AZRAK, C. et al. Vitreous haemorrhage associated with persistent hyaloid artery. Arch Soc Esp Oftalmol [online]. 2011, vol.86, n.10, pp.331-334. ISSN 0365-6691.

Introduction: Haemorrhage from an entire persistent hyaloid artery (PHA) is an uncommon anomaly. Case report: A 52 year old female presented with blurred vision in her amblyopic eye. Biomicroscopy revealed a blood filled PHA which was inserted in the posterior crystalloid. Ophthalmoscopy showed a mild vitreous haemorrhage. A tubular structure showing a hypo-reflexivity inside the PHA was able to be analysed using optical coherence tomography (OCT). However, Doppler ultrasound did not detect the presence of active blood flow within it. Conclusions: The performance of non-invasive imaging tests such as the OCT and Doppler ultrasound may be useful in the study of vitreous haemorrhage associated with PHA.
