SCIENTIFIC POSTER 2016_Residual Vitreous Cortex at the Fovea During Vitrectomy for Primary Rhegmatogenous RD Repair Eun Hyung Cho


We investigated the effectiveness of the removal of the residual vitreous cortex in the fovea during vitrectomy for primary rhegmatogenous retinal detachment repair.


We retrospectively reviewed the chart and the operation video of the 50 patients (50 eyes) who underwent vitrectomy for retinal detachment repair and observed more than 6 months. After triamcinolone acetonide injection, we observed vitreous remnant on the surface of the retina. Residual vitreous cortex was removed with scrapper. After surgery, we observed whether epiretinal membrane occurred for at least 6 months. We graded epiretinal membrane according to the visual acuity.


Of total 50 eyes, 34 eyes (68%) showed macular residual vitreous cortex and we removed them with a diamond dusted scrapper. After vitrectomy, macular pucker occurred in 11 eyes (22%) (9 eyes with thin membrane (18%), 2 eyes with thick membrane (4%)). In eyes (n=16) without residual vitreous cortex during vitrectomy, thin membrane occurred in one eye (6.25%) and thick membrane did not found. In eyes that had residual vitreous cortex and were removed during vitrectomy (n=34), thin membrane occurred in 8 eyes (23.5%) and thick membrane occurred in 2 eyes (5.8%) (1 eye had foveal membrane and the other eye had extrafoveal membrane). In the one eye that had thick extrafoveal pucker, triamcinolone dust was partly scattered in the macula so pucker occurred in area without removing vitreous cortex.


During RD vitrectomy, postoperative macular pucker rate was low in eyes without residual vitreous cortex. Removal of vitreous cortex in eyes with them reduced rate of clinically significant macular pucker after vitrectomy for primary rhegmatogenous retinal detachment repair and reoperation.
