    54: Headaches – Causes and clinical management
    Nov 19 2025
    It’s thought that over half of the world’s population experience a headache disorder, and almost all of us have experienced the symptoms at some point in our lives. Headaches can be caused by many different factors — both visual and non-visual — and their severity can vary massively. When optometrists are examining patients, it’s not always clear how concerned to be or what to do next. After all, headaches could be a sign of an underlying health problem, from hypertension to brain tumours.

    In this episode, Michelle Hanratty is joined by Hilary Hodgson and Dr Nav Chana, who together advised a new six-part course about headaches available on the Docet website. Hilary, an optometrist, begins by explaining what to look out for in eye examinations. Dr Chana, a GP, goes on to discuss when to refer on patients and how primary care practitioners can work together to understand the causes of headaches in a timely manner.

  • 53: Periorbital Skin conditions – What’s an optometrist to do?

    53: Periorbital Skin conditions – What’s an optometrist to do?
    Oct 15 2025
    Skin conditions are very common in the UK; for example, up to 30% of children and 10% of adults suffer from eczema. Dermatological problems can cause great discomfort or they could be the sign of a more serious underlying health condition. If the eye area is affected by a skin condition, optometrists are in a good position to help patients early-on, especially as it can sometimes be difficult to access a GP or a dermatologist in a timely fashion.

    In this episode, Bryan Murphy, a Consultant Dermatologist at Cathedral Health in Belfast, tells Michelle Hanratty why it’s essential for optometrists to understand periocular conditions, from allergies and inflammation to skin lesions. Bryan also provides practical advice for optometrists on history-taking and referrals when patients present with skin problems.

    52: 52: Brain tumours, 2 – Red flags for referral
    Sep 17 2025
    As we heard in episode 51, around a third of people affected by brain tumours report a problem with their vision. That’s why optometrists are uniquely placed to catch suspicious signs early and refer patients into hospital for further checks.

    In the second of two episodes on brain tumours and neuro-ophthalmology, Michelle Hanratty speaks to Lorcan Butler, an optometrist and the Optical Engagement Manager at The Brain Tumour Charity. Lorcan explains the clinical signs to look out for, when to be suspicious and what best practice is for referring patients on.

    We also hear stories from brain tumour patient, Connor McCann (episode 51), idiopathic intracranial hypertension patient, Shannen Brodrick (episode 9); and communication tips from ophthalmologist, Dr Naz Raoof (episode 2).

  • 51: Brain tumours, Part 1 – A unique perspective

    51: Brain tumours, Part 1 – A unique perspective
    Jul 16 2025
    A brain tumour is an abnormal growth or mass of cells in or around the brain. They can be life-threatening and their incidence is increasing in the UK, as the population gets older. Around a third of people affected by a brain tumour report a problem with their vision. That’s why optometrists are uniquely placed to catch suspicious signs early and refer patients into hospital for further checks. You may well end up saving a life.

    In the first of two episodes on brain tumours and neuro-ophthalmology, Michelle Hanratty speaks to Connor McCann, an optometrist in Bristol who was incidentally diagnosed with a brain tumour in 2022. Connor explains what it’s like to live with — and treat — brain tumours. He also shares insights on how to communicate with and care for patients with more compassion and empathy.

    Read more about Connor’s story on his blog, called “Eye Am Connor”.

  • 50: Diabetic retinopathy – Dots and blots of significance

    50: Diabetic retinopathy – Dots and blots of significance
    Jun 25 2025
    Diabetic retinopathy is a leading cause of blindness among working age people worldwide. But thanks to the Diabetic Eye Screening Programme and an improved understanding of the impact of glycaemic control on diabetic retinopathy, there has been a significant reduction in the level of sight-loss in England and Wales. By catching the early signs of disease, eye care practitioners play a vital role in preventing the worst outcomes, such as proliferative retinopathy and diabetic macular oedema. Can this positive trend continue?

    In this episode, Michelle Hanratty speaks to Dr Rosalind (Rosie) Creer, a Lead Optometrist for Diabetes at Manchester Royal Eye Hospital. Rosie emphasised how blood sugar control is directly linked to retinopathy progression, how to differentiate between different types of lesions and why the recent changes that have been made to eye screening programmes could affect optometrists.

    Rosie also presented Docet’s recent webinar, called, “Joining the Dots (and Blots) of Diabetic Retinopathy” and answers some of the questions that optometrists left during that session.

    Find more information on the Diabetic Eye Screening Programme (and grading criteria) in England, Wales and Northern Ireland on the nations’ public health websites.

  • 49: Enhanced Optometric Services – Here, there and nearly everywhere

    49: Enhanced Optometric Services – Here, there and nearly everywhere
    May 21 2025
    Since COVID-19, a greater number of enhanced optometric services have been rolled out across much of the UK. These pathways have been proven to reduce the burden on secondary care, reduce patient waiting times and have saved the NHS millions of pounds. As a result, Integrated Care Boards (ICBs) have commissioned optometric services far beyond CUES, MECS and pre- and post- operative cataracts. For example, in some areas, optometrists are now providing paediatric and glaucoma services in the community. What impact are these enhanced pathways having?

    In this episode, Michelle Hanratty speaks to Dharmesh Patel, the CEO of Primary Eyecare Services – the largest provider of enhanced optometric care in England. Plus, Michelle asks Hayley Moore, an optometrist in Essex, about her experience of delivering enhanced paediatric and glaucoma services. Dharmesh and Hayley also provide their top tips for optometrists who want to upskill and get involved.

  • 48: PACS – Management of primary angle closure suspects

    48: PACS – Management of primary angle closure suspects
    Apr 23 2025
    Primary angle closure disease is more common in the UK than was initially thought and it is important for optometrists to understand the condition’s stages of progression; from primary angle closure suspect (PACS), to primary angle closure (PAC) and primary angle closure glaucoma (PACG). PACG is the stage we want to avoid, where structural damage to the optic nerve and loss of visual function have occurred because of the occluded drainage angle. PACG is far more visually destructive than primary open angle glaucoma, but if we detect the signs of primary angle closure disease early, preventative measures can be implemented, such as laser peripheral iridotomy or clear lens extraction.

    In this episode, Michelle Hanratty speaks to Nishani Amerasinghe, a consultant ophthalmic surgeon in the south of England, who presented Docet’s recent webinar, called “PAC, PACS, and PACS+ in Focus: A guide for optometrists”.

  • 47: Chronic Stress – The brain-body connection

    47: Chronic Stress – The brain-body connection
    Mar 20 2025
    Stress and burnout, which we explored in the last episode of Sound Optometry, is far from uncommon in optometrists. In this episode, Michelle Hanratty uncovers the severe implications that chronic stress can have on the health of optometrists in the future. How can we reverse its damage?

    Michelle is joined by Professor Anna Whittaker, a health psychologist at the University of Stirling, who highlights the role of cortisol in stress responses and its long-term effects on mood, weight, sleep and the immune system. Professor Vanja Duric, a neuroscientist at Des Moines University in Iowa, also elaborates on how chronic stress can affect the brain in an unexpected number of ways.

    Listen to our previous episode on how to address the root causes of stress in the workplace (episode 46).
