Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
This is a retrospective interventional case report.
A 43-year-old healthy male presented with sudden vision loss in his left eye, reporting a visual acuity of 6/120 since the previous evening. Fundus examination revealed a PMH characterized by a "double-ring sign" accompanied by diffuse retinal hemorrhages. Optical coherence tomography confirmed that the hemorrhage was located in the sub-ILM space. The patient underwent two sessions of YAG laser membranotomy, utilizing energies of 2.5 mJ and 5 mJ, which successfully facilitated drainage of fresh hemorrhage from the sub-ILM space to the subhyaloid space and vitreous cavity. However, the presence of residual coagulated blood over the fovea resulted in persistent visual impairment, necessitating a subsequent pars plana vitrectomy (PPV). The PPV, in conjunction with internal limiting membrane peeling, effectively removed the remaining blood in front of the fovea and restored the visual acuity. By postoperative day 3, the patient experienced a significant improvement in visual acuity, measuring 6/8.
This case underscores the importance of thorough clinical examination and precise diagnostic techniques in the individualized management of PMHs, which is essential for achieving optimal visual outcomes.
黄斑前出血(PMH)的准确定位至关重要,因为根据出血位于玻璃体凝胶内、玻璃膜下间隙还是内界膜(ILM)下方,治疗策略会有显著差异。本报告概述了一名被诊断为疑似瓦尔萨尔瓦视网膜病变继发PMH患者的临床特征、诊断结果及治疗效果。
这是一篇回顾性介入病例报告。
一名43岁健康男性因左眼突然视力丧失就诊,自述自前一晚起视力为6/120。眼底检查发现一处具有“双环征”且伴有弥漫性视网膜出血的PMH。光学相干断层扫描证实出血位于ILM下间隙。患者接受了两次YAG激光膜切开术,分别使用2.5 mJ和5 mJ的能量,成功促使新鲜出血从ILM下间隙引流至玻璃膜下间隙和玻璃体腔。然而,黄斑区残留的凝固血液导致视力持续受损,因此需要随后进行玻璃体切割术(PPV)。PPV联合内界膜剥除术有效清除了黄斑前剩余的血液并恢复了视力。术后第3天,患者视力显著改善,达到6/8。
该病例强调了全面临床检查和精确诊断技术在PMH个体化管理中的重要性,这对于实现最佳视力预后至关重要。
