Sample item

In the WHO simplified grading of trachoma, which sign indicates a need for lid surgery?

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

The answer and the reasoning

A. TT, trachomatous trichiasis

The WHO scheme includes TF, TI, TS, TT and CO (corneal opacity). Trachomatous trichiasis, defined as at least one lash touching the globe, needs surgery such as bilamellar tarsal rotation. TF and TI need antibiotic treatment.

Option by option

  • A. TT, trachomatous trichiasis (correct)

    Correct. Trichiasis is managed by surgery to prevent blindness.

  • B. TI, trachomatous intense inflammation

    TI is the active intense inflammatory stage treated with antibiotics.

  • C. TF, trachomatous follicular inflammation

    TF is treated with azithromycin and face washing.

  • D. TS, trachomatous scarring

    TS signifies tarsal scars and does not itself need surgery.
