PURPOSE: To evaluate the surgical approach of pars plana vitrectomy combined with 360° retinotomy and silicon oil tamponade in the treatment of patients with large subretinal hemorrhage. METHODS: Prospective, nonrandomized, and noncomparative case series study. Consecutive patients with breakthrough vitreous hemorrhage and massive subretinal hemorrahge were recruited to have combined surgery of pars plana vitrectomy with 360° retinotomy and silicone oil temponade. The main outcomes were best-corrected visual acuity, retina status, and postoperative complications. RESULTS: Twenty-one patients (21 eyes) were included. The mean follow-up was 19.9 ± 7.4 months. The mean preoperative thickness of subretinal hemorrhage was 4.25 ± 0.69 mm. All the patients were observed to have choroidal neovascularization during the surgical procedure. The mean logarithm of the minimum angle of resolution best-corrected visual acuity (Snellen equivalent) significantly improved from preoperatively 2.64 (hand movement) to 1.73 (7/400), 1.50 (6/200), 1.51 (6/200), and 1.45 (7/200) at 1 month, 3 months, 6 months after the initial surgery, and final follow-up. Postoperative complications included temporary higher intraocular pressure, silicone oil emulsification, lens opacification, epimacular membrane, retinal pigment epithelium loss, and subretinal fibrosis. At the end of the follow-up, retinas were all reattached without any recurrence of choroidal neovascularization. CONCLUSION: Pars plana vitrectomy combined with retinotomy and silicone oil tamponade is effective for eyes with breakthrough vitreous hemorrhage and massive subretinal hemorrahge.
