Abstract

Purpose. To analyze clinical efficacy of anti-VEGF therapy for diabetic macular edema (DME) in eyes with vitreous loss. Material and methods. 34 patients (38 eyes) with vitreous loss and DME were examined: on the background of pre-proliferative diabetic retinopathy (PPDR) (18 eyes) and proliferative diabetic retinopathy (PDR) (20 eyes) (the main group). The comparison group consisted of 40 patients (40 eyes) with native vitreous body and DME on the background of PPDR (20 eyes) and PDR (20 eyes). Intravitreal injection of Lucentis 0.5 mg (IVIL) was carried out according to scheme «three monthly injections», then — to scheme «on demand». Results. Complete regression of DME in eyes with vitreous loss occurred in 74 % of cases; in eyes with native vitreous body — in 75 %. The duration of postoperative reaction in eyes with vitreous loss was up to 10–14 days, compared with 1–3 days in eyes with native vitreous body. The results of the study revealed, that number of IVIL was significantly less in patients with DME on the background of PPDR, than with PDR. Conclusions. The presence of local neuroepithelial detachment on the background of diffuse DME is prognostically favorable factor for anti-VEGF therapy. The effectiveness of IVIL in treatment of DME is comparable in eyes with native vitreous body and vitreous loss. Keywords: diabetes mellitus, diabetic macular edema, pre-proliferative diabetic retinopathy, proliferative diabetic retinopathy, vitreous loss, Lucentis intravitreal injection
