Visual acuity in a 17-year-old girl who took norethindrone with mestranol (Ortho-Novum) for eight months decreased to 6/9 (20/30) in the left eye. Ophthalmoscopically, retinal edema was temporal to the disk and white plaques were in each of two branches of cilioretinal artery. A superior centrocecal scotoma corresponding to the area of edema was present. After the patient discontinued use of the drug, visual acuity improved to 6/6 (20/20).
