Glaucoma

Glaucoma

Glaucoma is a group of eye diseases in which the retinal nerve fibres are damaged leading to progressive optic nerve damage resulting in decreased vision or even blindness. It is an important reason for poor quality of life due to loss of vision resulting in difficulty in near vision, working in dim light and driving.

Causes of Glaucoma

At the front of the eye, there is a small space called the anterior chamber. Clear fluid flows in and out of the chamber to bathe and nourish nearby tissues. In Glaucoma there is an impairment in the dynamics of this fluid called aqueous humour due to varied causes, some of which are unknown leading to increase in intraocular pressure. Unless this pressure is controlled, it may cause damage to the optic nerve and loss of vision.

Diagnostic Tests for Glaucoma

Glaucoma can be easily diagnosed with simple and effective tests which can help in quantifying the anatomical as well as functional loss due to the disease. These tests are advised regularly during the follow up visits or when the disease is not under control and help in proper management of the patient. Early in the course of the disease these tests may be needed frequently, however frequency of these tests may reduce, as the disease is under control.

Glaucoma Treatment

Glaucoma is one of the leading causes for loss of vision worldwide. However, this vision loss can be avoided by timely intervention, which is usually very simple in the form of medical treatment. Glaucoma cannot be cured, it can usually be controlled. Early diagnosis and treatment helps in improving the quality of life and this vision can be preserved throughout life. Regular monitoring is an essential part of Glaucoma treatment and every glaucoma patient should visit his doctor regularly as advised.
