OCT angiography metrics in children

This prospective study aimed to quantify the vessel density of both the macular and optic nerve and foveal avascular zone (FAZ) values in 92 normal eyes of 92 children (42 boys, 50 girls) aged 13.4 ±2.65 years (seven to 18)....

Comparison of two visual acuity test versions for different distances in a paediatric population

The authors present the findings of a study which aimed to determine whether using 2 metre and 4 metre retro-illuminated ETDRS charts are comparable in children. Order of testing was standardised (right eye, left eye, binocular), however different charts were...

In conversation with Dr Harold Quigley (2018)

Dr Quigley visited the Eye News stand at the 2018 Royal College of Ophthalmologists Annual Congress to tell us about his Optic UK lecture on the topic of '21st century glaucoma treatment', which covered how we should define, treat and...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Effect of intravenous mannitol in post vitrectomised eyes

The purpose of the study was to evaluate the effect of intravenous mannitol 20% on intraocular pressure in vitrectomised silicone-oil filled eyes. A prospective analysis of consecutive patients was undertaken with their fellow eyes taken as controls. Thirty-one patients were...

Visual field changes in thyroid eye disease (TED)

This study is a retrospective non- comparative review of visual field (VF) tests in patients with compressive optic neuropathy from thyroid eye disease (TED-CON). Ninety-six visual fields in 68 patients were included in the study and a two-step analysis of...

DIY IOP – does it work?

Measuring intraocular pressure (IOP) plays a major role in glaucoma care as IOP is a parameter, along with visual field progression and optic disc cupping used to assess treatment effect. While Goldmann tonometry (GAT) is the gold standard, it only...

Resolution of idiopathic intracranial hypertension (IIH): case series

The authors report the findings from 14 patients following treatment for idiopathic intracranial hypertension (IIH). All 14 patients experienced an immediate and sustained resolution of the IIH in the setting of prolonged cerebrospinal fluid (CSF) drainage at a rate greater...

Bitemporal hemianopsia as a result of ethambutol toxicity

The authors present six cases of visual loss in patients treated with ethambutol for mycobacterium avium complex, including four patients with bitemporal hemianopsia. Two additional patients were undergoing glaucoma monitoring and developed visual field defects with ethambutol treatment, which recovered...

A case report of visual loss as a consequence of coeliac disease

The authors present a case of permanent visual loss secondary to occipital lobe calcification in coeliac disease, the first reported such case. The 58-year-old man had been diagnosed with coeliac disease 20 years prior to his visual investigations and had...

Associations of esotropia with shunts

This study explored the characteristics and outcomes of children with esotropia and ventriculo-peritoneal (VP) shunt placement due to hydrocephalus. The authors conducted a retrospective study of 16 patients (nine female, seven male) aged three months to 5.6 years (mean 17...
