Severe Heavy Eye Syndrome With Esotropia and Hypertropia in a Female With Congenital Monocular Anophthalmia

Heavy eye syndrome, (HES) known as myopic strabismus fixus is a cause of acquired esotropia in the setting of high axial myopia.[1,2] Patients present with esotropia due inferior shifting and compression of the lateral rectus against the orbital wall, leading to reduced abduction and increased infraduction.[3] They often present with accompanying hypotropia secondary to nasal displacement of the superior rectus.[3] We hereby present a case of HES presenting with esotropia and hypertropia rather than hypotropia in the only eye of a female with congenital monocular anopthalmos.
