Retinal periphlebitis after hormonal treatment

: Two cases, those of a man and a woman, developed retinal periphlebitis after hormonal treatment for infertility and contraceptives, respectively. Both had a unilateral severe decrease in visual acuity, and a central scotoma and defect in color vision were also present. The fundus had retinal edema, especially of the macula, a hyperemic disc with blurred margins, normal arteries, congested veins, and marked sheathing along the main veins, with retinal hemorrhages in the inferior half of the retina. Fluorescein angiography showed a delayed filling of the veins in the affected retina and late staining of these veins. Since there was severe visual impairment in each case, systemic adrenocorticosteroids were administered, and a rapid improvement in visual acuity occurred. In one patient, a trace Marcus-Gunn sign, a few small paracentral scotomas, and a defect in color vision were permanent sequelae.
