Abstract

Objectives: To evaluate the changes in macular vessel density after treatment with vascular endothelial growth factor (VEGF) inhibitorsin center-involving diabetic macular edema (DME) and to compare these changes between anatomical responders and non-responders. Materials and Methods: This retrospective study included 22 eyes with center-involving DME. All eyes had 3 consecutiveadministrations of VEGF inhibitors. Optical coherence tomography (OCT) and OCT angiography (OCTA) of the macula with manualadjustment of segmentation lines were performed at baseline and after treatment. Vessel density in the central and parafoveal regions of the superficial and deep capillary plexus (SCP/DCP) were measured at baseline and after treatment. Vessel density and changes therein were comparedbetween anatomical responders and non-responders as defined by changes in central subfield thickness (CST). Results: Overall, there were no significant differences in vessel density in the central and parafoveal regions of the SCP and DCP after treatment comparedto baseline. After categorization by anatomical response, 12 eyes were responders (CST decreased by 173.7±47.7 µm) and 10 eyes were non-responders(CST increased by 20.8±38.9 µm) (p

Özet

Amaç: Merkez bölgeyi içeren diyabetik maküla ödeminde (DMÖ) vasküler endotelyal büyüme faktörü (VEGF) inhibitörleri ile tedavi sonrası maküler damar yoğunluğundaki değişiklikleri değerlendirmek ve bu değişiklikleri anatomik yanıt verenler ile vermeyenler arasında karşılaştırmak.Gereç ve Yöntem: Bu retrospektif çalışmaya merkezi tutulumu olan DMÖ’lü 22 göz dahil edildi. Tüm gözlere ardışık 3 VEGF inhibitörü uygulaması yapıldı. Tedaviden önce ve sonra segmentasyon çizgileri manuel olarak belirlenerek makülanın optik koherens tomografi (OKT) ve OKT anjiyografi (OKTA) görüntülemeleri yapıldı. Yüzeyel ve derin kapiller pleksusun (YKP/DKP) merkezi ve parafoveal bölgelerdeki damar yoğunluğu tedaviden önce ve sonra ölçüldü. Damar yoğunluğu ve değişiklikleri, merkezi alt alan kalınlığındaki (MAK) değişikliklere göre belirlenen anatomik yanıt verenler ve yanıt vermeyenler arasında karşılaştırıldı.Bulgular: Genel olarak, tedavi öncesi ve sonrası arasında merkezi ve parafoveal bölgelerde YKP ve DKP damar yoğunluğunda anlamlı bir fark yoktu. Anatomik yanıta göre yapılan sınıflandırmada 12 gözün yanıt verdiği (MAK 173,7±47,7 µm azaldı) ve 10 gözün yanıt vermediği (MAK 20,8±38,9 µm arttı) belirlendi (p
