ASYMMETRIC CANTHAXANTHIN RETINOPATHY

PURPOSE/METHODS: We studied a case of crystalline retinopathy occurrin g 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 appeara nce to the crystalline deposition was noted with increased sedimentati on seen in the left eye. Vascular alterations after a branch retinal v ein occlusion may lead to local stasis that may exacerbate the develop ment of canthaxanthin retinopathy
