Abstract

To determine the preoperative characteristics, intraoperative and postoperative complications, and outcomes of eyes with posteriorly inserted vitreous base. In this retrospective, observational, consecutive case series at 2 academic centers, 37 patients were studied who had posteriorly inserted vitreous base noted during vitrectomy. Posteriorly inserted vitreous base was defined as the insertion of the posterior hyaloid membrane being located posterior to the vortex veins. Fifteen eyes were analyzed in a histopathologic study of donor eyes to determine the average distance of the ora serrata from the vortex veins as this distance is uncertain. Posteriorly inserted vitreous base was identified during vitrectomy in 31 eyes with rhegmatogenous retinal detachment (84%), 4 with macular hole (11%), 1 with vitreous hemorrhage, and 1 with epiretinal membrane. Adjunctive buckle was used in 24%; 54% had 360° laser. Average number of tears seen preoperatively in those with rhegmatogenous retinal detachment was 3.1. Thirty percent had new breaks identified intraoperatively. Forty-one percent had lattice degeneration; new breaks were found in 40% of eyes with lattice. Thirteen percent of rhegmatogenous retinal detachments developed proliferative vitreoretinopathy. Average distance from the ora serrata to the vortex veins was 7.6 mm. Any eye undergoing vitrectomy may have posteriorly inserted vitreous base, but those with a high number of retinal breaks and lattice near the equator may be at highest risk. Redetachment and proliferative vitreoretinopathy still occur despite knowledge of the disorder and adjuvant treatments.
