Ophthalmology · Glaucoma: trabeculectomy

Sample item

Which adjunct is commonly applied during trabeculectomy to reduce scarring of the filtering bleb?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Mitomycin C

Mitomycin C or 5-fluorouracil inhibits fibroblast proliferation and so lowers the rate of bleb failure. A risk of antimetabolite use is thin avascular blebs and late bleb leaks or infection.

Option by option

  • A. Mitomycin C (correct)

    Atropine is a cycloplegic used in malignant glaucoma.

  • C. Timolol

    Timolol is a beta-blocker.

  • D. Pilocarpine

    Pilocarpine is a miotic antiglaucoma drug.
