Iris microhemangiomas (IM) are benign proliferations of small, twisted blood vessels along the pupillary margin. They are usually bilateral and appear to be developmental in nature. IMs most commonly occur in patients with myotonic dystrophy and adult-onset diabetes mellitus, but have also been associated with respiratory disease, congential heart disease, and central retinal vein occlusion. Additionally, they may be found in individuals without obvious ocular or systemic abnormality. The etiology remains obscure. In this report, illustrative cases are followed by a brief discussion outlining typical clinical manifestations, etiological considerations, and possible implications.
虹膜微血管瘤（IM）是沿瞳孔边缘的小而扭曲的血管的良性增生。它们通常是双侧的，似乎本质上是发育性的。IM最常见于强直性肌营养不良和成人发病的糖尿病患者，但也与呼吸系统疾病、先天性心脏病和视网膜中央静脉阻塞有关。此外，它们也可能在没有明显眼部或全身异常的个体中发现。病因仍不清楚。在本报告中，通过病例说明之后进行简短讨论，概述典型的临床表现、病因学考虑及可能的影响。
