New data suggests that hundreds of ophthalmology patients are experiencing avoidable and irreversible harm to their vison by not being able to access NHS appointments. Over 70% of optometrists in the UK have also said they have seen a patient in the last six months who had experienced a delay to treatment of 12 months or more. Ophthalmology within the NHS is one of the biggest outpatient specialty and is experiencing severe pressure under patient need. So could a nationalised eye health strategy from Government be the answer? The Association of Optometrists and the Macular Society think so. We speak to Farah Topia, Optometrist and Clinical Advisor for the AOP and to the Macular Society's chief executive, Cathy Yelf. The CSUN Assistive Technology Conference in California concluded last week. It is the world's largest event dedicated to exploring new ways technology can assist people with disabilities. Dave Williams from the RNIB was in attendance and he tells us what kind of exciting new technologies are in development.
