    Abstract:
    BACKGROUND: The aim of this study was to evaluate the role of vitrectomy in patients with visually disturbing vitreous opacities. PATIENTS AND METHODS: A retrospective analysis of the patient characteristics and the outcome of all pseudophacic eyes, which consecutively received in the decade 1996 to 2005 20 G pars plana vitrectomy for visually disturbing floaters, was carried out at the Mainz University Eye Clinic. RESULTS: Forty-one eyes of 32 patients (63 % university graduates, median age: 64 years) were included in the study. The mean axial length of the globe was 25.3 mm (range: 22.8 to 28.9 mm). Additional pathologies having influence on the vitreous condition were history of laser or cryo retinopexy (12 ×), buckle surgery (5 ×), complicated cataract surgery (16 ×) and Nd:YAG laser capsulotomy (4 ×). Vitreous floaters were considered to be the result of posterior vitreous detachment alone in 61 %, of asteroid hyalosis accompanied by posterior vitreous detachment in 17 %, and vitreous syneresis in 15 % of the eyes. Intraoperatively retinopexy with endolaser or cryo was performed in 6 % of cases. A secondary retinal detachment occurred in one eye (2 %). Thirty-one of 32 patients reported to be very satisfied with the postoperative result. Objectively, their visual acuity was better than or equal to preoperative acuity in 95 % of the eyes. CONCLUSION: Pars plana vitrectomy provides a highly effective treatment for visually disturbing vitreous floaters. In an era in which the expectations and demands of individuals on the quality of vision and life have increased significantly, with careful case selection the benefits of the surgical intervention may outweigh the surgical risks.
