Comparative Study Of Visual Outcomes Following Corrective Vitrectomy: Non-Traumatic Versus Traumatic Etiologies

Introduction: Nucleus drop is a rare and serious complication. We investigated visual outcomes following corrective surgery, and compared outcomes between surgeries that followed traumatic injuries and those where the etiology was nontraumatic. Method: A retrospective cohort study was performed using information collected from medical records regarding cases of vitrectomy performed for nucleus drop. Patients were grouped into traumatic and non-traumatic cases. After pars plana vitrectomy and nucleus removal with use of a phacofragmatome, all data were collected according to a standard follow-up format. Results: Our cohort consisted of 37 eyes of 37 patients. Mean patient age was 58.8+/-9.35, ranging from 31 to 75 years (Table1). Of these cases, 12 (32.4%) were traumatic and 25 (67.6%) followed cataract surgeries. We found that vision in 15 (40.4%) cases improved to more than 6/24 and in 5 (13.5%) it did not improve (>1/60). Conclusion: Visual outcome following corrective vitrectomy for nucleus drop may be satisfactory if managed well; no significant difference in outcome was noted based on etiology.
