Congenital entropion and hypotropia secondary to duplication of the inferior rectus muscle.

Congenital anomalies of the extraocular muscles apart from congenital fibrosis are relatively rare. Duplication of extraocular muscles is a particularly rare congenital anomaly that has been rarely reported in the literature. We present a case of unilateral congenital entropion and hypotropia resulting from duplication of the inferior rectus muscle.
