Summary

Evaluation of the results of surgical correction of V pattern intermittent exotropia without inferior oblique muscle overaction by either performing bilateral lateral rectus recession (BLR) alone or performing bilateral lateral rectus recession asssosiated with upward transposition of lateral rectus muscle insertion

Detailed description

Intermittent exotropia (IXT) is the most common type of strabismus which is a disorder of binocular eye movement control in which one eye intermittently moves outwards.Intermittent exotropia may be associated with difference in the horizontal deviation from the primary position to the upward or downward gaze giving A or V pattern In V-pattern intermittent exotropia (XT), there is an increase in the horizontal deviation as the eyes move from downgaze to upgaze. Non-surgical treatment includes correction of refractive error, orthoptics, overcorrecting minus lenses and prismotherapy. Surgical options includes unilateral medial rectus muscle resection combined with a lateral rectus muscle recession or bilateral lateral rectus recession as in basic type IXT OR bilateral lateral rectus muscle recession as in divergent excess type OR bilateral medial rectus muscle resection as in convergence insufficiency.

Conditions

• Surgical Correction
• V Pattern
• Intermittent Exotropia
• Inferior Oblique Muscle
• Overaction

Interventions

Type	Name	Description
PROCEDURE	Bilateral Lateral Rectus Recession (BLR Recession)	This procedure involved recession of both lateral rectus muscles to reduce large-angle exotropia.
PROCEDURE	Bilateral Lateral Rectus Recession with Upward Transposition	This procedure involved bilateral lateral rectus recession combined with upward transposition of the insertion to enhance ocular alignment in patients with large-angle exotropia.
