No CPD Points

This edition of Advances in Eyecare focuses on a variety of issues associated with low vision and takes a closer look at the Medicines Use Review service offered by pharmacists.

Dark Adaptation: Dr Ian Murray discusses his research on dark adaptation in early stage AMD, exploring the implications of this research, and whether it has the ability to aid the earlier detection of the disease.

Depression & Low Vision: Dr Tom Margrain reviews the outcomes of his study, a recent collaboration between the charity Guide Dogs and Cardiff University, on the prevalence of depression in the visually impaired.

Comorbidities & Low Vision: Dr Helen Court discusses her cross-sectional analysis of the comorbidities of visual impairment.

Eccentric Viewing: Professor Chris Dickinson summarises her research on eccentric viewing and associated techniques, including steady eye strategy, in order to determine the usefulness of such visual training for patients.

Medicines Use Review: Bobby Sira, a Consultant Pharmacist, speaks about the importance and function of Medical Use Reviews in clinical practice.

Unit 4 - Eccentric Viewing (~20 mins)

Eccentric Viewing

Sight loss has an impact on every aspect of individuals’ lives. Where there is central vision loss from macular damage, techniques have been developed to help patients adapt to using their still healthy peripheral retina. Other techniques, such as steady eye strategy, help patients with field loss that affects normal visual scanning.

Anthony McGrail speaks to Professor Chris Dickinson to find out how useful such visual training can be.
