PURPOSE/ METHODS: We studied a case of crystalline retinopathy occurring after prolonged use of oral canthaxanthin. The patient was followed up for 38 months during which time she sustained a branch retinal vein occlusion in her left eye. RESULTS/ CONCLUSIONS: An asymmetric appearance to the crystalline deposition was noted with increased sedimentation seen in the left eye. Vascular alterations after a branch retinal vein occlusion may lead to local stasis that may exacerbate the development of canthaxanthin retinopathy.
