Abstract

Introduction: The aim of this study was to evaluate the changes in macular structure and visual function of patients with diabetic macular edema (DME) after intravitreal aflibercept injection.

Methods: Twenty-five patients (43 eyes) diagnosed with DME were included in this study. All patients underwent aflibercept monthly for 3 months. The study's endpoints included the best corrected visual acuity (BCVA), central retinal thickness (CRT), fovea avascular zone (FAZ) area, vessel density of superficial retinal capillary plexus (SVD), vessel density of deep retinal capillary plexus (DVD), mean light sensitivity (MLS), 2° fixation rate (P1) and 4° fixation rate (P2).

Results: Before treatment and after the third treatment, the LogMAR BCVA was 0.69 ± 0.27 and 0.40 ± 0.18, the CRT was 471.10 ± 159.93 μm and 319.84 ± 113.51 μm, the MLS was 18.14 ± 3.97 dB and 21.68 ± 3.55 dB, P1 was 69 (47, 87)% and 88 (72, 92)%, and P2 was 90 (83, 97)% and 97 (93, 99)%, respectively. After treatment, CRT decreased, BVCA, MLS, and fixation stability improved (all p < 0.001). Post-treatment, FAZ area, SVD, and DVD showed no significant changes (all P > 0.05). MLS was negatively correlated with LogMAR BCVA and CRT, and positively correlated with P1 and P2.

Conclusion: In short term, aflibercept was effective in reducing CRT and improving BCVA, MLS, and fixation stability in DME patients.

玻璃体内注射阿布西贝治疗糖尿病性黄斑水肿:结构和功能改善。
前言:本研究旨在评价糖尿病性黄斑水肿(DME)患者玻璃体内注射阿布西贝后黄斑结构和视觉功能的变化。方法:选取确诊为DME的患者25例(43只眼)进行研究。所有患者连续3个月每月接受阿伯西普治疗。研究终点包括最佳矫正视力(BCVA)、视网膜中央厚度(CRT)、中央凹无血管区(FAZ)面积、视网膜浅毛细血管丛血管密度(SVD)、视网膜深毛细血管丛血管密度(DVD)、平均光敏度(MLS)、2°固定率(P1)和4°固定率(P2)。结果:治疗之前和之后第三治疗的LogMAR BCVA 0.69 ±  0.27和0.40±0.18 ,CRT为471.10 ±159.93   μm和319.84±113.51  μm,美国为18.14 ±3.97   dB和21.68±3.55  dB, P1是69(87)%和88(72、92)%,和P2是90(83、97)%和97(93、99)%,分别。治疗后CRT降低,BVCA、MLS、固定稳定性提高(p均 p > 0.05)。MLS与LogMAR BCVA、CRT呈负相关,与P1、P2呈正相关。结论:阿非利西普短期内可有效降低DME患者的CRT,改善BCVA、MLS和固定稳定性。

期刊介绍: Frontiers in Medicine publishes rigorously peer-reviewed research linking basic research to clinical practice and patient care, as well as translating scientific advances into new therapies and diagnostic tools. Led by an outstanding Editorial Board of international experts, this multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, clinicians and the public worldwide. In addition to papers that provide a link between basic research and clinical practice, a particular emphasis is given to studies that are directly relevant to patient care. In this spirit, the journal publishes the latest research results and medical knowledge that facilitate the translation of scientific advances into new therapies or diagnostic tools. The full listing of the Specialty Sections represented by Frontiers in Medicine is as listed below. As well as the established medical disciplines, Frontiers in Medicine is launching new sections that together will facilitate - the use of patient-reported outcomes under real world conditions - the exploitation of big data and the use of novel information and communication tools in the assessment of new medicines - the scientific bases for guidelines and decisions from regulatory authorities - access to medicinal products and medical devices worldwide - addressing the grand health challenges around the world
