[Acute zonal outer occult retinopathy].

CASE REPORT
In May 2001 a 10-year-old boy, examined 3 months after the development of a large temporal scotoma in the right eye, was diagnosed with photopsia. The fundus appeared normal, visual field examination revealed a large temporal defect and, in July 2001, electroretinography (ERG) was nonrecordable. The left eye was normal. The field defects and ERG abnormality remained 4 years later, and the fundus developed a sharply demarcated zone of atrophy of the RPE.


DISCUSSION
We report a typical case of acute zonal occult outer retinopathy (AZOOR). Although rare, its symptoms are variable, and its shape is not characteristic, making it difficult to make the correct diagnosis.
