摘要
目的:探讨黄斑部视网膜出血的出血原因、部位和程度,并分析对中心视力的影响。方法:对85例黄斑部视网膜出血患者的临床资料,结合FFA检查对发病后中心视力、出血部位、面积、程度进行回顾性分析。结果:85例黄斑部视网膜出血患者发病时中心视力损害严重,依出血部位分为视网膜前出血、视网膜内出血、视网膜下出血、混合性出血,依出血程度分为轻度、中度、重度和巨大出血。结论:各种原因导致黄斑部视网膜出血影响中心视力重要因素是出血遮蔽,出血面积和部位影响出血的吸收和视功能的恢复。
AIM： To observe the clinical causes and the area and degree of macular hemorrhages based on fundus fluorescein angiography （FFA）. METHODS： Eighty-five patients （85 eyes） with macular hemorrhages were proved by FFA. The clinical feature and appearance were observed retrospectively. RESULTS： there are three groups by hemorrhage location： 26 eyes of submacular hemorrhage, 43 eyes of intramacular hemorrhage and 16 eyes of epiretinal macular hemorrhage. Only 6 eyes had both mixture epiretinal macular hemorrhage and intramacular hemorrhage and 7 eyes had mixture submacular hemorrhage and intramacular hemorrhage. According to the area of hemorrhage classify there were four degrees： light or superficial hemorrhage, middle hemorrhage, higher hemorrhage and great or marked degree differently. CONCLUSION： Various causes lead to macular hemorrhage. The majority of patients experience severe vision loss, particularly subfoveal hemorrhage obstructing. The area degree and location of blood also influence the visual recovery.
