Toxoplasmic retinochoroiditis: new insights provided by indocyanine green angiography.

Abstract

To analyze features of indocyanine green angiography associated with recurrent toxoplasmic retinochoroiditis. Indocyanine green angiography was performed according to a standard protocol and correlated with clinical signs and fluorescein angiography in 12 eyes of 12 consecutive patients with recurrent toxoplasmic retinochoroiditis. In 10 of 12 eyes with recurrent toxoplasmic retinochoroiditis, indocyanine green angiography showed multiple satellite dark dots not seen on fluorescein angiography or clinical examination of the fundus. Indocyanine green angiography shows that recurrent toxoplasmic retinochoroiditis is more widespread than clinically visible lesions indicate. Indocyanine green angiography is useful in assessing the extent of involvement of recurrent toxoplasmic retinochoroiditis and the evolution of lesions and might also provide insights into the pathophysiology of the disease.
