Progressive changes in the fluorescein and indocyanine green angiogram in acute idiopathic maculopathy

Abstract

Aims/background: To report progressive changes in the fluorescein and indocyanine green angiograms of a patient with acute idiopathic maculopathy (AIM).

Methods: Over a two-year period, the patient underwent repeated ophthalmoscopic examinations and fluorescein (FA) and indocyanine green (ICG) angiography.

Results: The patient presented with subretinal neovascularization in his right eye. He developed recurrences after laser photocoagulation and surgical removal of the neovascular complex. One year later, he experienced a sudden loss of vision in his left eye with a maculopathy consistent with AIM. The maculopathy resolved after two weeks with poor vision. During the acute stage, FA showed lobular hyperfluorescence in the early phase and pooling in the late phase of the angiogram. In the resolved stage of the disease, FA showed irregular window defects and blockage. ICG revealed late hyperfluorescence of the macula in the acute stage. In the resolved stage of the disease, early hypofluorescence was noted in the ICG, which persisted throughout the late phase.

Conclusion: This patient had poor vision in his right eye as a result of subretinal retinal neovascularization and poor vision in his left eye from a severe form of AIM. FA and ICG differed markedly during the acute and resolved stages of AIM. All cases of idiopathic subretinal neovascularization should be carefully evaluated to exclude AIM as the primary disease.
