摘要

目的:本研究旨在评估基于扫源光学相干断层成像(SS-OCT)的生物测量、眼底照片及其组合与金标准光谱域光学相干断层成像(SD-OCT)在检测中心内糖尿病性黄斑水肿(CI-DME)方面的一致性:我们进行了一项回顾性横断面研究,共有55名受试者(78只眼)通过临床和SD-OCT(卡尔蔡司医疗技术股份公司)诊断出患有糖尿病性黄斑水肿(DME)。研究采用了眼球后45度彩色眼底照片(Crystal-Vue NFC-700)、基于SS-OCT的生物测量(IOL-Master 700)获得的1毫米黄斑扫描以及SD-OCT获得的黄斑立方体扫描来检测DME,并将其分为CI-DME和NCI-DME:我们的研究结果表明,与金标准(SD-OCT)相比,基于 SS-OCT 的生物测量在检测 CI-DME 方面的灵敏度为 1(0.94-1.00),特异度为 0.63(0.31-0.89)。当结合眼底照片数据时,特异性降至 0.32(0.15-0.53)。单独使用眼底照片检测 CI-DME 的灵敏度较低,为 0.52(0.38-0.64),特异度为 0.45(0.16-0.76):总之,基于SS-OCT的生物测量法可作为一种有效的工具,用于检测接受白内障手术的糖尿病患者的CI-DME,并可在没有SD-OCT设备的中心作为一种筛查工具。

Diagnostic Utility of Swept-Source OCT-Based Biometry and Fundus Photographs Compared to Spectral Domain OCT in Center-Involving Diabetic Macular Edema.

Purpose: This study was aimed to evaluate the agreement between the swept-source optical coherence tomography (SS-OCT)-based biometry, fundus photographs, and their combination, in comparison to the gold standard spectral-domain optical coherence tomography (SD-OCT) for the detection of center-involving diabetic macular edema (CI-DME).

Methods: We conducted a retrospective cross-sectional study involving 55 subjects (78 eyes) diagnosed with diabetic macular edema (DME) detected clinically and on SD-OCT (Carl Zeiss Meditec AG). Post-mydriatic 45-degree color fundus photograph (Crystal-Vue NFC-700), 1 mm macular scan obtained from SS-OCT-based biometry (IOL-Master 700), and macula cube scan obtained from SD-OCT was used to detect and grade DME into CI-DME and NCI-DME.

Results: Our findings revealed that SS-OCT-based biometry was noted to have a high sensitivity of 1 (0.94-1.00) and a specificity of 0.63 (0.31-0.89) in detecting CI-DME compared to the gold standard (SD-OCT). When combined with data from fundus photographs, specificity decreased to 0.32 (0.15-0.53). Fundus photographs alone exhibited a low sensitivity of 0.52 (0.38-0.64) and a specificity of 0.45 (0.16-0.76) in CI-DME detection.

Conclusion: In conclusion, SS-OCT-based biometry can be used as an effective tool for the detection of CI-DME in diabetic patients undergoing cataract surgery and can serve as a screening tool in centers without SD-OCT facilities.

期刊介绍: Ophthalmic Epidemiology is dedicated to the publication of original research into eye and vision health in the fields of epidemiology, public health and the prevention of blindness. Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications and letters to the editor on all subjects related to ophthalmic epidemiology. A broad range of topics is suitable, such as: evaluating the risk of ocular diseases, general and specific study designs, screening program implementation and evaluation, eye health care access, delivery and outcomes, therapeutic efficacy or effectiveness, disease prognosis and quality of life, cost-benefit analysis, biostatistical theory and risk factor analysis. We are looking to expand our engagement with reports of international interest, including those regarding problems affecting developing countries, although reports from all over the world potentially are suitable. Clinical case reports, small case series (not enough for a cohort analysis) articles and animal research reports are not appropriate for this journal.
