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.
