About this study

Exotropia is classified as Primary which includes constant and intermittent exotropias. Secondary XT include Sensory and consecutive XT. Management for IXT consists of non-surgical and surgical treatment. There is some controversy regarding the optimal surgical method varying between bilateral lateral rectus recession (BLR), unilateral lateral rectus recession-medial rectus resection (RR) and bilateral medial rectus resection (BMR).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients above age of 5 years with concomitant Exotropia of (40-55) PD of any type.

Exclusion criteria

  • Angle of deviation less than 40 PD or more than 55 PD.
  • History of previous surgery.
  • Inconcomitant exotropia.
  • Incomitance in any gaze.
  • Associated vertical deviation(oblique dysfunction,A or V pattern).
  • Patients with neurological deficit.

Treatment and study plan

Surgery

Procedure

69 Patients with exotropia of (40-55) PD who are ≥ 5 years old. The 1st group 30 patients had two muscles surgery; bilateral lateral rectus recession.

The 2nd group 39 patients had three muscles surgery; bilateral lateral rectus recession and unilateral medial rectus tucking.
