BACKGROUND AND OBJECTIVE: To describe spectral-domain optical coherence tomography (SD-OCT) findings following Nd:YAG laser membranotomy in premacular hemorrhage due to Valsalva retinopathy. PATIENTS AND 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. CONCLUSION: 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. Copyright 2011, SLACK Incorporated.
