BACKGROUND/PURPOSE: Fungal endophthalmitis caused by dissemination from extraocular fungal infections has been reported to vary between 9% and 45%. However, recent clinical experience disagrees with that. This study is an investigation of patients in an inner city teaching hospital, the risks associated with endogenous fungal endophthalmitis, and this incidence.
All ophthalmology consultations between February 1995 and August 2000 that might be associated with disseminated fungal infection were examined in a prospective manner. Patients were excluded if there was no evidence of a positive fungal culture from any site at any time. Visual symptoms were recorded along with ophthalmologic and systemic examination features. Information was gathered, including the identity of cultured organisms, the sites from which the organisms were obtained, and the patients' disposition.
During this interval, 170 consultation requests contained the words "endophthalmitis" or "retinitis" and/or indicated concern about disseminated fungal infections. Extraocular fungal infections were found in 114 patients, but only 82 of them had evidence of systemic dissemination. Some patients had more than one organism. The following are listed in decreasing frequency of occurrence: Candida albicans, Torulopsis glabrata, Candida tropicalis, Candida parapsilosis, Candida krusei, Aspergillus niger, and others. Only two patients had evidence of chorioretinitis and progressed to fungal endophthalmitis.
Endophthalmitis was rare among these patients with known fungal infections. Less than 2% had any related ophthalmic manifestations. Nevertheless, since treatment can save vision, evidence of intraocular infection should be sought as eagerly as before.
背景/目的:据报道,由眼外真菌感染播散引起的真菌性眼内炎发生率在9%至45%之间。然而,最近的临床经验对此并不认同。本研究对一家市中心教学医院的患者进行调查,以了解与内源性真菌性眼内炎相关的风险及发生率。
对1995年2月至2000年8月期间所有可能与播散性真菌感染相关的眼科会诊进行前瞻性检查。如果患者在任何时候任何部位均无真菌培养阳性的证据,则将其排除。记录视觉症状以及眼科和全身检查特征。收集的信息包括培养出的微生物种类、微生物的获取部位以及患者的转归情况。
在此期间,170份会诊申请中包含“眼内炎”或“视网膜炎”字样和/或表明对播散性真菌感染的担忧。114例患者发现有眼外真菌感染,但其中只有82例有全身播散的证据。有些患者感染了不止一种微生物。按出现频率从高到低依次列出如下:白色念珠菌、光滑假丝酵母菌、热带念珠菌、近平滑念珠菌、克柔念珠菌、黑曲霉等。只有2例有脉络膜视网膜炎的证据并进展为真菌性眼内炎。
在这些已知真菌感染的患者中,眼内炎很罕见。不到2%的患者有任何相关的眼科表现。然而,由于治疗可挽救视力,仍应像以前一样积极寻找眼内感染的证据。
