Retinal nonattachment
HP:0007899
What it means
Retinal nonattachment is a developmental (congenital) condition in which persistent fetal blood vessels appear to proliferate more dramatically during infancy, causing complete perinatal detachment of the retina. This may occur during or shortly after neurogenesis, since the pathology is apparent at birth, and it may have a tractional basis, involving fibrovascular strands between the retina, posterior lens and hyaloid vessels.
