Persistent tunica vasculosa lentis (PTVL) results from the failure of the regression of the primary hyaloid vasculature surrounding the developing lens in utero and occurs in >90% of the infants born <36 weeks due to the deficiency of Wnt7b and angiopoietin 2.[1] It may be associated with a shallow anterior chamber, cataract, elongated ciliary processes, and microphthalmos.[2] The treatment varies from observation to lensectomy and fibrovascular retrolenticular membrane removal, though anti-Vascular endothelial growth factor (VEGF) has been tried. Here is a 29-year-old male who had a visual acuity of 20/30 in the right eye with retrolenticular fibrovascular membrane. The fundus was normal with a completely vascularized retina in the periphery [Figure 1]. | Figure 1: Retrolenticular fibrovascular membrane with prominent vessels extending close to the center of the lens
