Fusion vergence measures

The purpose of this study was to compare fusional vergence measurements between orthophoria, esophoria and exophoria and determine the strength of correlation between fusional vergence and angle of deviation. This was a cross-section study of 530 children aged six to...

Surgical management and review of congenital inferior rectus dysgenesis

Three cases are presented of congenital inferior rectus (IR) dysgenesis causing hypertropia. Case 1 was a two-year-old female with intermittent vertical strabismus of 20PD and -2 limitation on depression, worse in abduction. MRI imaging showed a hypoplastic IR. Following surgery,...

Strabismus outcomes after retinal detachment surgery

A retrospective study reviewed the motor outcomes of strabismus surgery in a cohort of 18 patients who had all previously undergone a scleral buckling procedure to treat retinal detachment. The mean age at strabismus surgery was 48 years (14-67) and...

Angle of deviation measurements in seated and supine positions

The objectives of this study were to compare ocular deviation between the seated and decubitus positions in the operating room and assess the outcomes at one day, one month and three months postoperatively. This prospective study included 30 cases; two...

Mental health issues linked with strabismus

The purpose of this study was to determine if adults with non-paralytic forms of strabismus are at elevated risk for developing mental illness. This was a population-based case-controlled study of 297 adults with new onset non-paralytic strabismus; 42.4% were male....

Surgery for unilateral superior oblique palsy

This study evaluates the amount of effectiveness of inferior oblique myectomy in primary position, lateral gaze and head tilt, and the effect on improving extent of abnormal head posture. The study included 39 patients; 22 male, 25 left-sided palsy and...

Surgical technique for small-angle hypertropia

In order to treat small-angle hypertropia of <5PF associated with mild / moderate upshoot in adduction, an option is to suture the inferior oblique (IO) belly to the sclera following its natural muscle direction or with anterior transposition. This study...

Masked bilateral SO palsy

This study examined the occurrence of masked bilateral superior oblique (SO) palsy with contralateral inferior oblique (IO) over action requiring further surgical intervention in children undergoing unilateral IO weakening surgery for presumed unilateral SO palsy. This retrospective study included 50...

Diagnosis and management of IV cranial nerve palsy

Aetiology: Trochlear nerve palsy can be divided into acute or congenital. Congenital trochlear nerve palsy is usually noted in childhood with development of abnormal head posture. Various pathologies can lead to acute IV nerve palsy, most commonly trauma. Other causes...

Choroidal thickness in strabismus and amblyopia

The authors examined the effect of exotropia, esotropia, anisometropic amblyopia and hypermetropia on choroidal thickness in a prospective cross section study. The study included 100 patients and 20 controls with a mean age of 8.5±2.9 years; 61 female and 59...

Greater accuracy of cycloplegic refraction

The authors conducted this study on 5320 pre-school (four to six-year-old) and 6475 school (seven to ten years) children to compare the results of final glasses prescription based on cycloplegic refraction with atropine to those of non-cycloplegic refraction. For younger...

Ametropic amblyopia and stereopsis

This study aimed to evaluate the correlations between ametropic amblyopia (hypermetropic – 110, myopic – 30, and astigmatic – 65) and stereopsis in 205 children – mean age of 5.2 years ±1.8. For near stereopsis, significant results were found for...
