The authors describe a three-year-old girl with congenital unilateral restriction of elevation, associated with retraction of the globe and narrowing of the palpebral fissure. The pathogenetic possibilities are discussed; the presence of a vertical innervation anomaly, similar to Duane's syndrome, is postulated.
