Understanding and Provision of Preconception Care By General Practitioners

41 red light. There was no difference in severity of ROP (<27 weeks p=0.463; ≥27 weeks p=0.558) or requirement for laser treatment (<27 weeks p=1.00; ≥27 weeks – no laser treatment in either group). Survival in the 670 nm red light treatment group was 100% (41/41) vs 89% (40/45) in untreated infants (p=0.057). Conclusions: Randomisation to receive 670nm red light within 24-48 hours after birth is feasible. A large multicentre study with 700 neonates in each arm is required to determine whether 670 nm red light has an influence on the development of ROP and survival outcomes.
