Unilateral rectus muscle recession in the treatment of Duane syndrome.

Purpose: To determine the outcome of unilateral single horizontal rectus recession surgery in patients with Duane retraction syndrome.

Methods: A retrospective review was conducted of 27 medical records of patients with Duane syndrome who underwent unilateral medial rectus recession for esodeviations and lateral rectus recession for exodeviations. The criteria for evaluating surgical success included improvement of abnormal head position, reduction of strabismus deviation, and preservation or improvement of stereoacuity.

Ophthalmologic abnormalities in Mowat-Wilson syndrome and a mutation in ZEB2.

Mowat-Wilson syndrome is a genetic disorder characterized by a distinct facial appearance, moderate-to-severe mental retardation, microcephaly, agenesis of the corpus callosum, Hirschsprung disease, congenital heart disease, and genital anomalies. Ophthalmological abnormalities have been rarely described in patients with this condition which is caused by mutations in the ZEB2 gene. We report a 9-year-old female with this syndrome who has severe ocular abnormalities including bilateral microphthalmia, cataract, and retinal aplasia.

Filter placement for duplicated cava.

Anatomic variations of the inferior vena cava (IVC) are found in 3-5% of the population. IVC duplication is a well-known anatomic variation that is important when relevant procedures are being planed. Therefore, the identification of IVC anomalies should be checked prior to pertinent interventions.
