Ophthalmology · Lens: phacomorphic glaucoma

Sample item

An elderly woman with a swollen white cataract has acute eye pain, a shallow anterior chamber and IOP of 50 mmHg. What is the definitive treatment?

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

The answer and the reasoning

D. Cataract extraction after IOP control

In phacomorphic glaucoma the intumescent lens causes secondary angle closure by pupillary block. After reducing the IOP medically, removing the lens cures the problem.

Option by option

  • A. Pilocarpine alone

    Pilocarpine can worsen pupillary block.

  • B. Trabeculectomy only

    Trabeculectomy ignores the mechanism and is riskier.

  • C. Prolonged observation

    Delay risks permanent optic nerve damage.

  • D. Cataract extraction after IOP control (correct)

    Correct. The lens is the cause and needs to be removed.
