Article Synopsis
- Synergistic divergence, or type IV Duane syndrome, is a congenital disorder marked by unusual eye muscle control leading to both eyes moving outward when trying to look to one side.
- A case study of a 23-year-old man highlighted his strabismus surgery to address a significant right exotropia and a left head turn developed for better vision since childhood.
- The surgery involved a combination of a 14 mm recession of the right lateral rectus and a 10 mm resection of the right medial rectus, suggesting this approach as an effective treatment for the condition.
: Monocular transposition of the inferior oblique muscle belly (IOMBT) effectively weakened mild to moderate inferior oblique overaction and corrected small primary position hypertropia. Now we aim to evaluate the efficacy of inferior oblique muscle belly transposition (IOMBT) in treating V pattern strabismus with upshoot in adduction.: This is a retrospective review of 13 patients with V pattern who underwent IOMBT procedure from January 2017 to December 2018.

Purpose: To evaluate the efficacy of transposition of the belly of the inferior oblique muscle in treating inferior oblique overaction with small angle hypertropia.
Methods: The medical records of 10 patients who underwent inferior oblique belly transposition from March 2014 to July 2016 were reviewed. Transposition of the inferior oblique muscle belly consisted of suturing the entire body of the muscle to the sclera 5 mm posterior to the temporal insertion of the inferior rectus muscle.

Orbital Dermoid Cyst Presenting with a Discharging Sinus Tract.

This report describes a case of orbital dermoid cyst presenting with a discharging sinus tract. The embryologic basis for orbital dermoids in general is discussed, as well as their typical presentation and management. In the current case, patient presentation and management were somewhat different because of signs of infection and a communicating sinus tract, both highly unusual for orbital dermoids.

The embryologic basis for this condition is discussed, as well as the epidemiology, typical presentation, and possible treatment modalities. After we excised the fistulas and intubated the nasolacrimal ducts in this patient, he experienced improvement in symptoms by report.

Design: Cross-sectional study.
Participants: Children ages 6 to younger than 48 months with and without clinical signs of NLDO.
Purpose: Our purpose is to report our experience with balloon catheter dilation of the nasolacrimal duct after failed probing for congenital nasolacrimal duct obstruction.
Methods: We undertook a retrospective chart review. Patients who were enrolled had symptoms of persistent nasolacrimal duct obstruction after simple probing and irrigation.
