Exudative age-related macular degeneration (AMD) – clinical knowledge treatment optimisation
Main Article Content
Abstract
Age-related Macular Degeneration (AMD) is the leading cause of blindness in developed countries. Vascular endothelial growth factor (VEGF) has emerged as a key factor playing role in patomechanism of wet AMD. Between 2004 and 2006, 3 anti-VEGF drugs were introduced to ophthalmology (pegaptanib, bewacyzumab i ranibizumab). Soon after in 2012 a new molecule – alfibercept was registered. Those VEGF inhibitors played a major role in wet AMD treatment. Over 71% of patients benefit from treatment while only 5% of cases faces visual impairment. From 55% to 71% of eyes have persistent retinal fluid despite injections. A small proportion of eyes that respond to initial therapy subsequently develop tachyphylaxis. In those cases modifying the protocol, switching drugs can individualize treatment to gain maximum anatomic and functional effect with minimum interventions.
