MCQ MAHE 2000 Ophthalmology Answer 01
The Correct Answer is A- Most cases of primary congenital glaucoma are sporadic in occurrence. However, evidence exists suggesting that the disease may be transmitted through an autosomal recessive pattern, with variable penetrance, or a polygenic inheritance pattern.
- CYP1B1, the gene encoding cytochrome P4501B1, is associated with primary congenital glaucoma. GLC3B located on band 1p36 and GLC3C located on band 14q24.3 are loci that are linked to primary congenital glaucoma, but the genes are unknown.
- The incidence of CYP1B1 in familial cases is 93% in Saudi Arabia, 50% in Brazil, and 20-30% in ethnically mixed populations, and its incidence in nonfamilial (simplex) cases is 10-15%.
The classic triad of manifestations, any one of which should arouse suspicion of glaucoma in an infant or young child, includes epiphora, photophobia, and blepharospasm.
