outer protective layer of the eye; the portion seen on the anterior portion of the eyeball is referred to as the white of the eye
transparent anterior part of the sclera, which is anterior to the aqueous humor and lies over the iris. It allows rays to enter the eye
middle layer of the eye, which is interlaced with many blood vessels that supple nutrients to the eye
the pigmented muscular structure that regulates the amount of light entering the eye by controlling the size of the pupil
watery liquid found in the anterior cavity of the eye. It provides nourishment to nearby structures and maintains shape in the anterior part of the eye
jellylike substance found behind the lens in the posterior cavity of the eye that maintains its shape
oil glands found in the upper and lower edges of the eyelids that help lubricate the eye
reduced vision in one eye caused by disuse or misuse associated with strabimus, unequal refractive errors, or otherwise impaired vision. The brain suppresses images from the impaired eye to avoid double vision
eye disorder characterized by optic nerve damage usually caused by the abnormal increase of intraocular pressure (IOP). If not treated it will lead to blindness
a progressive deterioration of the portion of the retina called the macula lutea, resulting in loss of central vision
yellowish mass on the conjunctiva that may be related to exposure to ultraviolet light, dry climates, and dust. If the yellow mass spreads onto the cornea it becomes a pterygium.
thin tissue growing into the cornea from the conjunctiva, usually caused from sun exposure
hereditary, progressive disease marked by night blindness with atrophy and retinal pigment changes
abnormal condition of squint or crossed eyes caused by the visual axes not meeting at the same point
creation of an artificial opening between the tear (lacrimal) sac and the nose (to restore drainage into the nose when the nasolacrimal duct is obstructed or obliterated)
a laser procedure that reshapes the corneal tissue beneath the surface of the cornea to correct astigmatism, hyperopia, and myopia.
method to remove cataracts in which an ultrasound needle probe breaks up the lens, which is then aspirated
PRK (Photorefractive Keratectomy)
procedure for the treatment of nearsightedness in which an Excimer laser is used to reshape (flatten) the corneal surface by removing a portion of the cornea
an intense beam of light from a laser condenses retinal tissue to seal leaking blood vessels, to destroy abnormal tissue or lesions, or to bond the retina to the back of the eye. Used to treat retinal tears of detachment, diabetic retinopathy, wet macular degeneration, glaucoma, and intraocular tumors
a procedure to repair a detached retina. A strip of sclera is resected, or a fold is made in the sclera. An exoplant is used to hold and buckle the sclera
(digital) process of recording blood vessels (of the eye with fluorescing dye)
