Verteporfin photodynamic therapy combined with intravitreal ranibizumab in neovascular age-related macular degeneration: 24-month follow-up

Purpose: to evaluate the efficacy and safety of combined therapy with Photodynamic Therapy with Verteporfin (PDT-V) and intravitreal ranibizumab same-day compared with monotherapy with ranibizumab (three monthly injections ) for the treatment of the choroidal neovascularization (CNV) due to age-related macular degeneration (AMD). Type of study : open-label, randomized controlled trial (RCT). Materials and Methods: 17 eyes of 17 patients were consecutively enrolled and randomly assigned to ranibizumab intravitreal injection + PDT compared with a control group of 30 eyes of 30 patients treated with only ranibizumab 0.5mg in three monthly injections. Best corrected visual acuity (BCVA), central macular thickness (CMT) on optical coherence tomography were examined before and after treatment. Patients were followed-up for twelve months. Results: in the combined therapy group, the mean baseline BCVA is 32.6 letters, at 24-months after treatment it’s 31.4 letters with a loss of 1.2 l

Results: in the combined therapy group, the mean baseline BCVA is 32.6 letters, at 24-months after treatment it’s 31.4 letters with a loss of 1.2 letters. The mean central thickness at baseline is 314.6 µm. After twenty four months the mean CMT is 222.5 µm, with mean CMT reduction of 92.1µm. In the ranibizumab-alone group, the mean baseline BCVA is 29.1 letters at 24-months it’s 28.6 letters with a little loss of 0.5 letters. The mean baseline CMT is 297.6 µm, at 24-months it is 235.9 µm, with mean CMT reduction of 61,7µm. Conclusions: the two treatments showed the same efficacy from a functional and anatomic point of view with a less number of retreatments in the combined therapy group. There were no serious ocular adverse events such as retinal detachment, endophthalmitis or ocular hypertone.
