Is glaucoma only caused by diabetes?

No, glaucoma is not only caused by Diabetes. While diabetes can increase the risk of developing certain types of glaucoma, such as neovascular glaucoma, the condition can arise from various other factors, including increased intraocular pressure, age, family history, eye injuries, and certain medications. It is primarily characterized by damage to the optic nerve, often associated with elevated eye pressure, rather than being directly caused by diabetes alone.
