Answer: Wavy and elevated vascularized line (ridge) between vascular and avascular retina with tortuous vessels.
Figure legend: Purple arrow – Tortuous vessels (plus disease). Blue arrow – ridge between vascular and avascular retina.
Dilated Fundus Exam (DFE) Findings:
In the left eye (above), there is normal retinal vasculature that extends into Zone II with moderate tortuosity and plus disease. The macula is not distorted. A three-dimensional vascular ridge is seen between the vascular and avascular retina. Neovascularization is also observed.
Findings in the right eye (below) are similar to the left eye and represent a more severe form of stage III ROP with the presence of vitreous hemorrhage.
