Have you ever wondered what the head-mounted device is that retina specialists use to get a close look at the retina?

Indirect ophthalmoscopy is performed in combination with other diagnostic tests to help diagnose and monitor eye conditions such as age-related macular degeneration, diabetic retinopathy, and retinal detachments.

During the exam, the retina specialist shines a bright light into the eye from a special head-mounted device. The retina specialist then uses another lens, called a handheld lens, to magnify the image of the back of the eye and examine it in detail.

Do you recognize this black-and-white grid with a dot in the middle? It's called an Amsler grid, named after Swiss ophthalmologist Marc Amsler, who developed it in 1947.

Your retina specialist may ask you to look at an Amsler grid regularly to monitor for changes in your vision, which could be age-related macular degeneration ( ).

To check your vision, cover one eye at a time (keeping your glasses on if you wear them), hold the grid 12 inches away, and look at the dot. If the lines appear wavy, dim, irregular, or fuzzy, let your eye doctor know immediately.
