When a child was born too early, it is more likely to develop an alteration of its visual function than in the case of term birth. Significant visual disturbances are found in 3% of children born prematurely, but visual impairment can be very severe, up to the loss of vision in case of retinopathy of prematurity (ROP) in the most immature infants. The introduction of screening surveillance systems, such as WINROP software, might reduce the need for stressful eye examination in low risk neonates. This retrospective study aimed at validating the WINROP algorithm in a cohort of premature infants, born below 32 weeks of gestation, who had systematic eye examination for ROP screening over 4 year period.

Inclusion Criteria:

• All infants born below 32 weeks gestation within the study period
• At least one eye examination recorded by Retcam

Exclusion Criteria:

• Any ophthalmic abnormality
• Any genetic abnormality

All infants, born from July 2012 to July 2016, from 24 to 32 weeks gestation had hospitalized in our level III NICU having had eye examination up to 40 weeks post menstrual age.
