Common Eye Diseases

These are some of the most common eye diseases:


Conjunctivitis or pink eye is an inflammation of the conjunctiva, the lining of the eyelids. It can be caused by a viral or bacterial infection. It can also be due to an allergic reaction. Symptoms of conjunctivitis include swollen and pink eyes, a burning sensation and sensitivity to light. While it is often a minor infection that can be treated quickly, sometimes it may be an indication of something serious. 


Glaucoma is caused by the fluid inside the eyes slowly building up, increasing pressure which then damages the optic nerve.  The damage may lead to permanent vision loss. The condition is often genetic but can also be caused by an injury. Glaucoma usually has no symptoms except gradually worsening vision. It can be treated by lowering eye pressure but it must be diagnosed early.


Strabismus is a misalignment of the eyes, that makes a person look cross-eyed. It can develop due to neurological or anatomical problems with eye muscles. Strabismus is usually diagnosed at a young age and must be treated quickly to avoid a condition called amblyopia.  Due to misalignment of the eyes, the brain focuses development of vision in one eye, leading to reduced vision in the other. Strabismus can be treated through surgery or vision therapy.


A cataract is the clouding of the clear lens of your eye. It gradually causes problems with your vision, including blurred vision, sensitivity to light, double vision etc. Usually both eyes are affected, however development may be slower in one eye than the other. Cataracts develop slowly due to aging and can be treated through surgery.
