Dealings between cataract and retinal reattachment surgery in PVR

Introduction. to evaluate the impact of the eye lens status and oil side effects on the outcome of vitreoretinal surgery in retinal detachment with proliferative vitreoretinopathy (pvr) and a temporary silicone oil tamponade (sot). methods. 101 eyes were analyzed retrospectively and 103 eyes prospectively in regard to their retinal reattachment success rate and key factors for the outcome. subgroup analysis of 27 eyes with scheimpflug lens photography (slp) before and after retinal reattachment service with sot was performed. for slp (65% phakic eyes) a pentacam densitometry reference body with 3 mm diameter was chosen and 3 segments (anterior/mid/posterior) were evaluated separately after a quality check. results. the retinal reattachment rate was highest in the prospective pseudophakic group (p = 0.039). lens transparency loss occurred earlier in middle aged patients than in younger patients. besides the nucleus,layers posterior and anterior to it showed specific transparency changes. the emulsification rate was higher when eyes had been operated on in the anterior chamber before retinal reattachment service. conclusions. retinal reattachment surgery seems to benefit from preoperative cataract removal. we found significant lens changes in the nucleus as well as in the layers anterior and posterior to it. this corresponds to the histology of the lens epithelium published before. © 2016 svenja deuchler et al.
