Question | Answer |
---|---|
an opacity of the lens due to proteins reducing visual acuity | cataracts |
incidence of cataracts | 92% of people over the age of 75, F>M |
risk factors for cataracts | aging, smoking, chronic steroid use, exposure to UV light, atopic dermatitis, diabetes |
symptoms of cataracts | progressive decrease in visual acuity with out pain, second sight-temporary improvement in presbyopia, glare increased with bright lights |
PE findings with cataracts | opacity is teh black or grayish silhouette against red reflex. complete cataract is seen as a whitish blue clouding through pupil |
incidence of glaucoma | affects 2.5 million americans-80,000 legally blind |
risk factors for glaucoma | over the age of 40, AA, Mexican americans over the age of 60 |
most common form of glaucoma | open angle |
leading cause of blindness | open angle glaucoma |
prevention of glaucoma | annual screening of IOP and visual fields |
treatment for open angle glaucoma | beta blockers, miotics(pilocarpine), prostaglandin agonist (xalatan), carbonic anhydrase inhibitor (trusopt, diamox) |
which glaucoma is an ocular emergency | acute angle closure glaucoma |
S&S of acute angle closure glaucoma | IOP>21mm Hg, conjunctiva injected, mid-dilated non-reactive pupil, shallow chamber, blurred vision, halos, ocular pain, N/V |
treatment for acute angle-closure glaucoma | lie supine, medical emergency (911), laser peripheral iridotomy after IOP controlled |
__ causes progressive loss of central vision | macular degeneration |
leading cause of vision loss in adults >65 | macular degeneration |
three types of macular degeneration | dry (atrophic 90%), drusen, wet (exudative) |
risk factors for macular degeneration | smoking, fam hx, cardiovascular dz, obesity and inactivity |
loss of central vision, straight lines appear blurry, wavy or with missing segments, decreased visual acuity and fields, Amsler grid seen with broken or wavy lines | Macular degeneration |
treatment for dry macular degeneration | no known treatment |
treatment for wet macular degeneration | screen with Amsler grid periodically, laser photocoagulation may prevent further visual loss in 50% of cases |
treatment for sudden hearing loss | refer to otolaryngologist ASAP, recovery depends on early diagnosis and treatment |
Weber lateralizes to better ear in __ hearing loss | sensorineural |
