An office-based scale for assessing control in intermittent exotropia.

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Strabismus Management

Background:

• Intermittent exotropia progression lacks standardized measurement criteria.
• Assessing control levels is crucial for managing this common pediatric eye disorder.

Purpose of the Study:

• To prospectively evaluate a novel scale for assessing the level of control in children diagnosed with intermittent exotropia.
• To establish a quantifiable method for measuring control in pediatric intermittent exotropia.

Main Methods:

• Prospective evaluation of 30 pediatric patients (<14 years) with intermittent exotropia.
• Utilized a new scale to assess control for both distance and near fixation (0-5 each).
• Combined distance and near scores to obtain an overall control score (0-10).

Main Results:

• The study included 30 patients with a median age of 72 months.
• Distance control was consistently worse than or equal to near control in all patients.
• Observed control scores ranged from 0-5 for distance, 0-4 for near, and 0-8 overall (median 3).

Conclusions:

• The new scale is easily applicable in clinical settings for assessing intermittent exotropia control.
• This tool effectively characterizes the diverse range of control levels in pediatric patients.
• Provides a valuable method for quantifying control in intermittent exotropia management.
