purpose: to describe three cases of exotropic mobius syndrome and to report outcomes of the surgical intervention. case reports: three patients including two boys and one girl were referred to our strabismus clinic. all had masked faces and non-progressive congenital bilateral facial palsy and dry eye. other abnormalities included large angle exotropia and bilateral horizontal gaze palsy. surgi...

A 66-year-old female presented with exotropia and hypertropia of her left eye. She had a previous history of lateral rectus recession and medial rectus resection of her left eye 20 years prior to old oculomotor and trochlear nerve pareses. She was treated with a botulinum toxin injection in the inferior oblique and lateral rectus muscles of her affected eye. In this case, the patient’s exotropi...

PURPOSE To report the incidence and the factors of consecutive esotropia (ET) in patients with immediate postoperative overcorrection of at least 17 prism diopters (PD) after surgery for intermittent exotropia (X(T)). METHODS Four-hundred-five patients under the age of 18 were included in this study. They underwent bilateral lateral rectus recession (LROU-rec) or unilateral recession-resectio...

Objectives: Manifest strabismus in children is a major cause of suboptimum visual experience with attendant impact on their development. This study aims to determine the pattern manifest among attending Paediatric Ophthalmology clinic University Port Harcourt Teaching Hospital, Rivers State. Materials and method: One hundred twenty-five (125) children, aged 6 months 18 years were ...

In a quantitative genetic investigation of seven clinical tests, five pairs were significantly correlated: (1) cover test measures and corneal power, (2) corneal power and divergence recovery points, (3) convergence and divergence recovery points, (4) divergence break and recovery points, and (5) convergence break and recovery points. Common genes may account entirely for the gene influence on ...

BACKGROUND To compare the rate of exodrift after a second surgery for recurrent exotropia, in patients grouped to fast versus slow exodrift after their first surgery. To determine whether there is a correlation with surgical outcome, and to evaluate the factors associated with fast exodrift. METHODS Patients with recurrent intermittent exotropia, who underwent contralateral lateral rectus rec...

Recent studies have implicated exotropia as a risk factor for schizophrenia. We determined whether schizophrenia biomarkers have abnormal levels of expression in extraocular muscles from patients with strabismus and explored whether differences in gene expression between medial and lateral rectus muscles may explain the specific association of schizophrenia with exotropia but not esotropia.
