Incurable Blindness: The Final Frontier in Vision Restoration
Das AV; Basu SSeminars in Ophthalmology 2023; 38: 394-397
Blindness with no light perception is clinically irreversible. This cross-sectional hospital-based study analyzed patients presenting with no light perception in at least one eye. Between 2010 and 2022, 60,668 (1.85%) such patients were identified, of which 3,476 (5.73%) had bilateral and 57,192 (94.27%) had unilateral blindness. The major causes were glaucoma (21.8%), trauma (17.7%), phthisis bulbi (13.1%), retinal diseases (10.6%), anophthalmos (7.8%), and optic atrophy (4.9%). The majority of the affected individuals were adults (89.9%) and male (64%), and affected individuals were more likely to be from the lower socio-economic strata (3.14%) and from a rural location (1.99%). Despite recent therapeutic advances in ophthalmology, many patients with blindness cannot be restored to sight. Although preventive measures can mitigate sight loss to some extent, regenerative therapies, retinal and ciliary body transplantation, and whole eyeball transplantation need to be developed as sight restorative procedures to help those who currently have no hope of regaining vision.
