Pathogenesis Thyroid eye disease (TED) is an auto-immune condition, in the initial phase there is lymphocytic infiltration and oedema of the extraocular muscles with deposition of glycosaminoglycans and hyaluronic acid and adipogenesis, which can lead to an increase in the...

Testing of binocular contrast sensitivity as an objective measure of severity in intermittent exotropia

The purpose of this study was to compare the binocular contrast sensitivity ratio (measured with the Vision CSV-100 vector chart) between 40 intermittent exotropia patients and 40 normal controls. The authors also evaluated the effect of intermittent exotropia compensation status...

The ‘art’ of refraction – designing a refraction course

Learning how to refract requires theoretical knowledge, practice and determination. Refraction is a notoriously challenging skill to acquire and the competing demands on junior ophthalmologists can often be restrictive of the development of this core skill. To consolidate theory learnt...

Under pressure: a tool to aid the
