In other fields of medicine the extent of a patient’s understanding in areas of the disease and treatment has been shown to have both a direct and indi-rect eVect on subsequent concordance. The aims of this study were to determine the extent of parental non-concordance, to assess their level of understanding in key areas of amblyopia, occlusion therapy, critical period and prognosis, and to discover the parent’s own reasons for fail-

Preterm children are at increased risk from a number of cerebral lesions resulting in visual and oculomotor deficits. We have extended our investigation of monocular oculomotor control to examine the conjugacy of binocular saccades in children born preterm. Methods: We compared 8 preterm children (aged 9-10 years) with normal IQ (>85) who were free from major neurological deficit and 7 full term age matched controls. Subjects viewed a monitor binocularly from 57cm with their head stabilized. Eye movements were recorded using infrared oculography. Intra-saccadic disconjugacy and post-saccadic vergence drift 75ms and 150ms after the peak disconjugacy were measured. Results: The amplitude of saccade disconjugacy was larger for preterms (convergent: 1.6±0.9°; divergent: 1.9±0.9°; mean±sd) compared to full term controls (convergent: ...

Older people have poor vision and published evidence suggests that it is a risk factor for falls. Less than half of falls clinics assess vision as part of the multi-factorial assessment of older adults at risk of falls despite vision being an essential input for postural stability. The aim of our study was to investigate the relationship between all clinically assessed visual functions and falls amongst older adults in a prospective observational individually age-matched case control study. Methods Visual acuity (VA), contrast sensitivity (CS), depth perception, binocular vision and binocular visual field were measured using routinely used clinical methods in falls participants (N = 83) and non-falls participants (N = 83). Data were also collected on socio-demographic factors, general health, number of medications, health quality, fear of falling and physical activity. Logistic regre...
