Vision screening standards for fitness to drive
Most countries require that vision meets a pre-defined standard in order to be legally permitted to drive, but these standards vary widely. The primary method by which vision is assessed to determine suitability for driving is by measuring visual acuity...
A retrospective medical notes review in patients with poor vision due to NAION
Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...
Ocular manifestation of Marfan Syndrome
This repeated cross-sectional study collected data in 2003-2004 and 2014-2015 to investigate changes in ocular features in Marfan syndrome (MFS) fulfilling the Ghent-2 criteria. Ghent-2 is a set of criteria by which MFS are identified and includes aortic root aneurysm...
Development of testing protocols for high and low contrast visual acuity
Dysfunction of the afferent visual system, characterised by impairments in high-contrast visual acuity (HCVA) and low-contrast visual acuity (LCVA) have been demonstrated in some neurological conditions such as multiple sclerosis and Parkinson’s disease. HCVA and LCVA are also potential quantitative...
Online tool for converting finger counting acuity into Snellen equivalent
The authors describe an online tool which has the purpose of converting count finger measurements of visual acuity into Snellen equivalents. The purpose of this is to allow the re-interpretation of retrospectively collected data that provide visual acuity in this...
Who will benefit from cataract surgery?
The need for cataract surgery is expected to rise dramatically in the future due to the increasing proportion of elderly citizens and increasing demands for optimum visual function. The aim of this study was to provide an evidence-based recommendation for...
