BATES HEENT Chapter 7 Questions with
Correct Answers
sudden, painless, unilateral vision loss
vitreous hemorrhage from diabetes or trauma, macular degeneration, retinal detachment,
retinal vein occlusion, central artery occlusion
hyperopia (farsightedness) and presbyopia
both are indicated by difficulty with close work
myopia
nearsightedness
painless bilateral vision loss
medications that change refraction such as cholinergics, anticholinergics, and steroids
painful unilateral vision loss
causes are usually in corna or anterior chamber: cornal ulcer, uveitis, traumatic hyphema,
acute glaucoma, optic neuritis from MS
gradual bilateral vision loss
cataracts, macular degeneration
slow central vision loss
nuclear cataract, macular degeneration
peripheral vision loss
adbance open-angle glaucoma
, one-sided loss
in hemianopsia and quadrantic defects
moving specks or strands
vitreous floaters
fixed defects in vision (scotomas)
lesion in the retina or visual pathway
flashing lights or new vitreous floaters in vision
detatchment of vitreous from retina; prompt eye consultation is indicated
Diplopia
lesion in brainstem or cerebellum, weakness or paralysis of extraocular muscles (horizontal
diplopia from palsy of CNIII or VI, or vertical diplopia from palsy of CNIII or IV)
Diplopiain one eye with other closed
problem with cornea or lens
can hearing loss be congenital?
Yes. from single gene mutations
sensorineural hearing loss
particular trouble understanding speech, often complaining that others mumble; noisy
environments make hearing worse
noisy environments may help hearing with
conductive hearing loss
