Ophthalmology · Retina: proliferative vitreoretinopathy

Sample item

Two months after a repair of rhegmatogenous detachment, the retina redetaches with star folds and fixed retinal creases, and no new break. What is the process?

AA new break from posterior vitreous detachmentBChoroidal effusionCProliferative vitreoretinopathyDRetinoschisis

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

The answer and the reasoning

C. Proliferative vitreoretinopathy

Proliferative vitreoretinopathy is contraction of cellular membranes on the retinal surfaces after detachment, the commonest cause of surgical failure. Treatment is vitrectomy with membrane peeling and tamponade. A new break would show a tear, and effusion would produce smooth detachment.

Option by option

A. A new break from posterior vitreous detachment
A new break would show a tear, while this case has no new break.
B. Choroidal effusion
A choroidal effusion causes smooth elevations, not star folds.
C. Proliferative vitreoretinopathy (correct)
Correct. Membranes contract and fix the retina in folds.
D. Retinoschisis
Retinoschisis is a split within the retina and is not a redetachment.
