PURPOSE: The study was carried out to describe the indocyanine green angiographic findings in isolated primary retinal arterial macroaneurysms and their contribution to the diagnosis of this condition. METHODS: Fluorescein and indocyanine green angiography examination techniques were used to study isolated primary retinal arterial macroaneurysms in 8 consecutive patients with retinal or preretinal haemorrhage over a period of 12 months. RESULTS: The fluorescein angiography examination showed the macroaneurysm in four cases; pulsatility was not observed in any case. Indocyanine green angiography disclosed the macroaneurysm in six cases; pulsatility was observed in two cases. CONCLUSION: Indocyanine green angiography allows better visualization of arterial macroaneurisms in the first examination and therefore facilitates the diagnosis, follow-up and laser treatment of this vascular abnormality.

PURPOSE: To report choroidal vascular abnormality in unilateral Purtscher's retinopathy. METHODS: Fluorescein angiography and indocyanine green angiography with a scanning laser ophthalmoscope were used to examine a 19-year-old man four days, three months, and five months after sustaining an injury in a car accident. RESULTS: Indocyanine green angiography showed an area of choroidal hypofluorescence that continued to be present up to five months after the accident. CONCLUSIONS: Choroidal vasculature may be affected in Purtscher's retinopathy. Disorder in the choroidal microcirculation could be an additional cause of the resulting poor vision observed in some patients with Purtscher's retinopathy.
