Cureus 2020 Sep 23;12(9):e10605. Epub 2020 Sep 23.

Ophthalmology, Lily Hospitals Limited, Warri, NGA.

The surgical management of persistent fetal vasculature (PFV) is challenging and the visual outcome can be compromised by coexisting ocular pathologies and amblyopia. It can be considered for relief of retinal traction and improved cosmetic appeal when a squint or a posterior capsular cataract is present. In the case presented in this report, the intermittent exotropia improved from 45 to 30 degrees in one year, which suggests an improvement in binocular single vision. Read More
