Abstract

Summary


Objective: To evaluate functional and anatomical results of intravitreal ranibizumab injection cours of wet age-related macular degeneration treatment over a 12-month observation period. Subject and method: 23 eyes in 22 patients with wet age-related macular degeneration treatment was performed according to the following schedules: 3 intravitreal injections of 0.5mg ranibizumab at monthly intevals (saturation phase). Further injection was based on the activity of neovascular process. Result: Mean pre-treatment best corrected visual acuity was 0.09. After the third ranibizumab injection the best results, 0.22 were seen, 12-month results were 0.21. Baseline mean central retinal thickness was 435µ.  After the third injection was 358µ. After 12 months it was 358µ. The mean number of injections in the 12-month period was 3.7. Conclusion: Treatment intravitreal ranibizumab injection according to presented scheme provides wet age-related macular degeneration patients with a chance of stabilization and improvement of topical state, with a lower number injection and preserved topical and general  safety. Regular monthly control in necessary to be able react rapidly to smallest signal deterioration, not only in visual acuity, but also OCT images.
