Purpose: To evaluate the utility of intraoperative optical coherence tomography (iOCT) during pars plana vitrectomy surgery (PPV) for dense vitreous hemorrhage (VH).
Methods: The authors retrospectively reviewed medical records of 30 eyes from 30 patients in which iOCT was evaluated during PPV for dense VH that precluded preoperative OCT assessment. iOCT images were qualitatively evaluated for retinal abnormalities that might impact intraoperative or perioperative management.
Results: There were 18 males (60%) and 12 females (40%). The mean age of patients in the study was 56.0 ± 14.5 years (range: 34-86 years). The etiology for VH was proliferative diabetic retinopathy (18 eyes, 60.0%), retinal vein occlusion with neovascularization (5 eyes, 16.7%), age-related macular degeneration (2 eyes, 6.7%), retinal tear (2 eyes, 6.7%), posterior vitreous detachment (1 eye, 3.3%), retinal arterial macroaneurysm (1 eye, 3.3%) and Eale’s disease (1 eye, 3.3%). iOCT revealed epiretinal membrane (7 eyes, 23.3%), tractional retinal detachment (6 eyes, 20.0%), rhegmatogenous retinal detachment (2 eyes, 6.7%) and macular edema (1 eye, 3.3%). The median number of scan sessions per case was 2.87 ± 1.61 (range: 1-8 sessions) with 4.70 ± 2.20 (range: 3-11 sessions) median total scans. The mean time at which surgery was paused to perform iOCT imaging was 3.18 ± 1.53 minutes (range: 1.70-7.17 minutes).
Conclusions: iOCT during PPV for dense VH may provide surgeons with clinically relevant information that may influence perioperative management.
