Regional uveal response to increased nutritional needs in the retinal zone of the developing eye demonstrated in an eye with retinoblastoma.
The outer layers of the normal retina depend on indirect nutrition originating in the choriocapillaris and supplied to the retina by way of the pigment epithelium. An eye with exophytic retinoblastoma is used to demonstrate increased vascularity and tissue substance in the adjacent choroid believed to be indirectly induced by a regional increase in nutritional requirements in the retinal zone of a developing eye.
