  • 57: Adult Diplopia – Double the trouble?
    Mar 19 2026

    When we think about binocular vision (BV), we typically focus on the paediatric cohort. But there are hundreds of thousands of adults across the UK who have developed BV issues later in life, including double vision. This can be a clinical challenge that not every optometrist is confident in managing. Many of these patients struggle with their daily activities. Some people lose hope that their vision can be restored.

    In this episode, consultant ophthalmologist Nadeem Ali tells Michelle Hanratty that there are options available for adults with double vision, not just prism correction in spectacles. By pinpointing the likely cause of BV issues, optometrists can identify patients who might benefit from treatment and refer them on to secondary care. Nadeem provides insights from more than two decades of experience performing squint surgery, both within the NHS and at his private London Squint Clinic. Squint surgery has improved the quality of life for many patients; such as Pauline Brand, who also tells her story.

  • 56: Cataract Surgery – Meeting challenges and reducing risk
    Feb 25 2026

    More than 1,500 cataract operations are carried out every day across the UK, making it one of the most common types of elective surgery undertaken by the NHS. But there are significant challenges facing cataract service delivery, with many patients — especially those with co-morbidities — struggling to access timely care. Could innovations help?

    In this episode, Michelle Hanratty asks Dr David Lockington, a consultant ophthalmologist and the President of the UK and Ireland Society of Cataract and Refractive Surgeons, about how cataract surgery has evolved in recent years. They discuss how appropriate referral and effective management by community optometrists can help to mitigate risks in patients. David also explains how the use of advanced lenses, bilateral surgery and dropless surgery can benefit both patients and healthcare practitioners.

    Finally, Michelle is joined by Dr Magdalena Edington, a high-volume cataract surgeon who predominantly carries out dropless surgery at an Independent Service Provider in England. Magdalena provides tips for optometrists who carry out postoperative care for these
    patients in the community.

  • 55: Vitreomacular conditions – When to monitor and when to refer
    Jan 22 2026

    Vitreoretinal problems can arise as a natural part of ageing but in some patients, something more sinister could be at play. What are the signs of vitreomacular interface disorder pathogenesis that optometrists should be picking up on in practice?

    In this episode, Michelle Hanratty is in conversation with Mr Kam Balaggan, a consultant in cataract and vitreoretinal surgery at Wolverhampton Eye Infirmary. Kam describes how to identify the vitreomacular conditions that might be encountered in everyday practice — from adhesion to epiretinal membranes and macular holes. He goes on to explain when and how urgently cases should be referred.

    Michelle also asks Kam some of the questions viewers left during his recent Docet webinar, which registered optometrists can catch-up on here.

  • 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?
    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
    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
    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.
