The authors describe a 51-year-old woman who was taking canthaxanthin for tanning purposes for 7 years. Three years after cessation of this agent, she presented with asymmetric crystalline retinopathy affecting both eyes. She was lost to follow-up, and upon returning 4 years later, the crystalline retinopathy persisted but the number of crystals had decreased. Using swept-source optical coherence tomography, the authors showed that the crystalline retinopathy affected all retinal layers. In addition, retinal pigmented epithelial detachments were present suggesting persistent damage caused by the canthaxanthin. [Ophthalmic Surg Lasers Imaging Retina. 2020;51727-731.].Vitamin A is an important component of the visual cycle, and its deficiency causes a retinal degeneration that may be reversed with retinol supplementation. Here, the authors present a patient with vitamin A deficiency and rod-mediated retinopathy who was found to have multiple anti-retinal antibodies that gradually dissipated after vitamin A supplementation. This interesting case suggests the possibility that the photoreceptor degeneration induced by vitamin A deficiency may lead to transient immune exposure to retinal antigens and development of anti-retinal antibodies. [Ophthalmic Surg Lasers Imaging Retina. 2020;51723-726.]. The management of premacular hemorrhage secondary to non-accidental trauma (NAT) is unclear. The authors describe the outcomes of NAT infants referred for surgical evaluation of premacular hemorrhage. Retrospective institutional review board-approved case series between 2000 and 2019 of vision-threatening premacular hemorrhage (sub-hyaloid or sub-internal limiting membrane hemorrhage without vitreous hemorrhage) in NAT infants. Time to hemorrhage resolution, vision, and
