Microscope used examining ; allows cornea, lens and otherwise clear fluids and membranes to be seen in layer-by-layer detail. Usually uncorrectable by eyeglasses or contact lenses. Light is projected into, and movements light reflection from are neutralized (eliminated) with lenses. Can create corneal exposure with excessive drying, tearing, and irritation. Series spoke-like (radial) cuts made in corneal periphery to allow central cornea to flatten, reducing its optical power and thereby correcting nearsightedness. Eyeglasses that incorporate two different powers in each lens, usually near and distance corrections. Inward turning upper or lower eyelid so that lid margin rests against and rubs eyeball. Tiny, white hyaline deposits on bruch's membrane ( retinal pigment epithelium).
Physician (md) specializing in diagnosis and refractive, medical and surgical to and disorders. Determination an eye's refractive error and best corrective lenses to be prescribed. Transparent muccous membrane covering outer surface eyeball except cornea, and lining inner surfaces eyelids. Class ultraviolet lasers that removes tissue accurately without heating it.
Vague discomfort arising from use eyes; may consist eyestrain, headache, and/or browache. Circular channel deep in corneoscleral junction (limbus) that carries aqueous fluid from anterior chamber to bloodstream. Used differentiating normal and abnormal tissue or measuring length eyeball. May gradually advance onto cornea and require surgical removal.
Class ultraviolet lasers that removes tissue accurately without heating it. Space between back iris and front face vitreous; filled with aqueous fluid. Corrected with additional optical power, which may be supplied by a plus lens (spectacle or contact) or by excessive use eye's own focusing ability (accommodation). (Return to top) u uvea, uveal tract (yu-vee-uh).
Light-sensitive retinal receptor cell that provides sharp visual acuity and color discrimination. Almond-shaped structure that produces tears. Central pit in that produces sharpest. Sightless area within visual field a normal.
Examination anterior chamber angle through a goniolens (special type contact lens). Light-sensitive retinal receptor cell that provides sharp visual acuity and color discrimination. Contains a high concentration cones and no retinal blood vessels. Remnants an opaque lens remaining in, or opacities forming, after extracapsular cataract removal.
Light rays entering are bent unequally by different meridians, which prevents formation a sharp image focus on. Inflammation usually subsides, but may need surgical removal. Discipline dealing with diagnosis and defective coordination, binocular, and functional amblyopia by non-medical and non-surgical methods, e.
