Retinal arterial macroaneurysms are ectatic modifications of the arterial wall. They are a relatively uncommon condition that can threaten visual function by pre- or subretinal hemorrhage if rupture or massive macular exudation occurs.
We report a case of a 59-year-old patient with arterial hypertension who presented an arterial macroaneurysm complicated by premacular hemorrhage. We performed Nd: YAG laser photodisruption, which resulted in drainage of preretinal blood, with complete hemorrhage regression and visual recovery.
Retinal macroaneurysms are acquired malformations, often isolated and located in a temporal artery. Their progression is unpredictable, evolving toward spontaneous occlusion, occurrence of chronic exudative retinopathy, or hemorrhagic complications by fissuration or rupture of the arterial wall. Through this observation, the authors discuss the value of YAG laser photodisruption for preretinal hemorrhage caused by retinal macroaneurysm.
视网膜动脉大动脉瘤是动脉壁的扩张性改变。它们是一种相对罕见的病症，如果发生破裂或大量黄斑渗出，可通过视网膜前或视网膜下出血威胁视功能。
我们报告一例59岁高血压患者，其患有动脉大动脉瘤并伴有黄斑前出血。我们进行了Nd:YAG激光光凝术，导致视网膜前血液引流，出血完全消退且视力恢复。
视网膜大动脉瘤是后天性畸形，通常为孤立性，位于颞侧动脉。其进展不可预测，可发展为自发闭塞、慢性渗出性视网膜病变，或因动脉壁裂开或破裂而出现出血性并发症。通过本观察，作者讨论了YAG激光光凝术对视网膜大动脉瘤所致视网膜前出血的价值。
