Any variations in the origin of the ophthalmic a. are uncommon and well-explained by the comparative anatomy and human embryology. A unique case is reported of an ophthalmic a. arising from the middle meningeal a. associated with an occlusion of the central retinal a. Embryologic variations which can give such an unusual origin are discussed. Although this association may be fortuitous, we consider that an unusual origin of the ophthalmic a. could be a further factor for an occlusion of the central retinal a.
