Persistent Tunica Vasculosa Lentis

of plus disease, significant vasoconstriction may be present. If the vasculature is very immature, i. e., limited to zone I or posterior zone II disease, the presence of vasoconstriction should prompt weekly follow-up examinations. Anterior segment changes should also be carefully evaluated as the presence of a persistent and dilated tunica vasculosa lentis and overt hyperemia of the iris vessels are a clear indicator of severe retinal disease that may require treatment (Fig. 5.4).The findings must be documented in a written report specifying the location, extent, and severity of the disease, and also recommendations as to follow-up or therapy. A scheme for follow-up examinations in the presence of ROP is given in Tables 5.9 and 5.10. Care must be taken that recommended follow-up examinations also take place once the infant is discharged from the NICU.
