Analysis of optical coherence tomography angiography measurements following retinal detachment surgery

Muhammed Mustafa Kurt, Tugba Cetinkaya

Abstract

To analyze the optical coherence tomography angiography (OCTA) measurements in patients who underwent pars plana vitrectomy (PPV) due to rhegmatogenous retinal detachment (RRD). The study was conducted retrospectively in a single-centered eye clinic. Fifteen patients were enrolled in the study. The PPV group (or Study group) included 15 eyes performed PPV±phacoemulsification and the control eyes included 15 fellow eyes without any vitreoretinal surgical procedures. Postoperative 6-month OCTA measurements of the study and control eyes were compared for statistical analysis. The PPV group was also assessed in terms of Pseudophakic PPV and Phakic PPV subgroups. The average age of the patients was 57.72±6.32 years. Mean superficial retinal vessel density (VD, %) measurement of the superior hemifield in the PPV group showed a significantly lower result when compared to the control eyes (48.3±2.91 vs 50.11±2.59, p=0.031). Whereas no significant differences were noted in any segments of deep retinal VD measurements between the PPV and control eyes. We did not also observe any significant differences in any segments of both superficial and deep retinal VD measurements between the Pseudophakic PPV and Phakic PPV subgroups of the study group. Our study results concluded that PPV can lead to a partially decreased superficial retinal vessel density measurement in OCTA images, but phacoemulsification may not affect retinal vessel density measurements.

Key words: Pars plana vitrectomy, vessel density, optical coherence tomography angiography
