Contrast sensitivity in myopic eyes

A classification system has been proposed for myopic maculopathy: grade 0 (no myopic retinal lesions), grade 1 (tessellated fundus), grade 2 (diffuse chorioretinal atrophy (CRA)), grade 3 (patchy CRA), and grade 4 (macular atrophy). Tessellated fundus is defined as the...

Saccades and contrast sensitivity in retinoblastoma survivors

The authors report a cross-sectional study, which recruited children aged 5 to 18 years old who completed treatment completion for retinoblastoma more than six months ago. Exclusion criteria included bilateral enucleation and pre-existing conditions associated with cognitive impairment. A total...

Contrast sensitivity after laser corneal surgery

This study group compared contrast sensitivity among participants undergoing wavefront-guided or wavefront-optimised photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK) for the treatment of myopia or myopic astigmatism 12 months after surgery. This was a prospective, randomised clinical trial,...

A comparison of colour vision tests in the presence of contrast sensitivity loss

This study analyses the effect of contrast sensitivity (CS) loss on colour vision (CV) testing, using a variety of colour vision tests. The authors used a computer model for CS loss to determine its effect on CV testing scores for...

Contrast sensitivity comparisons for Pelli Robson, Hiding Heidi and Double Happy tests

The authors aimed to compare contrast thresholds and measure agreement across current paediatric assessment of contrast sensitivity with Hiding Heidi and Double Happy contrast sensitivity tests vs. the gold-standard Pelli Robson chart. Reduced contrast levels were similar under different light...

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...

Effect of single intravitreal injection of bevacizumab on contrast sensitivity in patients with central retinal vein occlusion

Central retinal vein occlusion is the second most common retinal vascular disorder after diabetic retinopathy. There are many studies reporting the efficacy of intravitreal anti-VEGF injections for macular oedema secondary to retinal vein occlusions. This paper looks at the contrast...
