患者女,60岁.因左眼视力下降15d于2012年7月18日来我院眼科就诊.患者无糖尿病、高血压、放射线接触史及特殊家族史.全身检查未见明显异常.眼科检查:右眼视力0.6,左眼视力0.3,均不能矫正.右眼眼压16 mmHg(1 mmHg=0.133 kPa),左眼眼压15 mmHg.角膜、晶状体、玻璃体均透明.右眼眼底未见异常.左眼黄斑中心凹可见一淡黄色病灶.黄斑区轻度水肿,拱环颞上可见约1个视盘直径(DD)大小半环形硬性渗出灶(图1).荧光素眼底血管造影(FFA)检查结果显示,左眼黄斑拱环颞侧及颞上方毛细血管扩张,颞上方拱环结构破坏.邻近的部分小血管囊样扩张,呈瘤样强荧光.随造影时间延长,病灶区荧光渗漏.晚期病灶区局限性强荧光(图2).诊断:左眼特发性黄斑中心凹旁毛细血管扩张症(IPT).给予黄斑拱环颞上方局灶性激光光凝治疗.光斑直径100 μm,曝光时间0.1s,功率125～150 mW,21点,Ⅰ～Ⅱ级反应.2012年10月14日复诊时左眼视力0.4,拱环颞上硬性渗出灶较前缩小.未行FFA检查.
