Toxic optic neuropathy are a group of conditions manifested by reduction of visual functions secondary to damage to the anterior visual pathways from exposure to a toxin. The implicated toxin could be work-based, food or drink related, or iatrogenic medication....
Usher syndrome is the most common hereditary condition that affects both vision and hearing. It is an autosomal recessive condition characterised by retinitis pigmentosa (RP) and bilateral sensorineural hearing loss [1,2]. Usher syndrome is the cause of approximately 10% of...
With more than 2,000,000 people in the UK living with some degree of sight loss and over 300,000 registered as blind or partially sighted, it is important for anyone living with sight loss to know they’re not alone. At what...
The authors report the histopathological changes of retinal ganglion cells (RGCs), optic disc and optic nerve in rabbit with advanced retinitis pigmentosa (RP). RP was recreated in rabbits by using bacterial artificial chromosome transgenesis, with the purpose of increasing understanding...
Retinoblastoma is the most common eye cancer in childhood, with enucleation rarely being the only lifesaving surgical option, especially where evidence of extraocular spread is apparent. This study sought to survey a global pool of eye care professionals with regards...
Glaucoma is a common condition where increased ocular pressure can lead to death of retinal ganglion cells due to impaired drainage of fluid from the eye. One mechanism involved in glaucoma is remodelling of the extracellular matrix at the lamina...
The author presents a literature review searching the terms ‘pituitary ring sign’ and ‘sphenoid sinus mucosal thickening’ in the context of pituitary apoplexy from 1990 until the present day. These two findings are both magnetic resonance imaging (MRI) signs of...
Fungal keratitis (FK) is a blinding condition prevalent in agricultural areas of countries such as India and China. The fungus enters the cornea and induces an inflammatory response which leads to tissue damage. Neutrophils are the earliest infiltrating immune cells...
The authors report on a cross-sectional study evaluating postural control and history of falls in glaucoma patients. History of falls was obtained using the Falls Screening and Referral Algorithm. Postural stability was assessed using a force platform under four conditions:...
Acquired esotropia in cerebellar disease is well described but under-recognised. The pathogenesis of cerebellar esotropia is controversial. It is suggested it may be a result of disruption to central vestibular pathways. This article reports a case series of seven adults...
Patients aged over 50 presenting with isolated nerve palsies of the third (pupil sparring), fourth or sixth nerves, are often described as having microvascular extraocular palsies. This review looks critically at the evidence surrounding these microvascular non-arteritic extraocular palsies and...
