摘要
BACKGROUNDANDOBJECTIVE: To assess surgical and visual outcomeswith pars plana vitrectomy (PPV) in closed-globe injuries resulting in anterior and posterior segment pathologies and evaluate the factors influencing the prognosis. PATIENTS AND METHODS: Retrospective ob servational study. Fortyseven eyes of 47 consecutive patients who underwent PPV because of closed-globe injury between January 1992 and August 2003 were reviewed. Surgical and visual outcomes and prognostic factors were analyzed according to the Ocular Trauma Classification System. RESULTS: Preoperative visual acuity was less than 4/200 in 49%of eyes, classified as grades IV to V After surgery, this ratio was 23%(P < .05)-. Final visual acuity was statistically significantly better in grade I (P=.0001), grade II (P=.002), and relative afferent pupillary defect-negative (P=.0001) injuries. Maculopathy was the most common adverse outcome influencing final visual acuity (32%), followed by secondary glaucoma (13%) and proliferative vitreoretinopathy (8%). CONCLUSION: PPV is a favorable treatment modality in severe closed-globe injuries. Assessment of injuries with respect to the Ocular Trauma Classification System seemed to predict visual outcomes in this series.
