There is a wide range of diseases and conditions that can affect our eyes, causing visual impairment and often blindness. The leading causes of blindness are:
- Cone-rod dystrophy - Cone-Rod Dystrophy (CRD) is an inherited progressive disease that causes deterioration of the cone and rod photoreceptor cells and often results in blindness.
- Diabetic retinopathy - Diabetic retinopathy is a common diabetic eye disease caused by changes in retinal blood vessels.
- Glaucoma - Glaucoma is a group of eye conditions in which the optic nerve is damaged due to changes in eye pressure. Glaucoma is the leading cause of irreversible blindness.
- Stargardt's disease - Stargardt disease, or fundus flavimaculatus is form of macular dystrophy that begins early in life. It is an inherited juvenile macular degeneration that causes progressive vision loss usually to the point of legal blindness.
