Subretinal coapplication of recombinant tissue plasminogen activator and bevacizumab for neovascular age-related macular degeneration with submacular haemorrhage.

AIM

To evaluate the efficacy and safety of pars plana vitrectomy (ppV) with subretinal coapplication of recombinant tissue plasminogen activator (rtPA) and bevacizumab, and fluid-gas exchange for neovascular age-related macular degeneration (AMD) with submacular haemorrhage (SMH).

METHODS

Consecutive interventional case series of 12 patients with neovascular AMD with SMH with a maximum history of 14 days. All patients underwent ppV with subretinal coapplication of rtPA and bevacizumab, and fluid-gas (20% SF6) exchange. Phakic patients underwent concomitant cataract surgery. Additional injections of bevacizumab were applied intravitreally 4 and 8 weeks postop.

RESULTS

Complete displacement of SMH from the fovea was achieved in 9 of 12 patients. The mean best-corrected visual acuity (BCVA) improved significantly from preop logMAR 1.9 (range 3.0 to 0.7) to logMAR 1.2 (range 3.0 to 0.3) at 4 weeks postop (p = 0.01) and to logMAR 0.9 (range 1.6 to 0.2) at 12 weeks postop (p = 0.006). The mean improvement of BCVA 4 weeks postop as compared with preop was logMAR 0.7 (range -0.2 to 2.3). The mean improvement of BCVA 12 weeks postop as compared with preop was logMAR 0.96 (range -0.3 to 2.8). Overall, at 12 weeks postop, BCVA had improved in 10 patients, remained unchanged in one patient and worsened in one patient.

CONCLUSION

PpV with subretinal coapplication of rtPA and bevacizumab, and fluid-gas exchange effectively displaces SMH and improves visual acuity in most patients.
