Differential diagnosis of inflammatory optic neuritis

The authors present the differential diagnosis of inflammatory optic neuritis (ON) to include multiple sclerosis, infectious optic neuritis, systemic disease and neuromyelitis optica (NMO). The features of ON for the varying aetiologies are detailed including incidence and overlap. In acute...

SEE Summit on the Environment

@19.00 - 20.30 GMT This event, which is supported by the Association of Optometrists (AOP), the Association of British Dispensing Opticians (ABDO), the British Contact Lens Association (BCLA), the College of Optometrists, the General Optical Council (GOC) and the Optical Suppliers Association (OSA), aims to bring together the industry to increase awareness of – and engagement with – Social, Ethical and Environmental (SEE) issues.

A case report of Horner syndrome with neuromyelitis optica

This case report details a patient diagnosed with neuromyelitis optica (NMO) with an associated left Horner syndrome. The female patient presented with neck pain and right hemibody decreased pain and temperature sensation. She then went on to develop left ptosis...

A missed intraocular telescope – an opportunity to re-focus the evidence

Intraocular telescopes allow magnification of the image so that it would be projected into a larger area of the macula, this makes the central defect caused by dry age-related macular degeneration (AMD) smaller. The most common approach is a Galilean...

Validity of coding in neuro-ophthalmology within large administrative datasets

A systematic review of validation studies of the International Classification of Disease (ICD) coding system, ICD-9 and ICD-10 is presented by the authors. Three searches were conducted based on three concepts, firstly health administration claims and ICD codes, secondly diagnostic...

Density of cataract and its influence on retinal nerve fibre layer thickness

The aim of this study was to further define and model the influence of cataract on spectral domain optical coherence tomography (SDOCT) image quality and retinal nerve fibre layer (RNFL) thickness measurements. OCT quality is influenced by opacities in the...

Last-Minute Optics, Second Edition

For those who shudder at the thought of clinical optics, this is the book for you. Dr Hunter’s second edition of Last-Minute Optics is a resource for more than just last-minute cramming, despite its title. It provides a real-life perspective...

The Preston Rule

The selection, specification and fitting of a spectacle frame necessitates the recording of certain measurements particular to the frame. These measurements are also essential when it is required to manufacture a handmade spectacle frame. Instruments designed to accomplish this task...

Anisometropia following cataract surgery and its non-surgical treatment

The desired result of cataract surgery is improved visual acuity without the use of spectacles. In practice most patients following initial cataract extraction are likely to be symptomatic of anisometropia giving rise to prismatic effects (anisophoria) and unequal retinal image...

The Ophthalmic Antiques International Collectors' Club AGM

By John Dixon Salt, Chairman, OAICC. The OAICC was formed in 1982 by a small group of opticians interested in optical antiques. From the initial dozen members it has grown into a truly international club of enthusiasts with about half...

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

Retinal structural features of CMV retinitis

Confocal adaptive optics (AO) technology has enabled cellular level retinal imaging, including imaging of photoreceptors and blood flow. Adaptive optics scanning laser ophthalmoscopy (AOSLO) is a technology that provides high resolution and high contrast retinal images by correcting ocular aberrations....
