astigmatism - A refractive abnormality where light is not focused to a point on the retina. This is often caused by the cornea or front window of the eye being elliptical (shaped more like an egg) rather than spherical (shaped like an orange). Refractive correction includes a lens which has focusing power in one axis and no power in the opposite axis. The amount of astigmatism you have will appear in the second number of most glasses prescriptions ie - 4.00 -1.00 x 30°, or -5.00 +1.00 x 120. In both of the above cases you would have 1.00 Diopter of astigmatism.

Sclera - (SKLEH-ruh) The white outer layer of the eye, which is tough and protective. It joins smoothly with the cornea and continues in the back of the eye, connecting with the sheath that covers the optic nerve.

: Epithelium - A layer of cells which protects the tissue below. In the eye, it’s the outside layer of cells on the cornea.

Esotropia - Inward turning of the eyes; crossed eyes. Usually one eye looks straight ahead and the other turns inward. There are several types: Congenital (evident at birth and may continue into Infantile Esotropia); Infantile (usually detected at about 2 months of age and may be accompanied by strabismus and poor gross motor development; Accommodative (usually detected at about two years of age and is related to difficulty with focusing the eyes); and Partially Accommodative (a mix of Basic Esotropia, i.e., non-accommodative, and accommodative esotropia).
