Glaucoma is a group of eye diseases that damage the optic nerve, often due to increased pressure inside the eye. This damage can lead to gradual vision loss and, if untreated, blindness. It is one of the leading causes of vision impairment worldwide, especially among older adults.
The primary cause of glaucoma is elevated intraocular pressure (IOP), which occurs when fluid builds up in the eye instead of draining properly. However, some types of glaucoma can develop even with normal eye pressure. Risk factors include:
The most common types include:
In the early stages, glaucoma often has no noticeable symptoms. As it progresses, peripheral (side) vision may begin to fade. Regular eye exams, including pressure checks and optic nerve evaluations, are essential for early detection.
While glaucoma cannot be cured, treatments can slow its progression. Options include prescription eye drops, laser therapy, and, in advanced cases, surgery.
Because vision loss from glaucoma is irreversible, early diagnosis and treatment are critical. If you have risk factors or are experiencing vision changes, schedule an eye exam to protect your eyesight.
