Summary
In routine eye examination of a 32-year-old male patient an annular macular dystrophy
was noted in absence of distinctive visual complaints.
Visual acuity was 20/20, the photopic and scotopic electroreti-nograms were normal.
The ring scotoma in perimetry and the macula finding in ophthalmoscopy corresponded
to the fluorescein angiographic pattern. Color vision deficiency was only mild without
any predominant axis of confusion.
Benign concentric annular macular dystrophy is rarely described in literature. Differential
diagnosis includes all ‘bull's eye’ conditions.
