摘要

AIM: To describe the long-term observation of vitrectomy without subretinal hemorrhage(SRH) management for massive vitreous hemorrhage(VH) secondary to polypoidal choroidal vasculopathy(PCV). METHODS: This is a retrospective, consecutive case series. A total of 86 eyes of 86 patients with >14d of massive VH associated with PCV were included. All patients underwent vitrectomy without SRH management, followed by intravitreal ranibizumab injections and/or photodynamic therapy(PDT) as needed. The main outcome measures were best-corrected visual acuity(BCVA), postoperative adverse events and the recurrence of VH. RESULTS: The average follow-up period was 25.5±9.2 mo(range 12-35 mo). Mean BCVA at baseline(2.16±0.39 logM AR)had improved significantly, both 3 mo after surgery(1.42±0.66 log MAR, P<0.001) and by the last visit(1.23±0.74 logM AR, P<0.001). The common postoperative complications included macular subretinal fibrosis in 14 eyes(16.3%) and ciliary body detachment in 4 eyes(4.7%).Nineteen eyes(22.1%) received following treatment with ranibizumab injections without/with PDT, and 15(17.4%)were resolved. Four eyes(4.7%) had recurrent hemorrhage during the follow-up period. In multiple regression analysis,thicker SRH(beta=0.33, P=0.025) in the preoperative B-scan and the presence of foveal subretinal fibrosis(beta=0.28, P=0.018) in the follow up were associated with poor postoperative BCVA. CONCLUSION: Vitrectomy without SRH management for massive VH secondary to PCV improved/stabilized visual function in the long-term observation. Eyes presenting with thicker SRH preoperatively and forming foveal subretinal fibrosis in the follow-up period tended to have worse BCVA.
