Background and Aims
Retinopathy of prematurity (ROP) is a disease of low gestational age and low birth weight infants. Screening is required to identify patients who require treatment to prevent the development of a potentially blinding disease. We undertook an audit of the ROP screening process within a level 3 neonatal unit to assess network guideline adherence and screening patterns. 
Methods
Eligible babies between January 2017 and January 2018 were identified including babies born locally, and those from within the wider network. Each record was reviewed to collect birth weight, gestational age, corrected gestational age, stage of ROP at each screen and treatment requirement. 
Results
Data was collected on 146 babies (total eligible = 233). Adherence to local guidelines was overall good; all babies were screened except two due to parental refusal. 
We had an incidence of ROP requiring treatment of 3% (published UK estimate 4%). Earlier gestation and low birth weight are associated with a worse grade of ROP (Figures 1 & 2). 7/146 babies required treatment with laser therapy or antiVEGF therapy after a mean of 4.7 screens (range 3-7 screens). The earliest CGA requiring treatment was 33 weeks. There were no adverse anatomical outcomes 1 month post-treatment. 
Conclusions
All babies who needed treatment were born at a gestational age of 25 weeks or less and weighed < 1000g. We suggest considering customised screening criteria informed by local audit given the morbidity associated with eye examinations.
