Glaucoma occurs when alterations in the intraocular fluid production cause pressure in the eye and then it damages the optic nerve. The optic nerve damage can cause severe vision loss which over time results in blindness.
Glaucoma is a leading cause of preventable blindness among eye disorders.
Eye drops can decrease eye pressure by slowing the production of fluids within the eye or increasing the drainage of fluids.
Glaucoma surgery improves the flow of fluids from the eye, relieving pressure on the optic nerve. Surgery can treat glaucoma, but it cannot correct the existing damage on the optic nerve. Therefore, early diagnosis with regular eye examinations is crucial to prevent irreversible damage on optic nerve.
