Determinents of ocular alignment at 6 month after intermittent exotropia surgery

Relationship between motor alignment at postoperative day 1 and at year 1 after symmetric and asymmetric surgery in intermittent exotropia.

PURPOSE To evaluate the relationship between the motor alignment at postoperative day 1 and at year 1 following bilateral lateral rectus recession (BLR, symmetric surgery) and unilateral lateral rectus recession-medial rectus resection (R&R, asymmetric surgery) for the treatment of intermittent exotropia, X(T). METHODS Forty-six patients with basic or pseudo-divergence excess type of X(T) und...

Astigmatic Changes after Horizontal Rectus Muscle Surgery in Intermittent Exotropia

PURPOSE To evaluate the changes of refractive astigmatism after horizontal rectus muscle surgery in intermittent exotropic children. METHODS Sixty-nine exotropic patients were retrospectively reviewed. Of those, 35 patients received unilateral lateral rectus recession (BLR group, 35 eyes) and 34 patients received unilateral lateral rectus recession and medial rectus resection (R&R group, 34 e...

Consecutive esotropia following surgery for intermittent exotropia.

Visual suppression in intermittent exotropia during binocular alignment.

PURPOSE To investigate the cortical mechanisms that prevent diplopia in intermittent exotropia (X(T)) during binocular alignment (orthotropia). METHODS The authors studied 12 X(T) patients aged 5 to 22 years. Seventy-five percent had functional stereo vision with stereoacuity similar to that of 12 age-matched controls (0.2-3.7 min arc). Identical face images were presented to the two eyes for...

Improvement in distance stereoacuity following surgery for intermittent exotropia.

PURPOSE To evaluate whether distance stereoacuity improves following surgery for intermittent exotropia using the Frisby Davis Distance (FD2) and Distance Randot stereotests. METHODS Eighteen patients (median age, 24 years; range, 5 to 68 years) with intermittent exotropia were prospectively enrolled. Stereoacuity was measured pre- and 6 weeks postoperatively using the FD2 and Frisby near tes...
