amblyopia
dimness of vision or the partial loss of sight, especially in one eye, without detectable disease of the eye.
ametropia
any error of refraction in which images do not focus properly on the retina.
anisocoria
a condition in which the pupils are unequal in size.
astigmatism
a condition in which the eye does not focus properly because of uneven curvatures of the cornea.
audiometry
the use of an audiometer to measure hearing acuity.
cataract
the loss of transparency of the lens of the eye that causes a progressive loss of visual clarity.
chalazion
a nodule or cyst, usually on the upper eyelid, caused by obstruction of a sebaceous gland.
cochlear implant
an electronic device that bypasses the damaged portion of the ear and directly stimulates the auditory nerve.
conjunctivitis

diplopia
the perception of two images of a single object.
ectropion
the eversion of the edge of an eyelid.
emmetropia
