A yellow ring-shaped macular reflection.
PURPOSE: To describe a yellow ring-shaped reflection in the macula of healthy subjects observed with a common indirect ophthalmoscope. DESIGN: Observational case series. METHODS: Fundus photographs of the macula were acquired with a slit lamp and 90-diopter lens in 5 healthy subjects (age range, 23-50 years) at a perpendicular angle and at an oblique angle to the retina. RESULTS: The perpendicular fundus photographs showed a yellow ring-shaped reflection with a diameter of approximately 5 degrees. The oblique photographs had a dark red spot in the center. CONCLUSIONS: To our knowledge, this phenomenon has hitherto escaped attention in the literature. We conclude that the shape, size, and location of the yellow reflection are consistent with a cone origin. This observation may be used for diagnostic purposes.
