Glaucoma is a disease of the eye which exhibits a typical optic neuropathy which results in progressive visual field loss.The most important risk factor is raised intraocular pressure.Risk factors for glaucoma include age above 40 years, diabetes, myopia, mature cataract, trauma, certain retinal diseases and a family history of glaucoma. At Nandadeep Hospital the patient is investigated thoroughly with use a of Perimetry, Ocular coherence tomography (OCT) and then the treatment is personalised to the patient to maintain his vision and quality of life.Types of GlaucomaChronic Open Angle Glaucoma
The most common type of glaucoma, known as chronic open angle (COAG) or primary open angle, occurs when the canals draining the eye of aqueous humor become clogged. This blockage can gradually increase pressure within the eye to damaging levels. No pain occurs, so individuals are usually unaware that these changes are occurring. There are no early signs or symptoms but over the years vision will be lost starting in the periphery and moving towards the central vision.Acute Angle Closure Glaucoma
When eye pressure builds up rapidly, it is called acute angle-closure glaucoma. This type of glaucoma commonly occurs in individuals who have narrow anterior chamber angles. In these cases, aqueous fluid behind the iris cannot pass through the pupil thus pushing the iris forward, preventing aqueous drainage through the angle. It is as though a sheet of paper floating near a drain suddenly drops over the opening and blocks the flow out of the sink.
In cases of acute angle closure glaucoma, one may experience blurred vision, halos around lights, deep pain behind the eye, nausea, and vomiting. Nandadeep advises its patients to have periodic eye examinations for early detection of glaucoma.
