Common examples are diabetes, hypertension, infections and allergies. Besides, there are few disorders that affect the retina specifically like detachment, macular degeneration in the elderly (Age Related Macular Degeneration) and disorders in premature babies (Retinopathy of Prematurity).
These retinal conditions can present with or without reduction in vision. Your retina specialist will be able to help you after checking your eyes in the clinic and, if needed, using additional retinal scans to pinpoint the problem.
For any such medication, consult Dr. Sonia Maheshwari Kothari one of the Best Retina specialist in Ghatkopar.
