To evaluate anatomical and functional outcomes of surgical displacement of macular hemorrhages complicating exsudative age-related macular degeneration (AMD) after vitrectomy, subretinal rtPA (recombinant tissue plasminogen activator) injection, intravitreal bevacizumab injection and gaz tamponade.Retrospective case series, including 26 patients with submacular hemorrhage, who underwent a surgical displacement within 15 days after the onset of symptoms. Optical coherence tomography (OCT) was carried out to measure the diameter of the hemorrhage and to specify the relation with retinal pigment epithelium. Anatomical success was defined as a total displacement of the hemorrhage away from the fovea at first postoperative visit. Visual acuity improvement was measured at 1 and 6 months and at final postoperative visit.The procedure resulted in hemorrhage displacement away from the fovea in 20 eyes (81%). Visual acuity significantly improved by 5,8 (±7,2) lines (P=0.0003) at 1 month postoperatively, 7,4 (±6,7) lines (P=0.0004) at 6 months and 7,4 (±7,4) lines (P=0.0002) at final postoperative visit (16,5±19,8 months). There was an inverse correlation between hemorrhage diameter and final acuity improvement (Pearson correlation coefficient P=-0.60 (IC 95% [-0.81; -0.26]; P=0.002)).Vitrectomy with subretinal rtPA injection was found to be effective for the displacement of AMD hemorrhage in 81 % of the patients. Mean final visual acuity improved by more than 7 lines. |
