Ciliary body arteriovenous malformation?

This article states that high-frequency ultrasound biomicroscopy (UBM) has been proven useful in the diagnosis and management of anterior segment pathology. A case of probable arteriovenous malformation (AVM) of the ciliary body that was imaged with UBM is described. A 33-year-old male presented with abnormal redness in the left eye associated with symptoms of itch and discomfort for 5 years. He was most disturbed by the cosmetic appearance of persistent dilated vessels. Fundus examination showed normal retinal vessels. A provisional diagnosis of AVM over the left nasal conjunctiva was made and was initially managed expectantly. The iris configuration was normal. The eye was treated with topical antibiotics and steroids postoperatively. VA was unchanged postoperatively. The patient was happy with the cosmetic result and no recurrence of dilated vessels occurred.
