CBSE Class 10 Answered

Glaucoma: It is prevalent, sight-threatening disease in which the pressure of the fluid in the eye becomes so increased that unless promptly and properly treated, the internal eye structures are permanently damaged.

Vision loss is caused by damage to the optic nerve. This nerve acts like an electric cable with over a million wires. It is responsible for carrying images from the eye to the brain.

There is no cure for glaucoma—yet. However, medication or surgery can slow or prevent further vision loss. The appropriate treatment depends upon the type of glaucoma among other factors. Early detection is vital to stopping the progress of the disease.

Hope this helps.
