PURPOSE: To evaluate the surgical results of Möbius syndrome esotropia following bilateral medial rectus recession with and without bilateral Hummelsheim procedure.
METHODS: The medical records of patients with Möbius syndrome operated on by a single surgeon from 1993 to 2022 were studied retrospectively. For each patient, age, sex, and ocular deviation before and after surgery were retrieved. Success was defined as a horizontal deviation of up to 15Δ and vertical deviation of <10Δ.
RESULTS: Eleven patients were included. Average patient age at the time of surgery was 4 years. Eight patients with esodeviation up to 70Δ underwent bilateral medial rectus recession; 3 patients with esotropia >70Δ underwent recession plus bilateral Hummelsheim procedure. The mean esodeviation before surgery was 52.5Δ in the first group and 86.6Δ in the second group. The mean horizontal deviation at early follow-up was esotropia of 7.4Δ in the first group and of 15Δ in the second group. The early success rate was 87% in the first group and 67% in the second group. Long-term follow-up revealed exoshift in 43% of the patients in the first group and all 3 patients in the second group.
CONCLUSIONS: In our small patient cohort of patients with Möbius syndrome, bilateral medial rectus recession corrected esodeviations of up to 70Δ. In more severe cases (>70Δ), adding bilateral Hummelsheim procedure was beneficial.
