OCT angiography of persistent hyaloid artery: a case report

Abstract

Background A persistent hyaloid artery is a rare fetal remnant. Several complications such as amblyopia, vitreous hemorrhage, and retinal detachment have been reported. Here, we present a case of vitreous hemorrhage with a persistent hyaloid artery. Case presentation A healthy 16-year-old male presented with blurred vision in his left eye. Vitreous hemorrhage occurred and absorbed spontaneously. Slit-lamp examination demonstrated a Mittendorf’s dot and fundus examination revealed a persistent hyaloid artery. Optical coherence tomography (OCT) showed a Bergmeister’s papilla. The blood flow of the persistent hyaloid artery via the Bergmeister’s papilla was found by OCT angiography. Conclusion The persistent hyaloid artery should be considered as a cause of spontaneous vitreous hemorrhage of young healthy patient. The OCT angiography will be a useful noninvasive approach to confirm the patency of the persistent hyaloid artery.

“…Vitreous hemorrhage was reported in a case of posterior PFV whose OCTA demonstrated blood flow in Bergmeister's papilla. 43 OCTA may be useful in some patients for confirming the diagnosis and for further management. 43 Intraoperative Optical Coherence Tomography (Intraoperative OCT)…”

Paediatric vitreous haemorrhage secondary to clinically occult, anomalous hyaloid and peripapillary arteries demonstrated by OCT-A

“…It is possible that clinically occult, persistent anomalous artery remnants may explain some of these cases. Whilst OCT-A may demonstrate flow in clinically obvious hyaloid arteries [ 4 ], we recommend OCT-A of the optic disc for paediatric patients presenting with unexplained vitreous haemorrhage where media clarity permits. This may prevent the need for extensive investigations, for example, to exclude underlying vasculitic, septic or haematological disorders [ 5 ].…”

“…These complications are most likely to be seen at birth or within a few years after. PHPV is also one of the most common causes of infantile leukocoria [8], with a retrospective study demonstrating that strabismus represents not only a common complication of PHPV but also the cause of the initial diagnosis, accounting for 15.5% of all cases [9]. The diagnosis of PHPV is typically made based on the results of the B-mode ultrasound, optical coherence tomography (OCT), or Doppler ultrasound [10,11].…”
