Reappearance of excentric persistent fetal vasculature stalk following laser treatment in a patient with type 1 retinopathy of prematurity.

Abstract

In this report, we aim to present an unusual reappearance of hyaloidal artery remnant with atypical localization during the follow-up of an infant who underwent indirect laser photocoagulation for type 1 ROP. Retrospective case report. We report a case of reappearance of an eccentrically located hyaloidal stalk in the macular area during the follow-up period, 2 weeks after laser photocoagulation for type 1 ROP subsequently progressed to cause foveal distortion, which is successfully removed with a lens-sparing vitrectomy. To the best of our knowledge, there is no similar case in the literature. In the presence of fibrovascular proliferation extending into the vitreous, especially in premature infants, it should be kept in mind that this may be a reappearance of PFV and it may not always be located on the optic disc.
