Postoperative hyphema due to persistent tunica vasculosa lentis in glaucoma associated with neurofibromatosis—a case report

Abstract

An 8-month-old girl referred from her pediatrician with a diagnosis of neurofibromatosis type 1 (NF1) presented with an enlarged cloudy cornea of the left eye and a swollen left side of the face. Her left eye had intraocular pressure (IOP) of 21 mm Hg, corneal diameter of 16 mm, ectropion uvea, cup:disk ratio of 0.9, axial length of 28.06 mm, and S-shaped upper lid deformity. Uneventful combined trabeculotomy-trabeculectomy with mitomycin C was performed. On postoperative day 1, there was a new total hyphema that persisted for 2 weeks. An anterior chamber washout was performed, revealing the source of bleeding to be a persistent tunica vasculosa lentis along the zonules of the lens. Viscotamponade was performed, and the corneal wounds were closed, with the ocular tension slightly elevated. Bleeding did not recur for the following 5 months, and IOP was controlled until final follow-up.
