Distinct Pattern Observed After Intermittent Exotropia Surgery: Characteristics of Patients Exhibiting Postoperative...

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Surgery

Background:

• Intermittent exotropia (IXT) is a common form of strabismus.
• Surgical correction aims to restore binocular alignment.
• Postoperative outcomes require careful monitoring for potential complications.

Purpose of the Study:

• To investigate a unique postoperative pattern following intermittent exotropia (IXT) surgery.
• To identify risk factors associated with delayed-onset consecutive esotropia.
• To analyze the clinical characteristics of patients developing esotropia post-IXT surgery.

Main Methods:

• Retrospective review of patients under 18 years old undergoing IXT surgery.
• Follow-up period of 2 years or more.
• Classification of delayed-onset consecutive esotropia based on postoperative alignment.

Main Results:

• Delayed-onset consecutive esotropia occurred in 6.4% of patients, approximately 4 months postoperatively.
• Risk factors included younger age, larger preoperative deviation angles, and bilateral lateral rectus (BLR) recession.
• Rebound esodrift was observed in other exotropia groups, sharing similar risk factors.

Conclusions:

• Delayed-onset consecutive esotropia is a notable postoperative pattern after IXT surgery.
• Early identification and management are crucial for optimal patient outcomes.
• Risk factors identified can aid in patient selection and postoperative care strategies.
