Yellow Corneal Ring Associated with Vitamin Supplementation for Age-Related Macular Degeneration

“…The location and color of the corneal rings are similar to those reported in three patients with hypercarotenemia secondary to massive β-carotene consumption with serum levels of β-carotene ranging from two to eight times the upper limit of normal by Rahmani et al . 15 Previously, peripheral corneal rings have not been reported in clinical trials with β-carotene supplementation (Yoser DSL, Heckenlively JR. The appearance of retinal crystals in retinitis pigmentosa patients using beta carotene.…”
