Exudative AMD, a frequent disease related to the population aging, is one of the leading causes of legal blindness and represents today a major public health problem. In the literature few long-term results (> 5 years) are available for this type of population. We aimed to present the results of a population of patients treated in real life for 5 years.
In this retrospective, monocentric registry, patients with exudative AMD treated in real life with intravitreal injections of anti-VEGF (Ranibizumab) were followed by PRN regimen with monthly control visits (CV). The primary objective was to study changes in visual acuity (VA) over time (initial VA, and VA at: 6, 12, 18, 24, 30, 36, 42, 48 months). The secondary objective was to assess whether the number of CV and Injection visits (IV) throughout follow-up were good predictor of VA evolution over time.
The studied population (109 patients and 131 eyes) had a usual female prevalence (64%) and a mean age of 78.4 ± 7.7 years.VA significantly increased during the first 6 months, with a delta ETDRS of 4.2 ± 15.2 letters (p = 0.0288). VA declined thereafter until the end of the follow-up, but without any statistical significance between the different controls (table 1).The mean number of CV and IV decreased all along the follow-up and this decrease was significant most of the time (table 2).
Anti-VEGFs IVTs represent a reliable treatment for exudative AMD, even in the long term (at 5 years). PRN regimen with regular follow-up and treatment is necessary to stabilize patients' AV over time. The follow-up should be adapted by the ophthalmologist to the progress of each patient, in order to avoid over or under treatment, which, in both cases, could deleterious to the final result.
