Ophthalmology · Retina (Vascular Disorders, Detachment, Macular Disorders, Retinoblastoma)

A 35-year-old male presents with sudden-onset inferior visual field loss. Fundus exam shows a superotemporal horseshoe tear with surrounding subretinal fluid not extending to the macula. The MOST appropriate management is:

  • A Observation with serial fundus photography
  • B Pneumatic retinopexy
  • C Laser retinopexy (demarcation laser) to the borders of the detachment
  • D Pars plana vitrectomy with fluid-air exchange
Correct answer: C. Laser retinopexy (demarcation laser) to the borders of the detachment

Explanation

A subclinical retinal detachment (not extending to within 2 disc diameters of the macula or optic disc) with a causative horseshoe tear can be managed with laser retinopexy (demarcation photocoagulation) around the detachment borders to create a chorioretinal adhesion barrier preventing further progression. Observation risks macula-involving extension. Pneumatic retinopexy requires the detachment to be in the superior 8 clock hours and achieves reattachment via gas tamponade, appropriate for a recent break but less so when fluid is already present without macula involvement. PPV is reserved for complex or macula-involving detachments.
