Indocyanine green angiography in isolated primary retinal arterial macroaneurysms.

Objective: 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.

Conclusions: 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.
