BACKGROUND There are few long-term outcome reports of unilateral lateral rectus (LR) recession for exotropia including a large number of subjects. Previous reports on unilateral LR recession commonly show extremely low rates of initial overcorrection and large exodrifts after surgery suggesting that the surgical dose may be increased. However, little is known of the long-term outcome of a large...

PURPOSE To characterize eye movements made by patients with intermittent exotropia when fusion loss occurs spontaneously and to compare them with those induced by covering 1 eye and with strategies used to recover fusion. DESIGN Prospective study of a patient cohort referred to our laboratory. PARTICIPANTS Thirteen patients with typical findings of intermittent exotropia who experienced fre...

Intermittent exotropia (IXT) is the most common form of childhood exotropia 2 with an incidence of 32.1 per 100,000 in children under 19 years of age. The strabismus is characterized by an exodeviation of one eye that is interspersed with periods of ocular alignment. Reliable measurement of the deviation is often hindered by the variable nature of the strabismus, and without careful observation...

BACKGROUND Little is known about the aetiological factors underlying strabismus. We undertook a large cohort study to investigate perinatal risk factors for strabismus, overall and by subtype. METHODS Orthoptists reviewed ophthalmological records for Danish National Birth Cohort (DNBC) children examined for strabismus in hospital ophthalmology departments or by ophthalmologists in private pra...

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...

PURPOSE To evaluate the surgical results of asymmetric bilateral lateral rectus recession in exotropic Duane retraction syndrome with abnormal face turn toward the opposite side according to secondary deviation measurements. METHODS Retrospective chart review. RESULTS Seven cases of unilateral exotropic Duane retraction syndrome were reviewed. All cases had globe retraction on adduction and...

Sixteen patients with large angle infantile esotropia with deviations of 80-90 prism dioptres were operated at the age of about 2 years. All patients underwent 8 mm bilateral medial rectus recessions. At the last follow up examination, 6 to 48 months postoperatively (average 16.3 months), successful horizontal alignment was achieved in 12 patients (75%). Four patients (25%) were undercorrected....
