Single muscle surgery for hypertropia

The authors undertook partial tenotomies combined with graded marginal recession of single vertical rectus muscles to treat small angle hypertropia in four adults with fusion potential. They report dose response, surgical technique and outcomes. Dose response closely matched the theoretical...

Reliability of kinetic perimetry in children and young adults

This study reports on normative visual field area, feasibility and repeatability of testing for a large sample size of healthy children and young adults, using Octopus semi-automated kinetic perimetry. Sample included 221 healthy volunteers aged 5-22 years. The study was...

Retrospective review of visual outcomes in Idiopathic intracranial hypertension (IIH)

Idiopathic intracranial hypertension (IIH) is a clinical syndrome characterised by headache and papilloedema that can lead to significant visual morbidity. IIH is diagnosed by the modified Dandy criteria, which include normal neuroimaging and cerebrospinal fluid (CSF) composition, high CSF opening...

Viral uveitis

This review covers viral causes of anterior uveitis. A viral aetiology should be suspected when anterior uveitis is accompanied by ocular hypertension, diffuse stellate keratic precipitates or the presence of iris atrophy. Most common viruses associated are herpes simplex, varicella-zoster...

Treatment of vertical diplopia in the reading position

This paper describes the use of slab-off prisms for the treatment of vertical diplopia in the reading position. The following data were collected: main symptom complaint, visual acuity, refractive error, binocular vision including sensory fusion and stereoacuity, alternating cover test...

Principles of management

Whatever section of pathology is to blame and wherever it strikes, the aim of treatment is always the same. Find the cause if you can. Establish the effects of the cause. Halt the pathological process if you can. Reverse its...

Brn3b neuroprotective effect in rat glaucoma model

An adeno-associated virus-directed overexpression of the Brn3b protein in hypothesised to confer neuroprotective effects in this paper. This is ultimately tested in a well-accepted rat glaucoma model (Morrison’s model: saline injection into episcleral veins of rat eyes with a force...

Vertical disparity effects on horizontal fusion

This study was designed to investigate the effect of induced vertical disparity by prisms on horizontal fusional reserves at near distance. One hundred and seventy students were recruited and vertical disparity was induced by small vertical prisms of 0.5 and...

Comparison of visual fields between migraine and tension type headaches

The aim of the study was to compare the clinical features and visual fields of patients with migraine without aura and tension type headache. Visual fields were assessed whilst the patients were having an attack of pain and tested using...

International orthoptics for stroke

The purpose of this study was to consider the practice of orthoptists internationally in care provision for post stroke visual impairment through an international survey. An online survey of 30 questions was circulated via the International Orthoptic Association and completed...

Functional visual field loss using automated static perimetry

Functional visual field loss is traditionally assessed by kinetic perimetry, typically producing spiralling isopters. This study looked at the spatial distributions of functional field deficits using automated static perimetry. A retrospective review of automated perimetry records was conducted using a...
