Amblyopia- Decreased visual acuity without any apparent disease of the eye
Aphakia- Absense of the crystalline lens of the eye
Endocyclophototcoagulation (ECP)- Laser treatments; designed to decrease aqueous pressure
Floaters- Small particles consisting of cells or fibrin, which move in the vitreous (usually harmless)
Iritis- Inflammation of the iris, a condition marked by pain, discomfort from light, contraction of pupil, and discoloration on iris
Keratitis- inflammation of the cornea
Nystagmus- An involuntary rapid movement of the eye; may be lateral, vertical, or rotary
Phakic Lens- The natural lens
Ptosis- A paralytic dropping of the upper lid
Tear Film-Layer of watery liquid that bathes the front portion of the eye
Cornea- Chief refracting tissue; the cornea is transparent because of the highly ordered arrangement of collagen fivers within and the absence of blood vessels. There are 5 layers of cornea cells
*Epithelium- outside layer of cells acts a barrier against damage and infection
*Bowmans membrane- tough membrane
*Stroma- consists of collagen fibers and accounts for 90% of the corneas thickness
*Descemets membrane- thin membrane of collagen and fibers
*Endothelium- thin layer of cells that cannot regenerate and are responsible for maintaining partial corneal dehydration and transparency\
Exotropia- A condition in which one or both eyes turn too far outward; sometimes called divergent strabismus
Tropia- A deviation of the eyes from their normal straight alignment
Myopia- Most common refractive error of the eye (Nearsigntness)
Retinopothy- Any disease of the retina- the light sensitive membrane at the back of the eye.
Retina- 2 types of light sensitive cells - Together they allow the eye to comfortably view objects
