Hard exudates severity at baseline, month 1 and month 3. The figure shows the percentage of eyes in each category in both (A) DR and (B) BRVO groups. Hard exudate severity categories were defined according to Early Treatment Diabetic Retinopathy Study criteria as absent (no hard exudate present), minimal (> 0–0.1 mm2), mild (> 0.1–0.5 mm2), moderate (> 0.5–2.5 mm2), and severe (> 2.5 mm2)
