Glaucoma is a group of eye diseases which result in damage to the optic nerve and vision loss. A major risk factor is increased pressure in the eye.
The disorders can be roughly divided into two main categories: "open-angle" and "closed-angle" (or "angle closure") glaucoma.
Open-angle chronic glaucoma is painless, tends to develop slowly over time and often has no symptoms until the disease has progressed significantly.
Closed angle glaucoma is usually chronic and asymptomatic but can present all of a sudden as well. This involves sudden eye pain, blurred vision, mid-dilated pupil, redness, nausea and vomiting.
Glaucoma can permanently damage vision in the affected eye, first by decreasing peripheral vision (reducing the visual field), and then potentially leading to blindness if left untreated.
If the condition is detected early enough, it is possible to arrest the development or slow the progression with medical and surgical means. Open angle chronic glaucoma is treated with either glaucoma medication to lower the pressure, or with various pressure-reducing glaucoma surgeries. Treatment of closed angle glaucoma involves medication to bring the intraocular pressure down and laser surgery to the iris to open the drainage angle and hence reduce the eye pressure.
Glaucoma has been called the "silent thief of sight" because the loss of vision often occurs gradually over a long period of time, and symptoms only occur when the disease is quite advanced. Worldwide, glaucoma is the second-leading cause of blindness after cataracts.
We are equipped with Goldmann applanation tonometry, Perkins tonometer, Humphrey Field Analyzer and RNFL OCT for timely diagnosis and management of all types of glaucoma.
