Blinding Diseases


Blindness can occur as a result of a number of infectious, non-communicable diseases, and injuries. The main infectious causes include trachoma and onchocerciasis and the main NCD causes are cataract and glaucoma. Trachoma alone accounts for 15% of the world’s blindness. Depending on the cause, up to 80% of blindness and serious visual loss could be prevented or treated. Face washing, general hygiene, preventive chemotherapy, early diagnosis, and treatment are commonly used interventions.
