Ophthalmology · Glaucoma: blebitis

Sample item

Three years after trabeculectomy, a patient has a red eye with a milky white bleb and anterior chamber reaction, but a clear vitreous. This is:

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

The answer and the reasoning

A. Blebitis

Blebitis is infection confined to the bleb with a milky bleb and mild anterior chamber activity, treated with intensive topical antibiotics. If the vitreous is involved it becomes bleb-related endophthalmitis, an emergency. Thin avascular blebs after antimetabolite use have the highest risk.

Option by option

  • A. Blebitis (correct)

    Correct. Infection limited to the bleb is blebitis.

  • B. Bleb-related endophthalmitis

    Endophthalmitis would show vitreous involvement.

  • C. Over-filtration

    Over-filtration gives hypotony and a flat chamber.

  • D. Encapsulated bleb

    An encapsulated bleb is a high, tense bleb with raised IOP.
