GRADED A+
✔✔chemosis - ✔✔Excessive edema of the conjunctiva.
✔✔choriorentinitis - ✔✔inflammation of the choroid and retina
✔✔choriod - ✔✔one of the vascular coats of the eyeball, blood vessels
✔✔choroiditis - ✔✔inflammation of the choroid
✔✔ciliary body - ✔✔Structure surrounding the lens that connects the choroid and iris. It
contains ciliary muscles, which control the shape of the lens, and it secretes aqueous
humor.
✔✔coloboma - ✔✔Cleft of the eyeball
✔✔color deficiency - ✔✔inability to perceive color differences as most other people do
✔✔conjunctiva - ✔✔Delicate membrane lining the eyelids and covering the eyeball
✔✔conjunctivitis - ✔✔An inflammation of the conjunctiva that is usually caused by an
infection or allergy; also known as pinkeye.
✔✔convergence - ✔✔A binocular cue for distance based on the degree of tension
required to focus two eyes on the same object
✔✔convex lens - ✔✔a lens that is thicker in the middle than at the edges and bends
light rays towards one another
✔✔cornea - ✔✔clear membrane at the front of the globe covering the iris, pupil, and
anterior chamber. Responsible for 60% of the eyes focusing power. Contains 5 layer
✔✔cyclitis - ✔✔inflammation of the ciliary body
✔✔cycloplegic - ✔✔agent that paralyzes the ciliary muscle and the powers of
accommodation; commonly used in pediatric eye examinations
✔✔cylindrical lens - ✔✔lens used in the correction of astigmatism, has curvature in only
one meridian
✔✔cyst - ✔✔a sac containing fluid
✔✔dacryocystitis - ✔✔inflammation of the lacrimal sac
, ✔✔dark adaptation - ✔✔The process in which the eyes become more sensitive to light
in low illumination.
✔✔degeneration - ✔✔Deterioration or impairment of an organ or part in structure of
cells and the substances of which they are a part is called:
✔✔dellen - ✔✔asx, oval shaped corneal thinning adjacent to raised corneal limbal
lesions. NAFL will pool in the dellen.
✔✔dendritic keratitis - ✔✔viral infection of the cornea usually associated with the
herpes simplex virus and characterized by branching ulceration of the corneal tissue
✔✔depth perception - ✔✔the ability to see objects in three dimensions although the
images that strike the retina are two-dimensional; allows us to judge distance
✔✔detached retina - ✔✔separation of the retina from the choroid in back of the eye
✔✔diopter - ✔✔refractive power of the lens with focal distance of 1 meter, used as unit
of measurement in refraction.
✔✔diplopia - ✔✔Also known as double vision, is the preception of two images of a
single object. Sometimes a symptom of a serious underlying disorder such as multiple
sclerosis or a brain tumor.
✔✔distortion - ✔✔aberration of rays of light
✔✔districhiasis - ✔✔condition in which multiple cilia emerge from one meibomian gland
orifice
✔✔dyslexia - ✔✔A serious difficulty learning to read in the usual way.
✔✔dystrophy - ✔✔Abnormal development
✔✔ectropion - ✔✔outward turning of the rim of the eyelid
✔✔emmetropia - ✔✔-ideal refraction of eye with lens at rest
✔✔entropion - ✔✔inward turning of the rim of the eyelid
✔✔enucleation - ✔✔The removal of an entire mass or part, especially a tumor or the
eyeball, without rupture.
✔✔epiphora - ✔✔Excessive tearing of the eyes
