abstract = "Purpose: To analyse characteristics from the SMR to explore the risk factors for visual acuity (VA) below ≤ 35 letters of the Early Treatment Diabetic Retinopathy Study (ETDRS) due to nAMD during a two-year follow-up. Methods: This study evaluates 6142 treatment-na{\"i}ve eyes, with focus on a subgroup of 780 eyes with final VA outcome of ≤ 35 letters, regarding differences of baseline characteristics, change of VA, number of injections and choice of drug to predict visual outcome. Results: Patients with final VA ≤ 35 letters were older; p < 0.0001, and received fewer injections, 6.2 ± 3.8 vs. 8.7 ± 5.4; p < 0.00001. Only 4{\%} of all patients with ≥ 70 letters baseline VA decreased to a final VA of ≤ 35 letters. The two groups with a final VA of ≤ 35 letters and VA > 35 letters presented the following baseline lesion locations; p = 0.001; 61{\%} vs. 57{\%} subfoveal, 18{\%} vs. 21{\%} juxtafoveal and 4{\%} vs. 6{\%} extrafoveal. Lesion size, in the group with final VA ≤ 35 letters, was 2805 ± 2093 μm vs. 2440 ± 1637 μm in the group with a VA of > 35 letters; p = 0.005. A logistic regression analysis including baseline VA, best- or worse-seeing eye, age, membrane size, membrane location, symptom duration showed VA; p = < 0.0001, best- or worse-seeing eye; p = 0.026, age; p = < 0.0001, and membrane size; p = 0.002 to predict a decline of VA within 2 years. Conclusions: In eyes treated for wet AMD and studied for 2 years, 12.7{\%} of eyes declined to a final VA of ≤ 35 letters. Visual acuity, worse-seeing eye treated, age and membrane size turned out as the baseline characteristics that had significantly influenced visual decline to ≤ 35 letters during the two-year follow-up.",
