Blinking and driving

Spontaneous blinking is dependent on cognitive processes and is regulated by a central pacemaker that is highly sensitive to the attention demands and cognitive workload of the visual task in hand. There is evidence of a variability in the frequency...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Principles of contact lens fitting in keratoconus

Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

Toxic nutritional optic neuropathy (TON)

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....

Progressive myelination of the retinal nerve fibre layer: Acquired or incidental?

*Co-first authors.Myelinated retinal nerve fibres are retinal nerve fibres encased by a myelin sheath, located anterior to the lamina cribrosa [1]. First described by Virchow in 1856, a myelinated retinal nerve fibre layer (RNFL) appears as a whitish, feathery patch...

My Top Five: Digital ophthalmology revision resources for medical students

Ophthalmology is a broad and exciting field to study but encountering the vast number of topics it contains for the first time in medical school can be a daunting prospect. Building a solid foundation of knowledge in the subject is...

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...

Paraproteinaemia: a patient with atypical corneal findings

A Bence Jones protein is a monoclonal globulin protein or immunoglobulin light chain found in the urine, with a molecular weight of 22-24 kDa [1]. Detection of Bence Jones protein may be suggestive of multiple myeloma or Waldenström’s macroglobulinemia. Multiple...

Lacrimal gland carcinoma

This is a major review of the management of lacrimal gland carcinoma, focusing mainly on adenoid cystic carcinoma. Relevant literature published in English since 1970 was included amounting to some 40 articles after filtering. Overall mortality for all lacrimal gland...

Acetylcholine receptor antibodies in the diagnosis of ocular myasthenia gravis at the Manchester Royal Eye Hospital

Myasthenia gravis (MG) is the commonest autoimmune condition to affect the neuromuscular junction. In the UK, its prevalence is 15 per 10,000 [1,2] and recent studies have shown that rates are steadily increasing [3,4]. Aims of this audit The aim...

Vital dyes in ophthalmology

This comprehensive review gives an excellent summary of the uses and properties of the different dyes available to aid better visualisation and diagnoses in ophthalmology. The authors clearly display the pharmacological properties, molecular details, osmolarity and indications in clinical ophthalmology...
