During the last half of the 20th century, the field of strabismus did not undergo as many major advances as other areas of ophthalmology. In recent years, an increase in basic science research has fostered important advances in our understanding and treatment of disorders of binocular vision. This article identifies 4 important questions that need to be addressed by the pediatric ophthalmology ...

Strabismus may result from abnormal innervation, structure, or function of the extraocular muscles. Abnormalities of the orbital bones or masses within the orbit may also cause strabismus due to indirect effects on the extraocular muscles. This paper reviews some disorders of the orbit that are associated with strabismus, including craniofacial malformations, orbital masses, trauma, and anomalo...

PURPOSE To study the clinical signs, treatment and prognosis of strabismus after sub-Tenon's anesthesia for cataract surgery. METHODS Eight patients without previous strabismus developed incomitant diplopia immediately after cataract surgery; the left eye was affected in five patients and the right eye in three. Restrictive strabismus was diagnosed with the cover test, prisms, and active and ...

Dynamic vergence eye movements in response to step target displacements along the midline were measured by an infrared reflection technique in 11 patients having either intermittent strabismus, constants-strabismus amblyopia, or amblyopia without strabismus. We found the absence of normal disparity (fusional) vergence in all patients having strabismus and in some patients having amblyopia witho...

PURPOSE To compare binocularity in central and peripheral vision of people with early-onset strabismus and people with normal binocular vision. METHODS Ten subjects with early-onset strabismus, and nine subjects with normal binocular vision were tested. To assess binocularity, interocular transfer (IOT) of a rotary movement aftereffect (MAE) was measured. The MAE stimuli were either confined ...

This report investigates line-of-sight asymmetric disparity vergence in patients having either intermittent strabismus, constant strabismus with amblyopia, or amblyopia without strabismus. We find an absence of disparity vergence in all patients with strabismus and in some with amblyopia only. Accommodative vergence and saccades place the dominant eye on the targets moving in depth. These accom...

A fundamental difference exists, from the sensory viewpoint, between the cases of constant squint developing before the third year of life and all the other forms of oculomotor imbalance. The first group is the one considered in the literature as that of "strabismus with anomalous correspondence". Must we consider the "anomalous correspondence" of these subjects as a system of corresponding ret...

PURPOSE To determine whether satisfactory results of both eyelid surgery and strabismus surgery can be obtained when these procedures are performed in the same setting in selected patients. METHODS Nine patients (16 eyelids) who had undergone surgery in the same setting for eyelid malposition and strabismus of the horizontal rectus muscles, with or without concurrent vertical rectus muscle su...

Dr. Nelson has no financial or proprietary interest in the materials presented herein. doi: 10.3928/01913913-20120523-01 The incidence of perioperative inflammation after strabismus surgery is uncommon. Many of these cases may be related to when there is prolongation of the suture material dissolving, creating conjunctival injection around the suture. This phenomenon is more common in adult str...
