Optometry researchers funded to assess the impact of myopia interventions on vision and visual behaviour in children Research partnership will improve understanding of myopia management strategies in children Two-year collaboration between Aston University and industry Researchers at Aston University specialising in myopia or short sightedness are starting work on a project with industry partners to better understand how myopia management strategies affect children. The research team based in the College of Health and Life Sciences has secured a £500,000 grant to determine the impact of myopia management interventions on vision and visual behaviour in children, for example, looking at how their vision responds to an intervention such as spectacles when they view objects at different distances. The new grant builds upon the team’s portfolio of research in the field of myopia, where clinical studies are underway with children between the ages of six and 15 years old. The researchers are working on slowing the progression of myopia in children. The interventions under trial include low dose atropine eye drops, contact lenses and spectacle lenses. Myopia is an eye condition where distant objects appear blurry. It typically occurs in childhood and progresses through the teenage years. It can lead to eye disease in later life, as the eye grows longer with myopia, it causes stretching in parts of the eye. Myopia is becoming increasingly prevalent throughout the world and it has been predicted to affect approximately 50 per cent of the world's population by 2050, based on trending myopia prevalence figures. Myopia is an overlooked but leading cause of blindness, particularly among the working age population. The two-year programme of research is being led by an internationally recognised team of academics from the School of Optometry, including Professor Leon Davies, Professor Nicola Logan, Dr Amy Sheppard, and Professor James Wolffsohn. The research grant will also support the appointment of two clinical research optometrists. Professor Leon Davies, professor of optometry and physiological optics at Aston University and president of the College of Optometrists said: “As Aston University has an established, internationally recognised track record in myopia research, we are pleased to be able to continue our work in this area to further our understanding of myopia management strategies for the benefit of patients.” Professor Nicola Logan, professor of optometry and physiological optics, at Aston University added: “As an advocate for evidence-based advancements, this research collaboration will further our scientific understanding of myopia progression. The work will increase our knowledge and better facilitate translation to clinical practice to manage young children more actively with myopia.”

School of Optometry ophthalmic equipment will furnish three polyclinics – presented by Canon Medical for the duration of the Birmingham 2022 Commonwealth Games Aston University clinical and academic staff volunteers are part of a team running the clinics The polyclinics presented by Canon Medical are due to open to athletes on 22 July. Aston University optometrists and dispensing opticians from its School of Optometry have been preparing various pieces of ophthalmic equipment needed to furnish three eye health polyclinics presented by Canon Medical at the Birmingham 2022 Commonwealth Games. The polyclinics presented by Canon Medical will be hosted at the Birmingham 2022 villages at the University of Warwick & University of Birmingham. The equipment, which is on loan from the School of Optometry, includes slit lamps, ophthalmoscopes, visual field screeners and tonometers. It was loaded up on Saturday 16July and Monday 18 July and was then transported to the three sites in preparation for the opening of the service on 22 July. Athletes and the wider Birmingham 2022 community will be able to access emergency eye care at the clinics. Athletes who need emergency access to glasses and contact lenses will also be able to get them from the polyclinics. The service is being run by volunteers who have had role-specific training provided by the Games medical team. Aston University’s volunteers are academic and clinical staff from the School of Optometry. Leon Davies, professor of optometry & physiological optics at Aston University, has led the clinic set up and is also a polyclinic volunteer. He said: “It is an honour to support the Birmingham 2022 Commonwealth Games through loaning our ophthalmic equipment, and I am proud of my colleagues who have volunteered to help run the clinics. “We are excited to provide athletes’ eye care whilst they are here in Birmingham. We appreciate some may have travelled long distances so on arrival might need to seek advice regarding a range of eye health issues. This could include anything from dry eye (due to a long flight), seasonal problems affecting eye health, or an issue with their spectacles or contact lenses.” The polyclinics presented by Canon Medical will be open every day from 7am – 11pm from 22 July to the end of the Games on 10 August.

Virtual talks, charity fundraising and cross-university collaboration

Optometry Today  online

Optometry schools around the UK usually take it in turns to host BCOVS, and it was originally going to be held at Aston University this year. The decision to share the organisational role originated when Professor Leon Davies, head of Aston Optometry School, and I initially discussed moving the conference to a virtual platform. We thought it would be a great opportunity to allow input and positive contributions from a wider range of people, and because it’s a completely new venture for BCOVS, it seemed sensible to seek advice. The aim was to get a representative from every optometry school, but we’re still a few short so if you’re reading this and you don’t think your department has a representative yet, please get in touch.

BCLA CLEAR presbyopia: Mechanism and optics

Contact Lens and Anterior Eye

2024

With over a billion adults worldwide currently affected, presbyopia remains a ubiquitous, global problem. Despite over a century of study, the precise mechanism of ocular accommodation and presbyopia progression remains a topic of debate. Accordingly, this narrative review outlines the lenticular and extralenticular components of accommodation together with the impact of age on the accommodative apparatus, neural control of accommodation, models of accommodation, the impact of presbyopia on retinal image quality, and both historic and contemporary theories of presbyopia.

Utility of artificial intelligence-based large language models in ophthalmic care

Ophthalmic and Physiological Optics (OPO)

2024

Purpose
With the introduction of ChatGPT, artificial intelligence (AI)-based large language models (LLMs) are rapidly becoming popular within the scientific community. They use natural language processing to generate human-like responses to queries. However, the application of LLMs and comparison of the abilities among different LLMs with their human counterparts in ophthalmic care remain under-reported.

Effect of peripheral defocus on axial growth and modulation of refractive error in children with anisohyperopia

Ophthalmic and Physiological Optics

2023

Purpose
To establish whether axial growth and refractive error can be modulated in anisohyperopic children by imposing relative peripheral hyperopic defocus (RPHD) using multifocal soft contact lenses.

Methods
This study is a prospective, controlled paired-eye study with anisohyperopic children. Axial growth and refractive error were observed without intervention for the first 6 months of the 3-year trial with participants wearing single vision spectacles. Then, participants wore a centre-near, multifocal, soft contact lens (+2.00 D add) in their more hyperopic eye for 2 years, with a single vision contact lens worn in the fellow eye if required. The ‘centre-near’ portion of the contact lens in the more hyperopic eye corrected distance refractive error while the ‘distance’ portion imposed hyperopic defocus in the peripheral retina. Participants reverted to single vision spectacles for the final 6 months.
