Preterm eye study pulled before it began
NCT ID NCT05699668
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study was designed to see if preterm children (born at or before 28 weeks) have differences in their retinal blood vessels compared to full-term children. Researchers planned to use a non-invasive imaging device called OCT angiography to measure blood vessel density. However, the study was withdrawn before enrolling any participants, so no results are available.

Inclusion Criteria: Premature group: \- Any child aged 5 to 15 years born before or at 28 SA (with or without BPD), followed or not at the Creteil's hospital intercommunal Control group: * Any child aged 5 to 15 years born ≥ 38SA, consulting ophthalmology at the Creteil 's hospital intercommunal. * Acceptance to participate in the protocol * Child living near the Creteil's intercommunal hospital * Affiliated to a social security system Exclusion Criteria: all groups * Neurobehavioral disorder or psychomotor delay that does not allow the examination to be performed * Presence of a POR with zone I involvement or having received IVT of anti-VEGF (as it may directly modify the OCT-A parameters) * Pre-existing retinal pathology: macular scarring of any etiology, retinal vascular alterations such as sickle cell disease, diabetes. * Pre-existing optic nerve pathologies: glaucoma, coloboma, tumors. * Chronic respiratory pathologies other than BPD (i.e. not associated with prematurity): cystic fibrosis, DDB... * General pathology unrelated to prematurity that may have a retinal impact: e.g. respiratory diseases other than BPD * Participation in an interventional study in ophthalmology * A history of hyperthermic convulsions in infants or epilepsy, which contraindicates the use of eye drops.
