Sohn EH, Strohbehn A, Stryjewski T, et al. - This study was undertaken to ascertain the preoperative characteristics, intraoperative and postoperative complications, and outcomes of eyes with posteriorly inserted vitreous base. Researchers performed a retrospective, observational, consecutive case series at 2 academic centers including a total of 37 patients who had posteriorly inserted vitreous base noted during vitrectomy. They examined 15 eyes in a histopathologic study of donor eyes to ascertain the average distance of the ora serrata from the vortex veins as this distance is uncertain. The results considered that 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. the findings suggested that redetachment and proliferative vitreoretinopathy still occur despite knowledge of the disorder and adjuvant treatments.
