Ophthalmology · Retina: rhegmatogenous detachment

Sample item

A myopic man reports flashes, a shower of floaters and then a curtain across his vision. What is the likely diagnosis?

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

The answer and the reasoning

B. Rhegmatogenous retinal detachment

Vitreous traction on the retina causes photopsia, and a tear then lets liquefied vitreous enter the subretinal space. Urgent repair by retinopexy, scleral buckle or vitrectomy is needed.

Option by option

  • A. Central retinal artery occlusion

    Artery occlusion causes sudden painless total loss.

  • B. Rhegmatogenous retinal detachment (correct)

    Correct. Photopsia, floaters and a curtain are classic.

  • C. Acute angle closure

    Angle closure is painful with halos.

  • D. Optic neuritis

    Optic neuritis has pain on movement and central loss.
