Abstract
Age-related macular degeneration (AMD), a leading cause of blindness, has many risk factors with age being the most important one. Several treatment approaches have been developed, depending on the form of AMD. One of these approaches is the use of anti-VEGF agents in the treatment of the exudative form of AMD. This is a retrospective study with the aim of investigating and comparing the effect of three different anti–vascular endothelial growth factor (anti-VEGF) agents, bevacizumab, ranibizumab and aflibercept in the treatment of exudative age-related macular degeneration (AMD). The studied factors are: retinal nerve fiber layer thickness, central retinal thickness, total macular volume, visual acuity, and intraocular pressure. The study sample consisted of 120 AMD patients (80 females, 40 males), who were treated with anti-VEGF following either pro re nata or treat and extend regimens. The results showed that the visual acuity slightly improved in most of the subgroups, with some aflibercept subgroups showing significant improvement in the visual acuity. The intraocular pressure showed no significant change after the treatment with the three anti-VEGF agents. A significant decrease in the macular edema, which was evident by the significant reduction in both CRT and TMV, was noticed. Bevacizumab showed higher reduction in CRT followed by aflibercept then ranibizumab, while aflibercept showed the greatest reduction in the TMV followed by bevacizumab then ranibizumab. The RNFLT did not change significantly during the treatment except for one ranibizumab subgroup which showed a significant decrease in RNFLT after the 3rd injection.
