You observe epithelial microcysts D. 7 microns
on a contact lens patient
and have discontinued the
patient's lens wear. Upon
rechecking the patient in
the next 2 to 4 weeks, you
observe:
A. More microcysts
B. Less microcysts
C. No microcysts
D. No change the microcysts
will always be there
5. Pinpoint lesions on the
cornea that stain with
flourescein are of-ten
indicative of:
A. Superficial punctuate
keratitis
B. Microbial keratitis
C. Superior arcuate
epithelial le-sions
D. Superior limbic
keratoconjunc-tivitis
6. The thickness of the tear film
is:
A. 0.007 microns
B. 0.07 microns
C. 0.7 microns

More microcysts micron thick and the mucin layer 0.2 to0.5
microns thick.
scontinuing lens wear increases the epithelium's
metabolic function. The deeper layers or disorganized
epithelial tissues are brought to the surface,
causing more microcysts to appear. Complete
resolution may take several months.
