Sarcoid uveitis and its systemic associations

This retrospective cross-sectional study examined systemic associations of sarcoid uveitis and association with uveitis clinical phenotype and ethnicity. Three hundred and sixty-two subjects with either definite or presumed sarcoid uveitis were identified and included in the study. Any subject with...

Is intracranial pressure affected by the valsalva manoeuvres and exercise?

Idiopathic intracranial hypertension (IIH) is characterised by elevated intracranial pressure (ICP), which leads to optic nerve head swelling and a risk of visual loss. The impact of straining and exercise on ICP regulation is poorly understood yet clinically relevant to...

Named in tribute to Altomed’s Northeast roots, Geordie is a striking black German Shepherd, confident, clever, and full of character. His unique breed makes him extra special within the Guide Dogs community. Geordie follows in the pawprints of Altomed’s first...

Intermittent exotropia and refractive change in children

The authors present a retrospective case review with the aim of examining the relationship between refractive change and intermittent exotropia (IXT). The medical records of patients were reviewed for those aged 18 years old and younger diagnosed with IXT with...

Intermittent exotropia with a positive Bielchowsky head-tilt test

This is a retrospective study from Korea, of 118 patients’ charts with intermittent exotropia (IXT) and divided into two groups; 50 patients showed positive Bielchowsky head tilt test (BHTT) and 68 with negative BHTT. Significant differences (p<0.05) in the parameters...

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...

A pattern surgery

The authors describe the efficacy and safety of superior oblique (SO) hang-back recession with A pattern strabismus and SO overaction. A pattern was defined as a difference of >10PD from elevation to depression. SO overaction was graded as +1 to...

Prediction of recurrence in exotropia

This study compares the long-term motor and sensory outcomes between constant and intermittent exotropia in infancy and investigated whether constancy can be used as a reliable factor for predicting surgical outcomes. Sixty-seven patients were reviewed – 37 constant and 30...

Supranuclear palsy

This paper reports the results of surgery for supranuclear monocular elevation deficiency. Contralateral superior rectus maximal recession was undertaken without interfering with the superior oblique tendon position, transection of the superior oblique to the superior rectus frenulum and directly suturing...

Automated Bruckner device accuracy

The authors developed a Bruckner device, examined volunteers and determined the relation between the luminance of the red fundus reflex and eye rotation. Eye rotation was varied continuously both horizontally (-7 to 8 degrees) and vertically (five degree total range)...

N-T asymmetry in tracking eye movements

The current study aimed to quantify and compare the visual tracking responses of two sensory induced strabismic juvenile monkeys during monocular smooth pursuit, ocular following response and optokinetic nystagmus (OKN). Monkey 1 had esotropia and monkey 2 had exotropia. Both...

Surgical outcomes in third nerve palsy

The authors of this article explore the factors associated with successful surgical outcomes in third nerve palsy, which is known to be difficult to treat. A number of case notes were reviewed for patients who underwent surgery or botulinum toxin...
