Glaucoma is a group of eye disorders that cause damage to the optic nerve and loss of vision. Some of its symptoms are eye pain, blurred vision, redness of the eye, nausea, etc. Open-angle glaucoma, closed-angle glaucoma and normal-tension glaucoma are a few of its types. Open-angle glaucoma is the most common type. It develops slowly and the drainage angle for fluid within the eye remains open. It results in vision loss and sometimes permanent blindness. Closed-angle glaucoma involves severe eye pain, mid-dilated pupil, blurred vision and nausea. There are certain risk factors for glaucoma. These include increased pressure in eyes, high blood pressure and a family history of the condition. Techniques such as tonometry, ophthalmoscopy, gonioscopy, pachymetry, etc. are used in the diagnosis of glaucoma. Strategies such as surgery, laser treatment and glaucoma medications are available for the management of glaucoma. Laser treatments are usually effective in both open-angle and closed-angle glaucoma.
