A 6-month-old boy presented with exotropic strabismus. Results of slitlamp examination with fundus examination of the left eye (Figure, A) showed peripheral retinopathy with a temporal retinal band extending from the optic disc to the peripheral retina, raising concern for retinal detachment.
Magnetic resonance imaging results (Figure, B) showed a sheetlike thickening with a peripheral base and a free edge. This finding was not consistent with retinal detachment or persistent fetal vasculature but was consistent with a congenital retinal fold.
