Three Cases of Exotropic Moebius Syndrome

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Surgery

Background:

• Moebius syndrome presents with congenital facial palsy and limited horizontal eye movement.
• Exotropic strabismus is an uncommon manifestation of Moebius syndrome.
• Surgical outcomes for the exotropic pattern in Moebius syndrome are not well-documented.

Purpose of the Study:

• To report surgical outcomes in three cases of exotropic Moebius syndrome.
• To evaluate the efficacy of combined lateral rectus weakening and medial rectus strengthening.
• To highlight the importance of managing associated dry eye.

Main Methods:

• Surgical approach involved maximal weakening of the lateral rectus muscles.
• Simultaneous strengthening of the medial recti muscles was performed.
• Post-operative management included measures for severe dry eye.

Main Results:

• Significant improvement in exotropia was observed following the surgical intervention.
• The described surgical technique effectively addressed the outward deviation of the eyes.
• Management of dry eye was crucial for patient comfort and surgical success.

Conclusions:

• Maximal lateral rectus weakening combined with medial rectus strengthening is an effective surgical strategy for exotropic Moebius syndrome.
• This surgical approach can significantly improve exotropia in affected patients.
• Addressing severe dry eye is an essential component of comprehensive care for these patients.
