Strabismus in ptosis.

Two hundred twenty-six consecutive surgical ptosis cases were carefully evaluated to establish the incidence of strabismus in ptosis. The overall incidence of strabismus in surgical ptosis patients was found to be 36%. Most remarkable were the findings in 113 congenital ptosis patients; 32% of these patients were found to have strabismus. Only 44% of these patients had entities previously described associating strabismus with ptosis. It is postulated that in four of the congenital ptosis patients (3.5%), strabismus developed as a result of their ptosis. In one of these patients, strabismus and amblyopia developed while the patient was being observed prior to ptosis surgery. This study demonstrates the need for careful ocular motility evaluation in all patients with ptosis. Ocular motility evaluation and follow-up is especially important in congenital ptosis, where the ptotic lid may, in fact, precipitate strabismus and amblyopia.

Amblyopia in ptosis.

Amblyopia can result from strabismus, anisometropia, media opacities, and congenital disorders such as nystagmus. Complicated forms of ptosis (ie, associated with neurofibroma or hemangioma) are also known to cause amblyopia. A previously unconfirmed cause of amblyopia is uncomplicated ptosis. We carefully examined 123 consecutive surgical ptosis patients with uncomplicated congenital or early acquired ptosis. Twenty-five cases of amblyopia (20%) were seen. Four cases (3.2%) were thought to be caused by the ptosis. In two of these cases (1.6%), the amblyopia was directly attributed to the ptosis. In one of the remaining two cases, exotropia and amblyopia developed on the ptotic side while the patient was being observed for the ptosis. In another patient, a progressively increasing cylindrical refractive error and amblyopia developed, which were attributed to the ptosis. We recommend careful evaluation of cases of congenital ptosis for the detection and treatment of amblyopia.
