[Final visual acuity in patients undergoing posterior vitrectomy for Terson's syndrome: a series of 11 cases].

PURPOSE: The purpose of this study was to assess visual acuity after vitrectomy for Terson's syndrome. METHODS: This is a retrospective study of 11 eyes (7 patients), who underwent pars plana vitrectomy between 1996 and 1998. Visual acuity was evaluated at 1, 5 and 12 months. We also report immediate and delayed complications. RESULTS: Initial visual acuity was below 20/200 for 9 patients (81%). Final visual acuity was 20/25. An epiretinal membrane was noticed in two patients during the surgical procedure. Final visual acuity for those two patients was only 20/40 and 20/100. Two patients developed cataract following vitrectomy, one developed an endophthalmitis with good vision recovery. CONCLUSION: Vitrectomy for vitreous hemorrhage in Terson's syndrome after three months follow up is a solution without major risks and has a good visual prognosis. Final visual acuity of patients after vitrectomy for Terson's syndrome is good. However, Terson's complications such as epiretinal membrane and cataract are limiting factors for good visual recovery.
