL FIBRILLATION

Dr. Lange and Dr. Summerton reviewed natural strategies that may help support both dry eye and AFib, including:
• Proper hydration with high-quality water
• Restoring electrolyte balance (magnesium, potassium, sodium chloride)
• Consistent intake of omega-3 fatty acids
• Anti-inflammatory nutrition
• Targeted supplementation when appropriate

We also discussed Fortifeye Complete, which serves as a high-quality multivitamin and eye vitamin all in one, helping simplify supplementation while supporting both ocular and systemic health.

This episode highlights the importance of integrating nutrition, lifestyle changes, supplementation, chelation strategies, and emerging technologies to support long-term eye health, heart health, and overall wellness.

Thank you for listening to Ask the Doctor, where science, nutrition, and real-world clinical experience come together.

🎙️ ASK THE DR – TODAY’S SHOW RECAP

Today’s episode of Ask the Dr was hosted by Dr. Michael Lange and Dr. Susan Summerton, delivering an information-packed program focused on eye health, wellness, longevity, and disease prevention.

L🎭 Mardi Gras Extravaganza Announcement

The doctors announced the upcoming Mardi Gras Extravaganza at the Lange Eye Institute, taking place February 21st in The Villages. Everyone is invited to attend this fun, educational, community event.

💪 Fortifeye Super Vegan Protein BOGO

Dr. Lange discussed the Buy One, Get One FREE promotion currently running on Fortifeye Super Vegan Protein, available for a limited time on the Fortifeye website.

👁️ Dry Eye Treatment – Natural & Advanced Options

Both doctors reviewed comprehensive dry eye care, including:

• Lid hygiene and lid scrubs

• Warm/hot compress therapy

• Omega-3 fish oil, emphasizing rTG (re-esterified triglyceride) omega-3, such as Fortifeye Super Omega

They also discussed advanced in-office treatments:

• Lumenis OptiLight (IPL therapy)

• Lumenis OptiLift to help lower-lid laxity and meibomian gland dysfunction

🏋️ Creatine & Weight Management

The doctors reviewed new and existing research showing that creatine:

• Supports muscle strength, energy, and overall health

• May help build muscle while supporting fat loss

• Can be used as part of a weight-management strategy, not just for athletes
Both doctors discuss the soon to be available Fortifeye Fit Meal one of the most advanced meal replacemnts on the market.

🟢 Glaucoma Awareness Month – Natural Support

In recognition of Glaucoma Awareness Month, the doctors discussed:

• Natural strategies that may support optic nerve health

• The role of omega-3 fatty acids, Mirtogenol, and Neumentix in supporting ocular blood flow

L⚠️ These natural approaches do NOT replace medical or surgical glaucoma treatment and are intended only to complement prescribed care. Period.

👁️ Ocular Perfusion Pressure & Blood Pressure

The doctors explained how ocular perfusion pressure (OPP) plays a critical role in glaucoma risk and how both high and low blood pressure can negatively affect optic nerve blood flow.

They emphasized that low diastolic blood pressure, especially at night, can significantly reduce ocular perfusion pressure. Multiple studies show that individuals with low OPP may have a 2–6× higher risk of developing glaucoma.

A diastolic ocular perfusion pressure (DOPP) below ~50 mmHg is associated with:

• Higher glaucoma prevalence

• Faster disease progression

• Increased optic nerve damage

The key takeaway: glaucoma is not only an eye-pressure disease—it is also a vascular disease. Proper blood-pressure management is a critical part of glaucoma care.

Patients with glaucoma should always work closely with their eye doctor and primary care physician. This information is educational and supportive—not a replacement for treatmen

A new genetic study just came out suggesting that high consumption of instant coffee—not brewed coffee—may be linked to a significantly increased risk of dry macular degeneration, in some cases close to a seven-fold increase. Now, this is not a definitive clinical trial, and it does not prove causation, but it raises an eyebrow. Instant coffee is highly processed, and the drying methods may create compounds that promote oxidative stress in susceptible individuals. Traditional brewed coffee did not show this same association.
If you’re at risk for macular degeneration, it may be smart to choose fresh brewed coffee over instant while we wait for more research.

New research from China suggests instant coffee consumption may significantly increase the risk of developing dry age-related macular degeneration (AMD), with researchers recommending people at high risk for AMD should avoid instant coffee altogether.

Dr Lange and Dr Summerton uncover the hidden causes of Dry Eye and Meibomian Gland Dysfunction — from Demodex mites to clogged glands — and share the latest natural, nutritional, medical, and advanced laser treatments including Xdemvy, OptiLight IPL, OptiLift, and Fortifeye Advanced Dry Eye Therapy.

In this episode of Ask the Dr, Dr Michael Lange and Dr Summerton discuss the root causes and the most effective treatments for Meibomian Gland Dysfunction, one of the leading causes of dry eye disease. They explain how clogged meibomian glands reduce the oily layer of the tear film, leading to dryness, irritation, and fluctuating vision.

A key focus is the Demodex mite, a microscopic parasite that lives in the eyelash follicles and meibomian glands. These mites crawl into the glands, lay eggs, and regurgitate inside, triggering inflammation and gland obstruction that worsen MGD symptoms.

The doctors highlight three major treatment approaches — natural, medical, and advanced technological solutions

Maintaining healthy antioxidant mineral status (especially manganese) and minimizing arsenic exposure (from water or contaminated food) could help protect ocular surface tissues and reduce pterygium risk.

Excess arsenic and low manganese levels were associated with greater risk of pterygium among Korean adults.
This supports the hypothesis that trace-element imbalance and oxidative stress contribute to pterygium development.

Pterygium often starts on the inner (nasal) side of the eye and extends outward. The surface may appear pink/red due to blood vessels, and can distort vision if it grows over the central cornea.
The wing-shaped fibrovascular tissue growth on the eye’s conjunctiva that can invade the cornea and impair vision.

It’s linked to UV exposure and oxidative stress, but the exact cause is still unclear.
• Arsenic (As) can increase oxidative stress and damage eye tissues.
• Manganese (Mn) and zinc (Zn) are trace elements that support antioxidant enzymes (e.g., superoxide dismutase, metallothionein), potentially protecting against oxidative damage.

What Is Astaxanthin & Why It Matters
• Astaxanthin is a red/orange pigment (a xanthophyll carotenoid) found in algae, seafood (salmon, shrimp), and some microorganisms. 
• It accumulates in stressed algae (Haematococcus pluvialis) when they shift from green → red under light/nutrient stress. 
• It’s highly lipophilic and spans the cell membrane, making it effective at neutralizing free radicals in both the membrane’s lipid core and aqueous environments. 

Key Benefits & Effects
1. Antioxidant & Membrane Protection
• Protects lipid membranes from oxidative damage (especially better than vitamin E in some contexts). 
• Helps maintain mitochondrial and cellular integrity under stress.

2. Skin & Anti-Photoaging
• Reduces UV-induced damage, slows collagen breakdown, helps with skin elasticity, moisture, and wrinkle depth in early clinical trials. 
• May counter UV-caused immunosuppression in skin. 

3. Metabolic / Cardiometabolic Effects
• In adults with type 2 diabetes, 8 mg/day for 8 weeks improved visceral fat, triglycerides, blood pressure, and insulin sensitivity. 
• Protects pancreatic β-cells from glucose toxicity in animal/mouse models. 
• Promotes better glucose uptake in muscle via enhancing GLUT4 translocation.

4. Eye / Vision / Digital Strain
• In a RCT of children, 6 mg/day of astaxanthin reduced digital eye strain (both acute and chronic) by ~27%. 
• Other studies (4–12 mg/day) show improved ocular blood flow, retinal circulation, and better performance of ciliary (focusing) muscles. 

5. Exercise / Muscle / Performance
• In older adults: 8 weeks of astaxanthin improved walking distance, climbing capacity, and recovery metrics. 
• In overweight adults: 12 mg/day for 4 weeks improved endurance, strength, and muscle quality. 
• In cyclists: small doses (4 mg) improved power output and cut time in 20 km trial. 

6. Whole-Algae / Whole-Food Context
• Astaxanthin in its natural algal matrix includes co-nutrients (PUFAs, proteins, antioxidants) that may enhance or stabilize its effects. 
• The “red food” concept: red and orange phytonutrients often come with supporting compounds; many Americans don’t consume enough of these. 

From Whole Algae to Clinical Insight What is Astaxanthin It is the pink hue of shrimp, the rosy blush of flamingos, the vivid red of lobster, and even the
