Best Corrected Visual Acuity (BCVA) was assessed during all study visits using best correction determined from protocol refraction at a starting test distance of 4 meters. VA measurements were taken in a sitting position using Early Treatment Diabetic Retinopathy Study (ETDRS)-like visual acuity testing charts. The overall BCVA score (number of letters read correctly by the patient) was calculated using the BCVA worksheet 0-100 letter score, with higher score indicating improvement in acuity. A positive change from baseline is a favorable outcome. BCVA assessments after start of alternative diabetic macular edema (DME) treatment in the study eye were censored and replaced by the last value prior to start of this alternative treatment.

The survey consisted of 25 items representing 11 vision related constructs (general vision, ocular pain, near activities, distance activities, social functioning, mental health, role difficulties, dependency, driving, color vision, peripheral vision) plus a single-item general health rating question. The score of each individual question ranged from 0 (worst) to 100 which indicated the best possible response. The composite score and score of each construct also ranged from 0 to 100 as they were calculated as total scores divided by the number of questions. The higher the values of total scores represented better outcome.
