Amblyopia was detected in 15 of 55 children with unilateral congenital ptosis. Anisometropia was the main cause of the amblyopia in 10 cases, and strabismus alone was the cause in 2 cases. In three cases amblyopia developed after ptosis surgery.
An 11-year-old Quarterhorse mare developed a paranasal sinus osteoma that extended into the right orbit and led to ipsilateral exophthalmia. Although the tumor was radiographically evident in the paranasal sinuses, ultrasonography was used to demonstrate extension of the tumor into the retrobulbar space, and endoscopy was used to identify its extension into… (More)
Herpes simplex keratitis can cause severe loss of vision in children. The findings in five children show that amblyopia is caused by stimulus deprivation and/or anisometropia. Early medical treatment, occlusion therapy, and frequent refractions are crucial for a good visual prognosis.
Between July 1984 and March 1985, 51 injections of type A botulinum toxin were given to 39 patients aged 11 to 81 years with various types of strabismus, including paralytic strabismus, sensory exotropia, consecutive and residual postsurgical deviations and partially accommodative esotropia. All deviations were documented by orthoptic assessment and… (More)
A study was done of 22 children in whom exotropia developed following correction of hyperopia because of accommodative esotropia that had not been corrected surgically. The early onset of esotropia and high degree of hyperopia seemed to predispose to the spontaneous development of exotropia. Reduction of the hyperopia by 50% to 60% resulted in satisfactory… (More)
The results of conventional strabismus surgery are always somewhat uncertain, despite the most careful preoperative assessment. Yet it is important to achieve good alignment in patients with fusion potential who have intermittent exotropia, extraocular muscle paresis or a restrictive syndrome. Planning surgery for patients with thyroid myopathy and planning… (More)
