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

The answer and the reasoning

C. Cyanoacrylate glue with bandage contact lens

Small perforations (up to about 2 to 3 mm) can be sealed with cyanoacrylate tissue adhesive and a bandage lens, followed by antibiotics and aqueous suppressants. Larger perforations need patch grafts or keratoplasty. Glue is also useful in descemetoceles.

Option by option

  • A. Immediate penetrating keratoplasty in all cases

    Keratoplasty is reserved for large defects or failed glue.

  • B. Patching and observation

    Observation risks endophthalmitis.

  • C. Cyanoacrylate glue with bandage contact lens (correct)

    Correct. Glue and a bandage lens seal a small perforation.

  • D. Evisceration

    Evisceration is for a destroyed eye.
