• Registration Number: NCT06762067
• Lead Sponsor: Cairo University

Brief Summary

The study aims to explore the impact of mirror therapy on exodeviation control, near and far strabismus angles, and quality of life in intermittent exotropia control post strabismus surgery, as well as its effects on near and far strabismus angles.

Detailed Description

Strabismus is a common childhood disorder causing eye deviation, affecting life quality and cosmetic appearance. Early detection and management improve binocular function and psychosocial problems. Intermittent exotropia is a common type. Surgery is the most common method for correcting strabismus, but complications can be difficult to treat. Physical therapy programs are limited in treating strabismus after surgery, and adding mirror therapy to traditional treatments may help maintain surgery results. This thesis aims to decrease this knowledge gap and improve the treatment of strabismus.

Primary Outcome Measures

Name	Time	Method
Assessment of change of the exodeviation control	at baseline and after 3 months	The ophthalmologist examines participants' eyes while focusing on an accommodative target, determining their exotropia score. The scores range from constant to dissociated, with no exotropia unless dissociated and maximum score is 5 and minimal score is 0. the lower score is the better

Secondary Outcome Measures

Name	Time	Method
Assessment of change of the near strabismus angles	at baseline and after 3 months	the near strabismus angles will be measured by using prisms of different powers
Assessment of change of the far strabismus angles	at baseline and after 3 months	The prism cover test is a method used to measure the angle of deviation of a small-angle tropia. It involves covering the non-fixating eye with a prism oriented in the same direction as the deviation, blocking the fixating eye simultaneously. The strength of the prism is adjusted to prevent fixation shift and reduce deviation. Near and far strabismus angles are measured using prisms of varying powers. The measurement should be taken at 33 cm, 6 m, and occasionally at 60 m, and with or without corrective lenses.
Assessment of change of questions of Child and Proxy health related quality of life	at baseline and after 3 months	The final Child and Proxy health-related quality of life questionnaires for intermittent exotropia are designed to gather information about the concerns and difficulties faced by children and adolescents with this condition. The questionnaires are formatted for 5-7-year-old children, 8-17-year-old children, and PROXY children.
Assessment of change of questions of health-related quality of life questionnaire for Parents of children with intermittent exotropia	at baseline and after 3 months	Parents of children with intermittent exotropia often express concerns about their child's eyesight, including potential physical and psychological effects.
