“…[14] For diagnosis, slit-lamp examination, fundus examination, fluorescein angiography (FAG), OCT and Doppler ultrasound have been used. [3-8, 13, 15] Gonçalves et al [4] and Chen et al [5] Various mechanisms such as the traction force during the rapid eye movement phase of sleep [5], external trauma to the globe [4,16], and spontaneous development [6] have been reported. In our case, the mechanism of the occurrence of VH from the PHA is unclear.…”

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.

“…This was probably the result of a posterior vitreous detachment, which was seen by biomicroscopy. In previous reports, haemorrhages of a hyaloid artery have been explained by various mechanisms, such as rapid eye movements during sleep [1], due to external trauma to the globe [2], or considered to be spontaneous [3,4].…”

“…The presence of active blood flow in the postpartum hyaloid system is rare. In consequence, haemorrhage from a hyaloid artery has rarely been reported [1][2][3][4].…”

Abstract. Purpose: To report ocular complications of a persistent hyaloid artery. Methods: We studied eight patients with persistent hyaloid artery. Results: Seven patients showed strabismus and very low visual acuity (< 0.12) of one eye. Despite correction of refractive errors, cataract surgery and occlusion therapy for amblyopia, visual acuity had not improved in these cases. Four patients showed nystagmus. Four had progression of unilateral cataract. In two cases, a 24-year-old woman and a 4-months-old boy, a vitreous haemorrhage had occurred due to rupture of a hyaloid artery, in the woman's case probably due to a spontaneous posterior vitreous detachment. Conclusion: A persistent hyaloid artery may be associated with strabismus, cataract, amblyopia and nystagmus. Despite amblyopia treatment, the prognosis of visual acuity of the involved eye is unfavourable. A persistent hyaloid artery may cause vitreous haemorrhage.

“…Persistence of the hyaloid vascular system occurs in only 3% of full-term infants but in 95% of premature infants (Jones, 1963) and can be associated with prepapillary hemorrhage (Delaney, 1980). Anomalies involving inadequate regression of the embryonic hyaloid vascular system occur in more than 90% of infants born earlier than 36 weeks of gestation and in over 95% of infants weighing less than five pounds at birth (Renz and Vygantas, 1977).…”
