目的探讨先天性无虹膜患者相关眼部疾病的临床特点。方法对我院所诊治的先天性无虹膜患者8例进行视力、裂隙灯、眼底及眼压检查,并记录检查结果进行分析。结果所有患者裂隙灯检查虹膜完全缺如,可见晶状体赤道部和悬韧带,眼球震颤。4例患者晶状体不同程度混浊,2例晶状体向上方不全脱位。1例患者角膜缘新生血管,下方角膜浅层混浊。3例患者眼底黄斑区光反射消失。4例患者手术后视力提高不理想。结论先天性无虹膜不是一类独立的眼科疾病,常合并白内障、晶状体脱位,黄斑发育不良等其他眼部疾患和全身疾病。
Objective To investigate the clinical features of related eye diseases in patients with congenital absence of iris.
