title: Spectral-domain optical coherence tomography following Nd:YAG laser membranotomy in valsalva retinopathy.
abstract: OBJECTIVE
  To describe spectral-domain optical coherence tomography (SD-OCT) findings following Nd:YAG laser membranotomy in premacular hemorrhage due to Valsalva retinopathy.
  
  
  METHODS
  Interventional case series of 7 eyes with premacular hemorrhage due to Valsalva retinopathy. Best-corrected Snellen visual acuity (BCVA) and color fundus photography were obtained before and after the laser treatment. SD-OCT scans were obtained at 1, 3, and 6 months following treatment.
  
  
  RESULTS
  SD-OCT revealed a convex dome-shaped cavity lined by a hyperreflective layer in all cases, which persisted until the end of follow-up. Two patients complained of metamorphopsia, although BCVA improved dramatically in all cases. The site of laser puncture was visible in 2 patients. No abnormality was detected in the underlying retinal layers.
  
  
  CONCLUSIONS
  SD-OCT reveals formation of a premacular cavity following laser puncture for premacular hemorrhage in Valsalva retinopathy, which may persist despite successful drainage of blood. This may later result in metamorphopsia in certain patients.
