To describe spectral-domain optical coherence tomography (SD-OCT) findings following Nd:YAG laser membranotomy in premacular hemorrhage due to Valsalva retinopathy.
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.
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.
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.
描述在因瓦氏视网膜病变导致的黄斑前出血行Nd:YAG激光膜切开术后的频域光学相干断层扫描（SD-OCT）表现。
对7例因瓦氏视网膜病变导致黄斑前出血的患者进行介入性病例系列研究。在激光治疗前后分别测量最佳矫正视力（BCVA）并进行彩色眼底照相。在治疗后1个月、3个月和6个月进行SD-OCT扫描。
SD-OCT显示所有病例中均有一个由高反射层衬里的凸形穹窿状腔隙，该腔隙一直持续到随访结束。2例患者主诉视物变形，尽管所有病例的BCVA均显著改善。2例患者可见激光穿刺部位。视网膜深层未检测到异常。
SD-OCT显示在因瓦氏视网膜病变导致黄斑前出血行激光穿刺后形成黄斑前腔隙，尽管血液已成功引流，但该腔隙可能持续存在。这可能会在某些患者中导致后期视物变形。
