Long term outcome of treated congenital/infantile esotropia: does early surgical binocular alignment restoring (subnormal) binocular vision guarantee stability?

PURPOSE: To answer this important outcome question. SUBJECTS AND METHODS: Retrospective review of a series of 60 qualified cases of congenital/infantile esotropia surgically binocularly "aligned" (= orthotropia +/- 8 PD) before 30 months of age and showing at one postoperative examination date at least some degree of (subnormal) binocular vision. Every patient was monitored over a very long postoperative followup period (mean 14.7 +/- 3.7 years). RESULTS: Early binocular alignment with some binocular cooperation does not guarantee a stable outcome. However, even though the final percentage of patients losing "alignment" is similar to that observed in other non-qualified series of "aligned" congenital/infantile esotropias, the loss of "alignment" takes place at a much later age, if some binocular cooperation was present at some time in the past. CONCLUSIONS: For congenital/infantile esotropia, achieving, at an early age, binocular "alignment" with some degree of binocular vision delays the loss of "alignment" and seems to reduce the chance of developing oblique muscle overactions.

Management of superior oblique overaction in A-pattern deviations.

Surgical management of overaction of the superior oblique muscle is discussed with reference to such conditions as A-pattern, Brown's syndrome, torsional torticollis, and homolateral inferior oblique or contralateral inferior rectus paresis. The authors perform weakening of the superior oblique from the temporal side of the superior rectus for slight or moderate overaction. They prefer posterior tenectomy for mild overaction and scleral disinsertion of the tendon in moderate overaction causing A-pattern of no more than 25 pd. With 25-30 pd. they perform translation-recession of the muscle by the nasal approach.

Posterior tenectomy of the superior oblique.

Modifications of the original technique for posterior tenectomy of the superior oblique are presented and the results obtained in 23 patients with a follow-up of two or more years are reported. The simplicity of the procedure and the lack of intra- and post-operative complications make it useful for surgical treatment of moderate A-pattern deviations.

Large bilateral medial rectus recession in early esotropia with bilateral limitation of abduction.

Large bilateral medial rectus recession was performed in a group of 85 patients presenting early large angle esotropia with bilateral limitation of abduction. The results obtained after three postoperative years demonstrated that the proposed method not only corrects the angle of deviation but significantly improves abduction and consequently torticollis. In spite of the large recession performed, both adduction and convergence were not significantly affected.

Duane's syndrome electro-oculography pattern.

Horizontal ocular saccadic positions were analyzed in 11 Type I and 3 Type II Duane's syndrome. In all 14 patients, a weakness of adduction was found. This finding, and extreme 40 degrees adduction, small corrective saccades were made probably due to co-contraction of the lateral rectus muscle, helping to make the diagnoses. The present paper would indicate that the Duane's syndrome has a pathognomonic eye position and movement tracing.
