Abstract
Purpose:
To evaluate the outcomes and prognostic factors of pars plana vitrectomy (PPV) combined with subretinal injection of recombinant tissue plasminogen activator (rt-PA) for submacular hemorrhage (SMH) patients with or without vitreous hemorrhage.
Methods:
Sixty-four eyes of 64 patients with SMH patients underwent PPV with subretinal injection of rt-PA. Best-corrected visual acuity (BCVA), SMH displacement, and postoperative complications were analyzed. Predictive factors of the final BCVA were determined using multivariant linear regression.
Results:
There were 26 eyes with VH and 38 without VH BCVA significantly improved in both VH group (from 2.27±0.40 to 1.25±0.70 LogMAR) and non-VH group (from 1.76±0.55 to 0.85±0.65 LogMAR). Completely displacement of SMHs was observed in 47 (73.43%) eyes. Postoperative complications included recurrent SMH (4.69%), recurrent vitreous hemorrhage (10.94%), rhegmatogenous retinal detachment (3.13%), and epiretinal membrane (4.68%). Treatment-naive condition, early surgery, and younger age were significantly associated with better final BCVA (B =0.502, 0.303, and 0.021, respectively, with all p <0.05).
Conclusion:
PPV combined with subretinal rt-PA injection is an effective treatment for SMH patients with and without VH.
