What is the Pupil?
The pupil is a hole that allows light to pass through the retina. It is found in the middle of the iris of the eye. Most of the light entering the pupil is absorbed by the tissues inside the eye. This makes pupil look black.
What Conditions Affect the Pupil?
In dim light, the pupil gets larger and in bright light, it enlarges. Both pupil respond to light equally and are of the same size. But there’s a condition when pupil sizes are unequal and this causes a person difficulty focusing near objects.
Unequal pupils is a type of eye disorder caused by eye injury or birth defects. In some cases, it is triggered by certain medications that get into the eye.
Abnormalities in the pupil’s size can also be a sign of a wide range of diseases from glaucoma, to lung cancer, stroke, brain tumor, or cluster headaches.
What are the Symptoms of Unequal Pupils?
Symptoms of unequal pupils are double vision, loss of vision, eye pain, drooping eyelids, neck pain, and headache among others.
How are Pupil Disorders Treated?
Consult an eye doctor so you can be given proper advice. Note, however, that it’s not always necessary to treat unequal pupils per se as the disorder causing is the one that needs to be given attention.
