Abstract

Heterotopia of the macula, sometimes referred to as ectopic macula, is a distinct clinical entity which is characterized by the appearance of a pseudostrabismus occurring as a result of an exaggerated disparity between the visual and optic axes. The macula does not occupy its customary position which is 1.5 mm temporal to the optic axis; hence the visual axis is along a significantly different line. The etiology of heterotopia of the macula includes trauma, chorioretinitis, developmental causes, and incomplete or abortive retrolental fibroplasia. The authors experienced a case of pseudo-exotropia caused by heterotopia of the macula associated with cleft lip and palate.
