Background and objective: This study evaluated the residual subfoveal fluid (SFF) immediately after rhegmatogenous retinal detachment (RRD) repair using intraoperative optical coherence tomography (iOCT).
Patients and methods: This retrospective cohort study assessed fovea-involving RRD repaired by pars plana vitrectomy (PPV) using different drainage techniques. iOCT images were acquired through the fovea at the start of the case prior to initiating vitrectomy and then again immediately prior to introduction of tamponade.
Results: Ten eyes (32.3%) received perfluoro-n-octane (PFO), 12 (38.7%) underwent a posterior drainage retinotomy, and nine (29.0%) had drainage through the retinal break. There was no significant difference in the mean SFF thickness between eyes in either group (P = .85). There was no significant association between SFF thickness on iOCT and functional or anatomic outcomes (P > .05).
Conclusion: There is no difference in the amount of residual SFF as measured on iOCT during RRD repair with pars plana vitrectomy using either direct drainage, drainage retinotomy, or PFO. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:497-503.].
