Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina. High blood sugar levels can damage the tiny blood vessels, leading to vision problems or even blindness if left untreated. According to the World Health Organization, diabetic retinopathy is a leading cause of blindness among working-age adults.

3. Age-Related Macular Degeneration (AMD)

AMD is a progressive condition that affects the macula, the central part of the retina responsible for sharp, central vision. It is more common in older adults and can lead to significant vision loss. According to the National Eye Institute, AMD is the leading cause of vision loss in people over 50.

4. Retinitis Pigmentosa

Retinitis pigmentosa is a group of inherited disorders that cause a gradual loss of vision due to degeneration of the light-sensitive cells in the retina. It often starts with night blindness and gradually progresses to tunnel vision or complete blindness. The American Academy of Ophthalmology estimates that around 1 in 4,000 people in the United States have retinitis pigmentosa.

5. Optic Nerve Hypoplasia

Optic nerve hypoplasia is a congenital condition where the optic nerve is underdeveloped. This can result in vision impairment or even legal blindness. It is often associated with other developmental abnormalities and may require early intervention for optimal outcomes.

These are just a few examples of ocular fundus anomalies, and there are many other types with their own unique characteristics and implications.
