What causes glaucoma?

Glaucoma is primarily caused by an increase in intraocular pressure. This elevated pressure can damage the optic nerve, which is crucial for vision, potentially leading to vision loss or blindness if left untreated. The condition typically results from inadequate drainage of the aqueous humor, which is the fluid within the eye. Increased pressure can be asymptomatic in the early stages, making regular eye examinations essential for early detection and management.

While cyst formation in the eyelid, infection of the eyelash follicle, and progressive deterioration of the retina can affect eye health, they do not inherently cause glaucoma. These conditions may relate to other eye issues but are distinct from the primary pathology associated with glaucoma, which revolves around intraocular pressure dynamics and optic nerve damage. Understanding the primary cause helps in both prevention and treatment strategies for glaucoma.
