ABSTRACT
PURPOSE:
The study analyzes long-term (three years) clinical effectiveness of anti-VEGF treatment of neovascular age-related macular degeneration (nAMD) and attempts to identify the most clinically significant associations between the functional and structural parameters. MATERIAL ANDMETHODS:
The study included 122 patients (122 eyes) diagnosed with nAMD, mean age -73.4±6.6 years old. Prospective follow-up lasted 144 weeks. All patients were treated with angiogenesis inhibitor (aflibercept 2 mg), and most of them (72.9%) - according to the Treat-and-Extend protocol.RESULTS:
The average number of injections was 7.39±1.28, 4.63±0.97 and 4.06±0.81 during the first, second and third years of the follow-up, respectively. The mean baseline best-corrected visual acuity (BCVA) was 0.24±0.21. After three loading doses, BCVA increased to 0.33±0.26 (+0.09; 37.5%), by the end of follow-up BCVA was 0.35±0.27 (+0.11; 45.8%). Central retinal thickness (CRT) decreased from 314.89±88.07 µm to 234.4±42.8 µm (a 25.5% decrease) by the end of the follow-up. After three loading injections baseline functional and anatomical parameters had the most significant correlations (r≥0.7, p<0.05) with intraretinal fluid, ellipsoid zone integrity and the area of macular atrophy.CONCLUSIONS:
Analysis of the morphological and functional outcomes by the end of the first year demonstrates the feasibility of preserving the results while reducing the number of visits and injections according to the Treat-and-Extend protocol. Achieving maximum improvement of functional parameters most significantly correlated with changes in such biomarkers as central retinal thickness, area of macular atrophy and integrity of the ellipsoid zone.Palavras-chave
