Indocyanine green angiography in enlarged blind spot syndrome.

PURPOSE: To report the indocyanine green angiography findings in a case of acute idiopathic blind spot enlargement syndrome.

METHOD: The patient underwent ophthalmologic examination with fluorescein angiography and indocyanine green angiography.

RESULTS

A monocular enlarged blind spot was found on automated perimetry; fluorescein angiography showed a hypofluorescent peripapillary atrophic area and indocyanine green angiography highlighted diffuse, small hypofluorescent spots scattered throughout the posterior pole. Visual field defects and indocyanine green angiography abnormalities resolved over 4 weeks.

CONCLUSION

Indocyanine green angiography in acute idiopathic blind spot enlargement syndrome showed many lesions not visible with fluorescein angiography, indicating a choroidal involvement reaching not only the peripapillary area but the entire posterior pole.
