Comparison of Observation Versus Vitrectomy for Patients With Hemorrhagic Posterior Vitreous Detachment
Background And Objective:
Patients with hemorrhagic posterior vitreous detachments (HPVDs) have a high rate of retinal tears and often develop retinal detachments (RDs). This study aims to compare outcomes of 25-gauge pars plana vitrectomy (PPV) for HPVD versus an observational group.
Patients And Methods:
Retrospective cohort study of 109 consecutive eyes of 105 patients diagnosed with HPVD; 66 eyes underwent PPV and 43 eyes were observed.
Results:
Twenty-four eyes (36.4%) in the surgical group were found to have tears intraoperatively not seen preoperatively. The median time to vitreous hemorrhage (VH) resolution was significantly shorter for the PPV group, 14 days (interquartile range [IQR]: 7 days to 35 days), compared to those who were observed, 58.5 days (IQR: 30 days to 91 days) (P < .0001). RDs occurred more frequently among observational patients (11.63%) compared to 1.52% of surgical patients (P = .0344).
Conclusion:
Twenty-five-gauge PPV for HPVD resulted in less RDs, diagnosis of occult retinal breaks intraoperatively, and shorter time to VH resolution. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:e288-e293.].
