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 ...

INTRODUCTION Pseudostrabismus is a common diagnosis in a busy pediatric ophthalmology practice. This purpose of this study was to determine the prevalence of true strabismus in patients previously diagnosed with pseudostrabismus, to determine risk factors, and to examine the sensory outcome. METHODS This is a retrospective review of patients diagnosed with pseudo-strabismus and with at least ...

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...

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...

PURPOSE To evaluate factors associated with the direction of horizontal deviation in the sensory strabismus of patients with unilateral organic amblyopia. METHODS The medical charts of 53 patients who had been diagnosed with sensory strabismus between 2000 and 2009 were reviewed retrospectively. The underlying ocular disease, time of onset and the duration of vision impairment, refractive err...
