[Vitreous haemorrhage associated with persistent hyaloid artery].

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.
