The aim of the study was to determine the rates of trachoma in Aboriginal communities and to compare clinical assessment with photographic assessment for the presence of signs of trachoma.
Five Aboriginal communities in the Katherine region of the Northern Territory, Australia, were assessed for the presence of trachoma. Trachoma was diagnosed by clinical eye examination using a fine grading based on the World Health Organization (WHO) simplified grading system. Photographs were taken of the left eye of every person and graded using the fine grading system. The clinical assessment was compared with the photographic assessment for each person using the fine grading system.
A total of 1316 people out of 1545 (85.2%) were screened for trachoma from five communities, with 1254 photographs being compared with clinical assessment scores. The overall prevalence of active trachoma was greater than 10% across the five communities, and greater than 20% in two communities.
Active trachoma in young people and scarring in older people remain as problems in Aboriginal communities. Photographic assessment is a useful technique, but in comparison with clinical assessment it can result in overestimation of scoring for trachoma for inflammation.
本研究旨在确定原住民社区沙眼的发病率，并比较临床评估与摄影评估在沙眼体征存在方面的差异。
对澳大利亚北领地凯瑟琳地区的五个原住民社区进行沙眼评估。采用基于世界卫生组织（WHO）简化分级系统的精细分级，通过临床眼部检查诊断沙眼。对每个人的左眼进行拍照，并使用精细分级系统进行分级。使用精细分级系统将每个人的临床评估与摄影评估进行比较。
五个社区共筛查了1545人中的1316人（85.2%）是否患有沙眼，将1254张照片与临床评估分数进行了比较。五个社区活动性沙眼的总体患病率超过10%，两个社区超过20%。
年轻人中的活动性沙眼和老年人中的瘢痕形成仍是原住民社区存在的问题。摄影评估是一种有用的技术，但与临床评估相比，它可能会导致对沙眼炎症评分的高估。
