Benign idiopathic haemorrhagic retinopathy.
OBJECTIVE
To describe a new condition characterised by an unusual unilateral idiopathic haemorrhagic retinopathy.


METHODS
A review is presented of patient histories from 5 patients with acute-onset unilateral idiopathic haemorrhagic retinopathy, including results of ophthalmological, haematological and fluorescein angiographic examinations.


RESULTS
All patients had an extensive deep blot haemorrhagic retinopathy without significant vascular signs or abnormal optic discs. In 4 cases the haemorrhage was sufficiently severe to break through into the vitreous. Fluorescein angiography demonstrated normal arteriovenous flow, without capillary non-perfusion, vessel or disc leakage. Disc swelling, macular oedema and cotton wool spots were not seen at any stage in these patients. All patients recovered the visual acuity in the affected eye by 4 months. Systemic examination in all cases was unremarkable.


CONCLUSIONS
This distinct and rare form of retinopathy is important to define since it has a good prognosis without treatment.
