Intravitreal treatment in patients with exudative age-related macular degeneration and visual acuity∈≤∈0.05 Retina

Abstract

Background: To investigate intravitreal treatment efficiencies in patients suffering from exudative ARMD with a BCVA∈≤0.05. Methods: Retrospective analysis: Analysis parameters were lesion type, BCVA at baseline and at follow-up, the intravitreal drug used, and its application frequency. Patients were divided into: 1) following injections of bevacizumab, triamcinolone, their combination, or ranibizumab regardless of their lesion subtype, 2) or by lesion subtype. Statistical tests were performed using Wilcoxon signed-rank tests, Kruskal-Wallis tests and multivariable logistic regressions. Results: Seventy four eyes of 74 patients were analyzed. Follow-up was at 12.0 to 15.7 weeks. Median difference of BCVA (logMAR) between baseline and follow-up was 0.000 (-0.030, 0.175) in classic (p∈=∈0.105), 0.000 (-1.15, 0.20) in occult (p∈=∈0.005), -0.200 (-1.20, 0.60) in cases with subretinal fluid (p∈=∈0.207), 0.000 (-0.60, 0.30) in pigment epithelial detachment (p∈=∈0.813), and 0.050 (-0.40, 0.70) in Junius Kuhnt maculopathy (p∈=∈0.344). BCVA increased∈≥∈0.2 logMAR in 4 (24 %) classic, 9 (47 %) occult, 6 (33 %) pigment epithelial detachment, 6 (55 %) subretinal fluid, in 29 (39 %) eyes regardless of the lesion type, and reached a BCVA∈≥∈0.05 in 7 (9 %) of those with a baseline BCVA 0.05. Conclusions: Results indicate that in patients with ARMD and a BCVA lower 0.05, intravitreal treatment may improve visual acuity, most probably in cases with occult lesions.
