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...

RetCam use in differential diagnosis for retinoblastoma

The authors aimed to evaluate RetCam fundus photography and fluorescein angiography (FA) findings in pseudo retinoblastoma. This was a retrospective review of 36 eyes of 28 patients (of which six were female) with 22 bilateral cases. Mean age at presentation...

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...

Eye disorders occurring in congenital CMV

The aim of this study was to examine the relationship between congenital cytomegalovirus (CMV) infection and ophthalmological disorders that occur in children and record the frequency and type of eye disorders that occur from the infection. Of 449 potential studies,...

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...

Implantation of diffractive trifocal intraocular lens

This study reports on 60 eyes of 120 patients who underwent routine cataract surgery followed by implantation of the trifocal IOL model Lisa tri-839MP. This is a diffractive trifocal preloaded IOL with no interruption at the haptic-optic junction, 360 degrees...

Association between neuro-ophthalmology signs and chronic ataxia in children

Neuro-ophthalmological signs (N-OS) occur commonly in children with chronic ataxia. This study describes the N-OS and their frequencies, in general and by specific disease aetiology in paediatric patients with chronic ataxia. In total, 184 patients under the age of 17...

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...

Comparison between findings in ‘active’ or ‘healed’ giant cell arteritis

Giant cell arteritis (GCA) is the most common systemic vasculitis in older people and can cause devastating sight loss if untreated. Temporal artery biopsy is often relied upon for diagnosis by ophthalmologists, with a positive biopsy result indicating whether the...

Autologous scleral button for anterior defect in evisceration surgery

This is a small case series of five patients who have had evisceration surgery using a new technique. The anterior defect created when removing the corneal button has been closed by taking an autologous posterior scleral graft inferomedial to the...
