我们的目的是评估未经眼科培训的个人使用智能手机和低成本眼前节成像适配器（“EyeGo”原型）快速捕获高质量角膜图像的能力。七名志愿者使用配备 EyeGo 适配器的 iPhone 5S 拍摄了印度瓦尔尼 751 名高中生的 1,502 个眼前节。主要结果指标是角膜和眼前节的中位照片质量（在急诊科 [FOTO-ED] 研究中验证眼底摄影与检眼镜试验结果；1-5 等级；5，最佳）以及拍摄每张照片所需的时间。志愿者接受了关于使用智能手机的熟悉程度（1-5级；5，非常舒适）和评估眼睛问题的舒适度（1-5级；5，非常舒适）的调查。使用图像质量（低质量：<4；高质量：≥4）作为因变量，以年龄、使用智能手机的舒适度以及评估眼睛问题的舒适度作为自变量进行二项式逻辑回归。七名志愿者中的六名捕获了高质量（中值≥4/5）的图像，所有被筛查的眼睛每只眼睛的中值时间≤25秒。七名志愿者中的四名表现出获取照片的时间显着减少（P1=0.01、P5=0.01、P6=0.01 和 P7=0.01），七名志愿者中的三名表现出在前 100 只眼睛和最后 100 只眼睛筛查之间照片质量的显着改善（P1<0.001、P2<0.001 和 P6<0.01）。使用智能手机的自我报告舒适度（优势比 [OR] =1.25；95% CI =1.13 至 1.39）和诊断眼部疾病的自我报告舒适度（OR =1.17；95% CI =1.07 至 1.29）与拍摄高质量图像的能力显着相关（≥4/5）。年轻年龄与拍摄高质量图像的能力之间没有显着关联。没有接受过眼科培训的人能够使用带有成像适配器的智能手机快速捕捉眼前节的高质量放大视图。
We aimed at evaluating the ability of individuals without ophthalmologic training to quickly capture high-quality images of the cornea by using a smartphone and low-cost anterior segment imaging adapter (the “EyeGo” prototype). Seven volunteers photographed 1,502 anterior segments from 751 high school students in Varni, India, by using an iPhone 5S with an attached EyeGo adapter. Primary outcome measures were median photograph quality of the cornea and anterior segment of the eye (validated Fundus Photography vs Ophthalmoscopy Trial Outcomes in the Emergency Department [FOTO-ED] study; 1–5 scale; 5, best) and the time required to take each photograph. Volunteers were surveyed on their familiarity with using a smartphone (1–5 scale; 5, very comfortable) and comfort in assessing problems with the eye (1–5 scale; 5, very comfortable). Binomial logistic regression was performed using image quality (low quality: <4; high quality: ≥4) as the dependent variable and age, comfort using a smartphone, and comfort in assessing problems with the eye as independent variables. Six of the seven volunteers captured high-quality (median ≥4/5) images with a median time of ≤25 seconds per eye for all the eyes screened. Four of the seven volunteers demonstrated significant reductions in time to acquire photographs (P1=0.01, P5=0.01, P6=0.01, and P7=0.01), and three of the seven volunteers demonstrated significant improvements in the quality of photographs between the first 100 and last 100 eyes screened (P1<0.001, P2<0.001, and P6<0.01). Self-reported comfort using a smartphone (odds ratio [OR] =1.25; 95% CI =1.13 to 1.39) and self-reported comfort diagnosing eye conditions (OR =1.17; 95% CI =1.07 to 1.29) were significantly associated with an ability to take a high-quality image (≥4/5). There was a nonsignificant association between younger age and ability to take a high-quality image. Individuals without ophthalmic training were able to quickly capture a high-quality magnified view of the anterior segment of the eye by using a smartphone with an attached imaging adapter.
