,dry eye syndrome - --CORRECT ANSWER--abnormalities in tear film.
tear film is formed with each blink and this limits evaporation.

insufficiency. Sjogrens or other disease
evaoprative deficient--meibomian gland dysfunction, poor eyelid closure,
inadequate blinking, ocular rosacea
presentation/PE dry eye - --CORRECT ANSWER--dryness, foreign body
sensation, burning, stinging, ocular fatigue, light sensitive. some have reflexive
hypersecretion because of corneal irritation
meds causing dry eyes: anticholinergic, alpha blocker (flomax), anti HTN, oral
corticosteroids, vitamins, autoimmune disease
Assess: visual acuity, fluorescein dye , cranial nerve function
diagnostics of dry eye - --CORRECT ANSWER--schirmer test (filter paper to
measure tear production)
pharm treatment dry eye - --CORRECT ANSWER--artificial tears, ointments,
preservative free if needed

use pen light to look at nares, assess lymph nodes,
diagnostics nasal polyps - --CORRECT ANSWER--endoscopic eval and biopsy is
gold standard
CBC
sinus x-ray, may need CT/MRI to assess bone involvement
