急性旁中央中层黄斑病变(Paracentral acute middle maculopathy, PAMM)是Sarraf等人首先通过光学相干断层扫描发现,是位于视网膜中部的中间毛细血管丛(ICP)水平缺血的结果。已经确定了各种病因,包括局部血管闭塞性疾病,如视网膜动脉闭塞和视网膜中央静脉闭塞(CRVO),以及全身性疾病,如糖尿病视网膜病变、远达性视网膜病变和镰状细胞视网膜病变。此外,一些特定药物的使用或代谢紊乱,如高同型半胱氨酸血症,也被认为是可能的致病因素。本文讲述1例视力、体征治疗后均明显好转的PAMM。Paracentral acute middle maculopathy (PAMM) is a tomographic finding firstly described by Sarraf et al. as the results of ischemia at the level of the intermediate capillary plexus (ICP) located in the middle retina. Various aetiologies have been identified which include local vascular occlusive disorders such as retinal arterial occlusion and central retinal vein occlusion (CRVO), as well as systemic diseases such as diabetic retinopathy, purtscher retinopathy and sickle cell retinopathy. This article describes a case of PAMM, whose visual acuity and physical signs improved significantly after treatment.
