1. Preservation of donor corneas:
a. McCarey-Kaufman preserves endothelial viability up
to 6 days
b. moist chamber stored corneas should be transplanted
within 48 hours
c. TC 199 is a component of McCarey-Kaufman medium
d. organ culture allows preservation up to one month
e. McCarey-Kaufman eyes should be stored at 10C
2. Mooren's ulcer:
a. about 2.5% of cases are bilateral
b. is associated with much pain
c. satisfactory results have occasionally been obtained
by resection of the limbal conjunctiva adjacent
tot he
lesion
d. the most rapid movement of the ulcer is centrally with
the leading edge de-epithelialized and undermined
e. is associated with a better prognosis in patients below
their fourth decade of life
3. Band keratopathy can be seen in:
a. adult rheumatoid arthritis
b. sarcoidosis
c. iridocyclitis
d. vitamin D toxicity
e. juvenile rheumatoid arthritis
4. Hassal-Henle warts are associated with:
a. appearance in the central cornea
b. thinning of endothelial cytoplasm near wart
c. fissures over and into substance of wart
d. mouths of fissures beneath endothelial cells
e. there are structural differences from guttae located
elsewhere
5. Corneal involvement in leprosy include:
a. superficial punctate keratitis
b. disciform keratitis
c. pannus
d. deep interstitial keratitis
e. neurotrophic keratopathy
6. Stargardt's disease:
a. is characterized by nyctalopia
b. peripheral fields and colour vision are normal
c. patients present in second and third decade of life
d. has an autosomal recessive as well as dominant mode
of inheritance
e. is characterized by an abnormal EOG early in the
course of the disease.
7. The following are associated with congenital cataracts:
a. incontinentia pigmenti
b. intrauterine hypoxia
c. Lowe's syndrome
d. Patau's syndrome
e. Rubenstein-Taybi syndrome
8. The ocular complications of bone marrow transplantation
include:
a. keratoconjunctivitis sicca
b. cataracts
c. herpes simplex infections
d. cicatricial lagophthalmos
e. corneal keratinization
9. Congenital nystagmus:
a. is binocular and uniplanar
b. is dampened with fixation effort
c. is usually horizontal, but may be vertical, circular,
pendular or jerky
d. may be alleviated with the use of base-in prism glasses
e. may be treated surgically with he Kestenbaum
procedure
10. Regard topical corticosteroids:
a. dexamethasone phosphate does not penetrate the
uninflammed cornea whereas dexamethasone alcohol
does
b. topical steroid solutions penetrate the cornea better
than steroid suspensions
c. steroid eye cream achieves a higher concentration in
the eye than drops due to a longer contact time
d. topical steroids reduce corneal polymorphonuclear
leukocyte invasion better than subconjunctival
injections of steroid
e. sudden cessation of topical steroids in corneal
inflammation can cause a rebound nercotizing
inflammation.
