Cataract is the leading cause of curable blindness in India. Now we will see few frequently asked questions about cataract and its treatments.
Glaucoma is a slowly progressive visual loss due to the damage of optic nerve - the part responsible for carrying images to brain. This process is usually due to rise of intraocular pressure that causes irreversible damage to optic nerve fibre bundles leading to a complete blindness if not detected and treated early.
When should one go for a check up for Glaucoma?
Types and symptoms of glaucoma :
Two types are found :-
Chronic open - angle glaucoma : This is the commonest type. The risk increases with age. The drainage angle of the eye becomes less efficient over time, thereby increases pressure within eye, which can damage optic nerve. Typically it has no symptoms in its early stages and vision remains normal. As the disease advances, blank spots begin to appear in your field of vision, gradually becomes larger, optic nerve fibres die and eventually blindness results.
Closed - angle glaucoma : Here the angle of the eye is too narrow to drain the fluid inside the eye properly. Symptoms may include blurred visionpe is treated quickly blindness can result. But this type of glaucoma develop slowly without any symptom prior to and acute attack.
