To demonstrate the plane of premacular hemorrhage in Valsalva retinopathy with optical coherence tomography
Observational case report
Two young men with Valsalva stress-related premacular hemorrhage were evaluated by OCT scans, taken just above the level of sedimented blood.
In both cases, OCT demonstrated two distinct membranes: a highly reflective band immediately above the premacular hemorrhage, corresponding to the internal limiting membrane, and an overlying patchy membrane with low optical reflectivity consistent with posterior hyaloid.
OCT supported the clinical impression that the plane of premacular hemorrhage in Valsalva retinopathy is probably under ILM. Larger case studies are required to confirm this finding.
通过光学相干断层扫描显示瓦尔萨尔瓦视网膜病变黄斑前出血的层面
观察性病例报告
对两名因瓦尔萨尔瓦压力相关黄斑前出血的年轻男性进行光学相干断层扫描评估，扫描位置在沉积血液水平上方。
在两例病例中，光学相干断层扫描均显示出两个不同的膜：黄斑前出血正上方的高反射带，对应于内界膜；以及上方覆盖的光学反射率低的斑片状膜，与后玻璃体膜一致。
光学相干断层扫描支持了临床印象，即瓦尔萨尔瓦视网膜病变黄斑前出血的层面可能在内界膜之下。需要更大规模的病例研究来证实这一发现。
