Abstract

PURPOSE

To characterize confocal scan features of keratic precipitates (KPs) in Fuchs heterochromic iridocyclitis.

METHODS

Confocal scans of KPs in patients with Fuchs uveitis were performed. Polymerase chain reaction technique of aqueous for herpes simplex, herpes zoster, Toxoplasma, cytomegalovirus, and rubella was performed for 4 patients.

RESULTS

Confocal scan was performed in 40 eyes of 34 patients [18 males and 16 females, mean age 30.7 +/- 10.5 years (range 18-57 years)]. Fuchs heterochromic iridocyclitis was bilateral in 6 and unilateral in 28 patients. All eyes had KPs: globular KPs were found in 34 eyes, infiltrating and dendritiform in 31 eyes, stippled in 27 eyes, and cruciform in 19 eyes. Polymerase chain reaction of aqueous specimens for the above-mentioned infectious agents was negative in 4 eyes of 4 individuals who had infiltrating and dendritiform KPs on confocal scan, with no other concurrent disorder.

CONCLUSIONS

Confocal features of KPs in Fuchs uveitis are diverse. The presence of dendritiform and infiltrating KPs on confocal scan may not be suggestive of an infectious etiology.

摘要

目的

描述 Fuchs 异色性虹膜睫状体炎的角膜后沉着物（KP）的共焦扫描特征。

方法

对 Fuchs 葡萄膜炎患者的 KP 进行共焦扫描。对 4 例患者进行了单纯疱疹、带状疱疹、弓形虫、巨细胞病毒和风疹的水聚合酶链反应技术。

结果

对 34 例患者的 40 只眼（男性 18 例，女性 16 例，平均年龄 30.7 +/- 10.5 岁[18-57 岁]）进行了共焦扫描。6 例为双侧 Fuchs 异色性虹膜睫状体炎，28 例为单侧。所有眼睛均有 KP：34 只眼有球形 KP，31 只眼有浸润性和树突状 KP，27 只眼有斑点状 KP，19 只眼有十字形 KP。4 例共焦扫描显示浸润性和树突状 KP 的患者的水样标本聚合酶链反应对上述感染因子均为阴性，无其他合并症。
