在太平洋岛国瓦努阿图进行概念验证研究，以测试使用一体化便携式视网膜照相机筛查糖尿病视网膜病变的可行性，瓦努阿图糖尿病及其相关并发症的发病率很高，而且眼科医生缺乏。从2020年2月10日至2020年2月28日，来自瓦努阿图三个岛屿的49名糖尿病患者被招募参加这项研究。获得人口统计学、基本健康数据和视网膜照相。使用非散瞳的手持式相机（Volk Pictor Plus）。11名参与者（24%）患有糖尿病视网膜病变。我们的因变量具有中等程度的高评分者间可靠性：转诊状态（κ = 0.62，95% CI 0.42-0.83）、视网膜病变严重程度（κ = 0.76，95% CI 0.55-0.96）和临床显著性黄斑水肿（κ = 0.50，95% CI 0.25-0.74）。我们的研究证实，便携式手持摄像机可用于获得足够质量的糖尿病视网膜病变筛查视网膜图像，即使在资源有限的环境，如瓦努阿图。在该队列中，瓦努阿图的糖尿病视网膜病变患病率相对较高（24%）。
Proof-of-concept study to test the feasibility of using an all-in-one portable retinal camera for the screening of diabetic retinopathy in the Pacific Island of Vanuatu, which has a high rate of diabetes and its associated complications and a dearth of ophthalmologists. From February 10, 2020, through February 28, 2020, 49 patients with diabetes mellitus from three islands in Vanuatu were recruited to participate in the study. Demographics, basic health data and retinal photography were obtained. A non-mydriatic, handheld camera was used (Volk Pictor Plus). Eleven participants (24%) had referral-warranted diabetic retinopathy. There was moderately high inter-rater reliability for our dependent variables: referral status (κ = 0.62, 95% CI 0.42–0.83), retinopathy severity (κ = 0.76, 95% CI 0.55–0.96), and clinically significant macular edema (κ = 0.50, 95% CI 0.25–0.74). Our study confirms that portable handheld cameras can be used to obtain retinal images of sufficient quality for diabetic retinopathy screening even in resource limited environments like Vanuatu. Among this cohort, a relatively high (24%) prevalence of referral-warranted diabetic retinopathy was found in Vanuatu.
