Acute annular outer retinopathy: report of four cases.

PURPOSE

To describe the clinical findings and course in four patients with acute annular outer retinopathy.

METHODS

Four patients were evaluated during the course of acute annular outer retinopathy, and the historical and clinical findings were retrospectively collected.

RESULTS

Four healthy patients developed the acute onset of visual field loss associated with a localized, white annular outer retinopathy. All patients were caucasian; two were women, aged 29 and 32 years, and two were men, aged 71 and 79 years. The mean follow-up was 3.9 years (range, 1 to 6 years). On presentation, four eyes had an irregular, incomplete, peripapillary, annular band of gray-white, deep retinal opacification with visual

CONCLUSIONS

These four cases of acute annular outer retinopathy expand our knowledge of this disorder. Acute annular outer retinopathy may be a distinct entity or it may represent a variant of acute zonal occult outer retinopathy retinopathy. As more cases are recognized, the characteristic features of the disease spectrum, the etiology, and treatment options may be better elucidated.
