Descriptive Information
Brief Title  ICMJE The Effect of Oculo-Motor Exercises in Intermittent Exotropia
Official Title  ICMJE Investigation of the Effect of Oculo-Motor Exercises in Intermittent Exotropic Children
Brief Summary In childhood strabismus, exotropia is most frequently seen with intermittent exotropia and convergence failure in the first decade of life. This situation adversely affects children's psychosocial development and creates worries about personal relationships and work life in their future lives. Patients' hesitant attitudes towards surgical treatment led to the out-of-surgery techniques such as exercise therapy. No studies have been found in the literature on the efficancy of the intermittent exotropia treatments with oculo-motor exercises. In our study, it was aimed to investigate the effects of oculo-motor exercises on intermittent exotropia in children.
Detailed Description 50 volunteer school-aged children between 2-17 years of age) were included in our study. Oculo-motor home exercise protocols were given to all participants for 2 sessions per day for 6 weeks, and regular phone calls were made once a week. Participants were assessed cycloplegic refraction by autorefractometry, corrected and uncorrected visual acuity by snellen chart, ocular motility test, near and distant alternating prism cover test, streopsis test and patient satisfaction levels by intermittent exotropia survery.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Intermittent Exotropia
  • Exercises
Intervention  ICMJE Behavioral: Oculo-Motor Exercises (OME)

Oculomotor Exercises (OME); The saccadic eye movement exercise included moving the eyes horizontally between two stationary targets while keeping the head still.

The smooth pursuit exercise included moving the target horizontally and tracking it with the eyes while keeping the head still.

The adaptation X1 exercise included moving the head horizontally while keeping the stationary target in focus.

The adaptation X2 exercise included moving the head and target in opposite directions horizontally while tracking the target with the eyes.

Study Arms  ICMJE Experimental: Oculo-Motor Exercises (OME)
10 repetitive four different oculomotor exercise protocols with eye stabilization were organized as home programs for 6 weeks, twice a day in the morning and evening each day of the week.
Intervention: Behavioral: Oculo-Motor Exercises (OME)
