Canthaxanthine retinopathy.
BACKGROUND
A 42-year-old white female complaining of decreased vision was examined and small golden particles were found in the macular regions of both eyes. It was ascertained that the patient had been using an oral bronzing agent, canthaxanthine (Orobronze), for the previous 10 years.


METHODS
The method of deposition of these crystalline particles and their possible sequela are presented. The differential diagnosis of this condition is also described.


RESULTS
In this case a crystalline retinopathy was induced by the oral ingestion of a bronzing agent.


CONCLUSIONS
Although the gold-like particles have no visual consequences, it is important for the clinician and the patient to be aware of their etiology.
