achromatopsia
profound inability to see color; color blindness
amblyopia
loss of vision not due to any disease; lazy eye
astigmatism
uneven bending of light rays caused by irregular curvature of cornea
cataract
lens becomes cloudy or opaque, resulting in whole vision field becoming blurry
corneal abrasion
scraping away of outer layer of cornea
cryoextraction
procedure to remove lens w/ cataract using extreme cold probe
diabetic retinopathy
development of small hemorrhages & edema in retina as result of diabetes mellitus
glaucoma
condition resulting from increase in intraocular pressure
hyperopia
visual condition in which person can see in distance but trouble reading material at closer range; farsightedness
laser-assisted insitu keratomileusis
correction of myopia using laser surgery to remove minute slices of corneal tissue
laser retinal photocoagulation
using laser to make pinpoint scars to stabilize detached or torn retina
mascular degeneration
deterioration of macula lutea of retina
myopia
visual condition in which person can see things up close but not far; nearsightedness
nyctalopia
poor vision at night or in dim light; night blindness
nystagmus
jerky-appearing involuntary eye movement
photophobia
excessive sensitivity to light, leading to avoidance
photo-refractive keratectomy
use of laser to reshape cornea to improve visual acuity
radial keratotomy
surgery w/ spoke-like incisions in cornea to flatten it to correct myopia
refractive error
defect in ability of eye to bend light rays to focus image properly on fovea centralis
retinal detachment
occurs when retina becomes separated from choroid layer, damaging blood vessels & nerves, resulting in blindess
strabismus
weakness of external eye muscle, resulting in eyes looking in different directions at same time; cross eyed
stye
small purulent infection of sebaceous gland of eye; hordeolum
