Occult Duane syndrome: co-contraction revealed following strabismus surgery.

Three patients presented in infancy with large angle esotropia and limited abduction. Narrowing of the lid fissures with globe retraction on horizontal gaze became apparent only after recession of the medial recti. Abduction remained limited. Two of the three exhibited dissociated vertical deviations, and seemed to have both congenital esotropia and Duane syndrome. The third had an unusual pattern of apparent co-contraction in which the eye attempting abduction actually adducted. Although rare, Duane syndrome may occur in children with large angle esotropia, and its presence may not be revealed until after strabismus surgery.

Synthetic polypeptide sleeve for strabismus surgery.

A synthetic polypentapeptide sleeve was placed around the superior rectus muscle of five New Zealand white rabbits in hopes of preventing postoperative fibrous scarring. Two forms of the polypentapeptide were used. No significant inflammation or scarring occurred with either form of the polypentapeptide when compared to controls. One form elicited a fibrous membrane surrounding the sleeve within 2 weeks. The other elicited no such reaction after 2 months. The latter form of the polypentapeptide may be useful in preventing scarring following strabismus surgery.

A cluster of patients with inferior rectus restriction following local anesthesia for cataract surgery.

During a 5-month period, four patients developed contracture of the inferior rectus muscle following local anesthesia for cataract surgery in the practice of one ophthalmologist. Two anesthesiologists administered retrobulbar anesthesia. All patients had persistent vertical diplopia caused by a large hypotropia of the operated eye. Forced duction testing revealed marked restriction to elevation of the eye. In two patients, MRI demonstrated segmental thickening of the inferior rectus muscle, just posterior to the globe. All patients had normal thyroid function tests. No patient had a previous history of strabismus. Three of the four have had strabismus surgery consisting of recession of the markedly restricted inferior rectus muscle on an adjustable suture. These three patients have regained fusion and are now asymptomatic.

Topical treatment of periocular capillary hemangioma.

Five patients with vision-threatening periocular capillary hemangiomas were treated with topical clobetasol propionate cream. Two received steroid eye drops. All experienced a decrease in the size of their hemangioma. Topical treatment of periocular capillary hemangioma appears to be well tolerated and, in selected cases, may eliminate the need for intralesional injection of corticosteroids.

Augmenting surgery for sensory esotropia with near/distance disparity with a medial rectus posterior fixation suture.

Ten esotropic patients with near/distance disparity and diminished vision in one eye had monocular horizontal strabismus surgery combined with a posterior fixation suture placed on the medial rectus. Before surgery, all patients were at least 20 prism diopters (delta) more esotropic at near than at distance fixation. The disparity in the near/distance deviation was reduced by 18 delta.
