Study Summary

The primary objective of the study is to assess the efficacy of aflibercept compared to laser in patients diagnosed with retinopathy of prematurity (ROP). The secondary objectives of the study are to assess the need for a second treatment modality, to assess the recurrence of ROP in the study and to assess the safety and tolerability of aflibercept.

Primary Outcome

For participants with both eyes enrolled in the study, both eyes must have met the endpoint. Participants with only one study eye enrolled were responders if the respective eye responded.
