A yellow ring-shaped macular reflection.
OBJECTIVE
To describe a yellow ring-shaped reflection in the macula of healthy subjects observed with a common indirect ophthalmoscope.


METHODS
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.
