define ANISOCORIA
pupils unequal in size from congenital, head injury, aneurysm, or pathology of CNS
describe CATARACT
loss of transparency of lens from accumulation of protein in lens, age, congenital, injury, or disease leading to progressive loss of visual clarity
define DIABETIC RETINOPATHY
damage to retina as complication of uncontrolled diabetes
define ENDOPHTHALMITIS
inflammation of intraocular fluids
describe FLOATERS
particles of cellular debris floating in vitreous humor causing shadows on retina appearing as squiggly lines, small specks, or hair-like strands; common; caused by retinal detachment, shrinkage & detachment of collagen fibers in vitreous humor, or happens normally
aka: floaters
vitreous floaters
define PHOTOPSIA
flashes of light from damage to eye or migraines
define MIOSIS
contraction of pupil from light or drugs
define MYDRIASIS
dilation of pupil from disease, trauma, or drugs
describe NYSTAGMUS
involuntary, constant, rhythmic movement of eye leading to limited visual acuity from congenital disorder, neurological injury, or drug use
describe PAPILLEDEMA
swelling & inflammation of optic nerve @ pnt of entrance through optic disk that increases intracranial pressure leading to swelling
aka: papilledema
choked disk
describe RETINAL DETACHMENT
emergency condition of separation of some/all of retina from choroid which can lead to complete detachment & blindness if untreated; s/s: floaters, flashing lights, shadows gradually obscure vision
describe RETINITIS PIGMENTOSA
progressive degeneration of retina affecting night & peripheral vision & causes dark pigmented spots on retina
describe RETINOBLASTOMA
rare eye cancer from growth of retinal cells; most common intraocular cancer in kids
describe GLAUCOMA
group of diseases w/high IOP causing damage to retinal nerve fibers & optic nerve leading to eventual blindness; caused by blockage of fluid flow in & out eye
describe OPEN ANGLE GLAUCOMA
most common; trabecular meshwork gradually blocked leading to pressure & not noticed until damage to optic nerve; detected thru eye exams
aka: open angle glaucoma
chronic glaucoma
describe CLOSED ANGLE GLAUCOMA
opening between cornea & iris narrows so fluid can't reach trabecular meshwork causing a sudden increase in IOP; s/s: severe pain, nausea, eye redness, blurred vision, & blindness
aka: closed angle glaucoma
acute glaucoma
describe MACULAR DEGENERATION
gradually progressive & incurable condition where macula @ center of retina is damaged leading to loss of central vision
describe AGE RELATED MACULAR DEGENERATION (AMD)
leading cause of vision loss in ppl +60 yrs; starts in 1 eye & develops in other
define DRY MACULAR DEGENERATION
90% of all AMD w/slow deterioration of macula cells
describe WET MACULAR DEGENERATION
advanced form of dry AMD where new vessels grow & leak causing damage to macular cells leading to rapid & severe vision loss
