Rhegmatogenous retinal detachment (RRD) is caused by the movement of liquefied vitreous gel into the subretinal space through a retinal break. RRD is commonly treated with scleral buckling (SB) or pars plana vitrectomy (PPV). Blood flow at the macula, in contrast to the other areas of the retinal vascular system, does not change following scleral buckling. This study aims to explore the macular perfusion changes in the RRD-treated eyes and to evaluate the influence of these changes on the final visual outcomeusing Optical Coherence Tomography Angiography (OCTA).
AIM OF THE WORK
The aim of this work was to assess the macular perfusion changes in patients with Macular-off RRD after successful buckling surgery using OCTA.
PATIENT AND METHODS
It's an observational case-control study. The study involved 60 eyes from 30 participants. The study group included 30 eyes with a history of successful scleral buckling surgery for macula-off rhegmatogenous retinal detachment (RRD) that were repairedat the Main University Hospital (Alexandria University) by cryotherapy of the retinal breaks with the application of a circumferential buckle (band 240 with segmental tire 276). The control group included 30 eyes (contralateral eyes of the study group). 18 of the included patients were men (60%) and 12 were women (40%). Patients that were included in the study had ages spanning from 15 to 80, with a mean age of 46.37+16.45 years.
