SCIENTIFIC POSTER 2016_Early PPV versus Delayed PPV for Spontaneous Fundus Obscuring Vitreous Hemorrhage Joo Yeon Kim


To compare the visual outcomes of early versus delayed intervention in the setting of fundus-obscuring vitreous hemorrhage (VH) presumed to be due to posterior vitreous detachment.


All eyes that presented with a fundus-obscuring VH defined as vision of 20/400 or worse, and requiring a B-scan at presentation from 2012 – 2014, were evaluated. Patients were divided into two groups: “Early Intervention” (vitrectomy performed within 1 week of diagnosis) and “Delayed Intervention” (vitrectomy performed after 1 week of diagnosis). Postoperative diagnoses on operation records were evaluated, and eyes that were diagnosed with VH due to diabetic retinopathy, vascular obstruction, and macular degeneration were excluded. Patients with previous history of retinopathy and recent trauma were also excluded. The main outcome measure studied were best-correct visual acuity (BCVA) at 2 months and 4 months after the surgery.


75 eyes met inclusion criteria with a mean follow-up of 120 days. 49 patients were in the “Early Intervention” group and 26 patients were included in the “Delayed intervention” group. The mean BCVA at onset, at 2 months and at 3 months in the “Early Intervention” group was logMAR 2.550, 0.601, 0.426 respectively. The mean BCVA at onset, at 2 months and at 3 months in the “Late Intervention” group was logMAR 2.740, 0.626, 0.486 respectively. The two groups showed no significant difference in the extent of improvement of vision (p<0.05). No patients showed progression to a macula-off retinal detachment in both groups.


Early surgical intervention results showed similar visual outcomes compared to a delayed surgical intervention. Other factors that may influence clinical outcomes of VH should be further investigated.
