ABSTRACT.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.
