Résumé
Vitreoretinal interface is consisted of posterior vitreous cortex, retina internal limiting membrane, and extracellular matrix between them. Basement membrane-like complex is formed in the interface. The interface in children is of much difference with that in adult. The adhesion of it is much tight in children. The posterior edge of vitreous base is closed to ora serrata. The retina internal limiting membrane is thin. But with age, the posterior margin of vitreous base extends posteriorly, internal limiting membrane thickens and its elasticity decreases, the adhesion in vitreoretinal interface weakens, and posterior vitreous detachment develops. To recognize fully the interface in children is of much importance for understanding the pathophysiology and treatment strategy of pediatric vitreoretinal diseases.
