Study Overview
Brief Summary
Age-related macular degeneration (AMD) is a leading cause of blindness in people over 50 years old. Neovascular AMD, the most severe form and the most severe is characterized by the appearance, spread and growth of subretinal neovessels. One of the major molecular mediators is the endothelial growth factor vascular (VEGF).
Intra-vitreous (IVI) injection of an anti-VEGF may slow the progression of Neovascular AMD and stabilize vision in the majority of cases. Ranibizumab (Lucentis®) is one of the anti-VEGF molecules approved in Belgium to treat neovascular AMD.
At the start of its use, ranibizumab was first injected monthly and then according to the "reactive" protocol. Over time, a new strategy of treatment was born: the "treat-and-extend" (T&E). This is 'made to measure' protocol for each patient aiming to reduce the frequency of injections while guaranteeing inactivity of the disease. It starts with the loading dose, i.e. 3 injections given 4 weeks apart. Subsequently, the interval is lengthened by slices of 1 or 2 weeks provided that the visual and anatomical results remain stable. In the event of deterioration, the interval is shortened while keeping a minimum of 4 weeks between each IIV.
The efficacy and safety of ranibizumab, when used in a proactive regimen of T&E, has been shown in the CANTREAT randomized controlled trial. However, there is a lack of more data on T&E used in current practice, and particularly on the number of injections and treatment intervals over a minimum treatment period of 24 months.
The aim of this retrospective study carried out at the CHU Brugmann Hospital is to determine the number of injections and the intervals necessary to have encouraging results in visual acuity over a treatment period of at least two years.
