Corneal disease is a major cause of visual impairment and blindness worldwide, particularly in low- and middle-income countries. Unlike other causes of blindness such as cataract or glaucoma, corneal blindness is often preventable and affects individuals across all age groups, including young adults and children. Causes vary geographically but commonly include infections and trauma, including chemical injury. Managing corneal disease requires early recognition, prompt treatment, and, in some cases, access to advanced surgical care—resources that may not always be available in under-resourced settings. Community-based approaches focusing on prevention, early detection, and appropriate referral are essential to reduce the burden of corneal blindness.
