Retinoschisis Condition in which the retina splits into layers, sometimes causing blurred vision. It is either inherited or acquired; the acquired form is caused by small cysts in the eye. You may also have floaters.(14 July 2009 - Online article Dr. William Boothe Dallas )
Retinol: Retinol is vitamin A. Carotene compounds (found, for example, in egg yolk, butter and cream) are gradually converted by the body to vitamin A (retinol). A form of vitamin A called retinal is responsible for transmitting light sensation in the retina of the eye. Deficiency of vitamin A leads to night blindness.
Dermatochalasis Excessive, drooping eyelid skin caused by a loss of elasticity in aging skin.
Diopter Unit of measure for the refractive (light-bending) power of a lens; eye care practitioners use it in eyeglass and contact lens prescriptions. A negative number refers to nearsightedness; a positive number, farsightedness. For example, someone with -8.00 diopter lenses is very nearsighted, while someone with +0.75 diopter lenses is only slightly farsighted.
Complication: In medicine, an additional problem that arises following a procedure, treatment or illness and is secondary to it. A complication complicates the situation.Dr. William Boothe
