简介：目的比较急性中心性浆液性脉络膜视网膜病变（CSC）的患侧与对侧眼视网膜频域相干光断层扫描（OCT）的图像特征。方法应用频域OCT对30例（60眼）单眼发病急性CSC患者患侧和对侧眼的黄斑部视网膜显微结构进行检测，比较患侧组与对侧组黄斑中心凹外核层厚度、光感受器层（IS／OS层）、视网膜色素上皮（RPE）形态差异。结果所有30例患者患侧眼均有不同程度黄斑部视网膜浆液性脱离，对侧眼中有4眼（13．3％）存在轻度视网膜浆液性脱离；患侧组黄斑中心凹外核层厚度均值为（95．32±24．87）μm，对侧组为（98．80±14．36）μm，两组差异无统计学意义（t=1．627，P=0．110）。患侧组中IS／OS层厚度均匀一致者12眼（40．0％），对侧组20眼（66．7％）；患侧组IS／OS层厚度均匀一致伴内外节缺损、不均、凸起增厚者共18眼（60．O％），对侧组共10眼（33．3％），差异有统计学意义（X2=4．28，P=0．038）。患侧组中出现RPE异常者有24眼（80．0％），对侧组中有8眼（26．7％），差异有统计学意义（x。=17．143，P=0．000）。结论频域OCT能清晰显示急性CSC患者的细微病理结构改变，单眼发病CSC患者中一部分对侧眼存在IS／OS层和RPE异常，但是其发生率较患侧眼低。（中国眼耳鼻喉科杂志，2013，13：165—167）

简介：低视力患者的常见病因之一是遗传性眼病,最多见的就是小眼球和小角膜,其占低视力病因的10%-20%。小角膜是一种角膜直径在10mm以下的眼球前部异常的遗传疾病,可表现为常染色体显性或隐性遗传,也可见于染色体病。先天性小角膜常合并眼部及全身异常,如小角膜常合并小眼球、虹膜-脉络膜缺损、先天性白内障、眼球震颤和弱视等。小角膜合并白内障患者由于病情复杂,术后易发生继发性青光眼、
