Outcome Measures

Primary Outcomes (1)

  • Proportion of eyes with a ≥ 2-step improvement in the ETDRS Diabetic Retinopathy Severity Scale (DRSS) score

    Baseline ETDRS DRSS: None (level 10); Mild to moderate nonproliferative DR (levels 14, 15, 20, 35, and 43); Moderately severe/severe nonproliferative DR (levels 47 and 53); Mild/moderate/high-risk/advanced proliferative DR (levels 61, 65, 71,75, 81, and 85)

    1 year

Secondary Outcomes (3)

  • Change from baseline in CRT (central retinal thickness)

    1 year

  • Mean change from baseline in best-corrected visual acuity (BCVA)

    1 year

  • Proportion of eyes that meet the protocol-defined failure criteria

    1 year

Study Arms (2)

Ranibizumab

EXPERIMENTAL

Participants received 0.5mg intravitreal ranibizumab injection

Drug: Ranibizumab

Sham-injection

SHAM COMPARATOR

No drug involved in the sham procedure; patient's eye is anesthetized and a syringe without needle gently pressed on the conjunctival surface to simulate the force of an actual injection

Procedure: No drug

Interventions

Participants in arm Ranibizumab will receive ranibizumab injection every 4 weeks for the first 3 months, followed by re-injections every 3 months until 1year

Also known as: Lucentis
Ranibizumab
No drugPROCEDURE

Participants in arm Sham-injection will receive sham injection every 4 weeks for the first 3 months, followed by re-injections every 3 months until 1year.
