Special Senses (eyes and ears) Pathology Terms EYE
brain disregards images from the weaker eye and relies on stronger eye.
abnormal curvature of the cornea that distorts visual images
noncontagious inflammation of eyelash follicles and oil glands along eyelids
cloudiness of the lens,
From:protein deposits as a result of aging, disease or trauma.
Side effect from smoking or medications
blind spot in the center of visual field
small benign cyst in the eyelid
Formed by: distention of meibomian gland (sebaceous gland)
inflammation of the conjunctiva
progressive damage to vessels and other structures of retina, can cause blindness
lower eyelid turned outward and droops more with aging
eyelids edges turned inward and rub the surface of eye.
usually affecting lower eyelid
sudden blockage of aqueous-humor outflow causes a rapid increases in intraocular pressure.
Can cause loss of vision
aqueous humor drains too slowly causes intraocular pressure.
can cause vision loss
infected sebaceous gland of eyelid
rays focus behind retina
hypertension causes destructive retinal changes
inflammation of the cornea
vision of 20/200 or less or visual field of 20 degrees or less in the better eye
*loss in visual acuity that prevents a person from performing work requiring eyesight*
macular deterioration resulting in central vision loss
Categorized as atrophic (dry) or exudative (wet)
nearsightedness (only see a short distance)
light rays focus in front of the retina
involuntary back and forth or cyclical movements of the eyes
study of the structure, functions and diseases of the eye
unable to focus on near objects,
occurs in people entering their 40s
separation of inner sensory layer of retina from outer pigment layer
misalignment of eyes
effects depth perception
Exotropia = eyes turned outward
Esotropia = eyes turned inward
Hypertropia = eyes upward
hypotropia = eyes downward
intraocular inflammatory disorder
