  1. SD = Standard Deviation, ETDRS = Early Treatment Diabetic Retinopathy Study, *In the discovery cohort, one optic-disc area is equal to 2.54 mm2, based on an optic disc diameter of 1.8 mm, +In the replication cohort optic disc measurement is based on each patient optic disc area, NA = Not available, ^Non-responders classified as those who showed loss of ≥5 EDTRS letters VA from baseline; all remaining patients were classified as responders. For 303 patients, Snellen visual values were first converted into approximate ETDRS letters using a chart that has all three measurement to read the equivalent number of ETDRS letters. It is based on formula ETDRS letters = 85 − ((−(logSnellen))/0.02)40.
