Abstract
Three human skulls showing duplication of the optic canal are reported. Two had bilateral duplication while one had duplication on one side only. The measurements of the whole canal were within the range of normal. Septa of variable thickness separated the main and the accessory canals in these skulls and the skulls also showed a tendency to excessive bone formation.
