Glaucoma is a serious group of eye conditions that harm the optic nerve. The damage often occurs due to high pressure in the eye, known as intraocular pressure (IOP). If not treated, glaucoma can lead to vision loss and even blindness. It is among the top causes of irreversible blindness globally. The disease generally develops slowly, showing no noticeable symptoms until significant damage has already occurred. This makes regular eye check-ups essential for early detection.
Causes of Glaucoma
The leading cause of glaucoma is increased intraocular pressure. This pressure rises when the fluid in the eye, called aqueous humor, fails to drain properly. As a result, damage occurs to the optic nerve. Other factors that increase the risk of developing glaucoma include:
Age: Individuals over 60 are at greater risk.
Ethnicity: African Americans are more likely to develop glaucoma earlier in life.
Family History: The condition often runs in families.
Medical Conditions: Diseases such as diabetes and hypertension, along with eye injuries, can elevate the risk.
