TELC, tropical endemic limbo-conjunctivitis, is a keratoconjunctivitis seen more frequently in dry intertropical settings than humid ones. We aim to determine the epidemiologic and clinical profile of this condition in a city with a humid equatorial climate.
During first third of 2014, we conducted a cross-sectional descriptive study in schools. Included were children aged 3-15 years who received parental consent. The selection was conducted in two steps. After an initial examination of children within the schools, the diagnosis was then confirmed by a complete ophthalmologic examination carried out in the hospital. For ethical clearance, the study received all necessary authorizations. The data were analyzed using the CSPro version 4.0 software in French and the comparison test used was χ with a confidence limit of 95 %.
Out of 353 students examined, 129 were referred to the Yaoundé central hospital, among which 82 (23.2 %) were confirmed with TELC. The median age of the children diagnosed with TELC was 8.24+0.6 years. Boys (57.3 %) were affected more than girls. The age range of 6-12 years (64.6 %) was the most represented. A recrudescence of the attacks was observed during the dry season (93 %) of cases. Dust (49 %) and sun exposure (43 %) were aggravating factors.
The prevalence of TELC observed in school in this study is significant.
热带地方性边缘性角结膜炎（TELC）是一种角结膜炎，在热带干旱地区比湿润地区更为常见。我们旨在确定在赤道湿润气候城市中这种疾病的流行病学和临床特征。
2014年第一季度，我们在学校开展了一项横断面描述性研究。纳入的是获得家长同意的3至15岁儿童。选择过程分两步进行。在学校对儿童进行初步检查后，然后在医院进行全面眼科检查以确诊。为获得伦理批准，该研究获得了所有必要的授权。数据使用法语版CSPro 4.0软件进行分析，使用的比较检验是置信度为95%的χ检验。
在接受检查的353名学生中，129名被转诊至雅温得中心医院，其中82名（23.2%）被确诊为TELC。确诊为TELC的儿童中位年龄为8.24 + 0.6岁。男孩（57.3%）比女孩受影响更大。6至12岁年龄组（64.6%）占比最大。在病例的旱季（93%）观察到病情复发。灰尘（49%）和阳光照射（43%）是加重因素。
本研究在学校观察到的TELC患病率较高。
