ophthalmology
speciality related to the study of the eye
ophthalmologist
physician who specializes in the study and treatment of the eye
Optometrist
one who specializes in measuring the eye
ocular
pertaining to the eye
blepharospasm
involuntary muscular contraction of the eyelid
blepharitis
inflammation of the eyelid
keratoplasty
surgical repair or reconstruction of the cornea
dacryocyst
lacrimal sac where tears are collected before they flow to the nose
dacryocystitis
inflammation of the lacrimal sac
phacolysis
break down of the lens
phakoma
tumor-like condition of the lens
photophobia
abnormal fear of sensitivity to light
presbyopia
vision condition common with old age
cyclotomy
incision in the ciliary body
iritis
inflammation of the iris
iridectomy
excision of a portion of the iris
anterior chamber
fluid-filled space between the cornea and iris
aqueous humor
watery liquid secreted by the ciliary processes that fills the anterior and posterior chambers of the eye and provides nourishment for the cornea, iris, and lens (humor = fluid)
canal of Schlemn
duct in the anterior chamber that carries filtered aqueous humor to the veins and bloodstream
choroid
vascular layer beneath the sclera that provides nourishment to the outer portion of the retina
ciliary body
ring of tissue behind the peripheral iris that is composed of ciliary muscle and ciliary processes
ciliary muscle
smooth muscle portion of the ciliary body, which contracts to assist in near vision
ciliary processes
epithelial tissue folds on the inner surface of the ciliary body that secrete aqueous humor
conjunctiva
mucous membrane that lines the eyelids and outer surface of the eyeball
cornea
transparent, anterior part of the eyeball covering the iris, pupil, and anterior chamber that functions to refract (bend) light to focus a visual image
eyelid
movable, protective fold that opens and closes, covering the eye
palpebra
movable, protective fold that opens and closes, covering the eye (same as eyelid)
fovea centralis
pinpoint depression in the center of the macula lutea that is the site of sharpest vision (fovea = pit)
fundus
interior surface of the eyeball, including the retina, optic disk, macula, and posterior pole (curvature at the back of the eye) (fundus = base)
glands of Zeis
oil glands surrounding the eyelashes
meibomian glands
oil glands located along the rim of the eyelids
iris
colored circle; colored part of the eye located behind the cornea that contracts and dilates to regulate light passing through the pupil
lacrimal gland
gland located in the upper outer region above the eyeball that secretes tears
lacrimal ducts
tubes that carry tears to the lacrimal sac
