■概念验证研究,以测试在瓦努阿图太平洋岛使用一体化便携式视网膜相机筛查糖尿病视网膜病变的可行性,糖尿病及其相关并发症的发病率很高,眼科医生匮乏。
■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了这项研究。人口统计,获得基本健康数据和视网膜摄影。非散瞳患者,使用手持相机(VolkPictorPlus)。
■11名参与者(24%)有转诊证明的糖尿病视网膜病变。我们的因变量有中等高的评分者间可靠性:转诊状态(κ=0.62,95%CI0.42-0.83),视网膜病变严重程度(κ=0.76,95%CI0.55-0.96),和临床显着黄斑水肿(κ=0.50,95%CI0.25-0.74)。
■我们的研究证实,即使在瓦努阿图等资源有限的环境中,便携式手持相机也可用于获得足够质量的视网膜图像,以进行糖尿病视网膜病变筛查。在这个群体中,在瓦努阿图发现有转诊许可的糖尿病性视网膜病变的患病率相对较高(24%).
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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).
UNASSIGNED: 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.
