What is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, the bundle of nerve fibers carrying visual information from the eye to the brain, most often due to abnormally high pressure inside the eye. Because it typically progresses slowly and painlessly with peripheral vision loss occurring first, many people are unaware they have it until significant and irreversible damage has already occurred, earning it the nickname the silent thief of sight. There are several types, with open-angle glaucoma being the most common and slow-developing, while angle-closure glaucoma can occur suddenly and constitutes a medical emergency. Early detection through routine eye pressure checks is critical since vision lost to glaucoma cannot be restored.

Causes of Glaucoma

Glaucoma most often results from a buildup of fluid, called aqueous humor, inside the eye due to inadequate drainage, which raises intraocular pressure and gradually damages the optic nerve. Risk factors include older age, family history, naturally high eye pressure, thin corneas, extreme nearsightedness or farsightedness, diabetes, and long-term steroid use. In angle-closure glaucoma specifically, the eye's drainage angle becomes physically blocked, causing a rapid and dangerous pressure spike.

Symptoms of Glaucoma

gradual loss of peripheral or side vision, tunnel vision in advanced stages, eye pain or pressure especially in acute angle-closure attacks, blurred vision, halos appearing around lights, redness of the eye, nausea and vomiting during acute attacks, sudden severe headache

Treatment & Types of Glaucoma in Atari, Lucknow, Uttar Pradesh

Treatment focuses on lowering eye pressure to slow or halt further optic nerve damage, typically starting with prescription eye drops such as prostaglandin analogs, beta-blockers, or carbonic anhydrase inhibitors. Laser procedures such as trabeculoplasty or iridotomy can improve fluid drainage, and surgical options like trabeculectomy or drainage implant devices are used when drops and laser treatment are insufficient. Regular monitoring of eye pressure and visual field testing is essential to track disease progression throughout the patient's life.

Glaucoma includes open-angle glaucoma, the most common form, in which drainage becomes gradually less efficient over years with slow, painless vision loss, and angle-closure glaucoma, which can occur suddenly when the eye's drainage angle becomes physically blocked, causing a rapid, painful pressure spike that constitutes a medical emergency. Less common forms include normal-tension glaucoma, where optic nerve damage occurs despite normal eye pressure, and secondary glaucoma, resulting from another eye condition, injury, or long-term steroid use.
