This study compared a novel low-cost solar powered direct ophthalmoscope called the Arclight with a traditional direct ophthalmoscope (TDO). After appropriate training, 25 Malawian eye healthcare workers were asked to examine 12 retinal images placed in a teaching manikin head with both the Arclight ophthalmoscope and a traditional direct ophthalmoscope (Keeler Professional V.2.8). Participants were scored on their ability to identify clinical signs, to make a diagnosis and how long they took to make a diagnosis. They were also asked to score each ophthalmoscope for 'ease of use'. Statistically significant differences were found in favour of the Arclight in the number of clinical signs identified, correct diagnoses made and ease of use. The ophthalmoscopes were equally effective as a screening tool for diabetic retinopathy, and there was no statistically difference in time to diagnosis. The authors conclude that the Arclight offers an easy to use, low cost alternative to the traditional direct ophthalmoscope to meet the demands for screening and diagnosis of visually impairing eye disorders in low-income and middle-income countries.
本研究将一种名为“弧光”的新型低成本太阳能直接检眼镜与传统直接检眼镜（TDO）进行了比较。经过适当培训后，25名马拉维眼科医护人员被要求使用弧光检眼镜和传统直接检眼镜（基勒专业版V.2.8）检查放置在教学人体模型头部的12张视网膜图像。参与者在识别临床体征、做出诊断的能力以及做出诊断所需的时间方面接受评分。他们还被要求对每台检眼镜的“易用性”进行评分。结果发现，在识别的临床体征数量、做出的正确诊断以及易用性方面，弧光检眼镜具有统计学上的显著优势。这两种检眼镜作为糖尿病视网膜病变的筛查工具同样有效，且在诊断时间上没有统计学差异。作者得出结论，弧光检眼镜为传统直接检眼镜提供了一种易于使用、低成本的替代方案，以满足低收入和中等收入国家对筛查和诊断视力损害性眼病的需求。
