What is fundus disease?

Retinal diseases refer to a group of conditions that affect the tissues at the back of the eye, including the retina, optic nerve, and vitreous body. Common diseases include vitreous degeneration, age-related macular degeneration, and retinal artery occlusion.

1. Vitreous Degeneration

This condition is commonly associated with aging. It causes the vitreous to change from a gel-like state to a more liquefied form, often accompanied by shrinkage and liquefaction. Typical symptoms include cloudiness in the eye, blurred vision, and the appearance of small dark spots or wavy lines in the visual field.

2. Age-Related Macular Degeneration

This disease causes localized or widespread damage to the retina. Affected by factors such as thinning of the macula and retinal detachment, patients may experience symptoms including blurred or reduced central vision, visual distortion, and changes in color perception.

3. Retinal Artery Occlusion

Retinal artery occlusion occurs when the retinal artery becomes blocked. In the early stages, there may be no obvious signs or symptoms. As time progresses, patients may gradually develop clinical manifestations such as a cherry-red spot in the eye, decreased vision, or sudden blindness.

In addition, retinal diseases may also include other conditions such as retinal detachment and optic nerve tumors.
