RT Journal Article SR Electronic T1 Treatment choices for diabetic macular oedema: a guideline for when to consider an intravitreal corticosteroid, including adaptations for the COVID-19 era JF BMJ Open Ophthalmology JO BMJ Open Ophth FD BMJ Publishing Group Ltd SP e000696 DO 10.1136/bmjophth-2020-000696 VO 6 IS 1 A1 Louise Downey A1 Nachiketa Acharya A1 Helen Devonport A1 Richard Gale A1 Maged Habib A1 Vina Manjunath A1 Rajarshi Mukherjee A1 Philip Severn YR 2021 UL http://bmjophth.bmj.com/content/6/1/e000696.abstract AB First-line treatment of centrally involved diabetic macular oedema (CI-DMO) is often with an anti-vascular endothelial growth factor (anti-VEGF) agent. Although this can provide efficacy in the majority of eyes, a sizeable proportion do not respond sufficiently and many continue to receive anti-VEGF therapy after it may be optimal. This imposes a treatment burden on both patients and clinicians and, most importantly of all, can be sight threatening. Changing treatment to an intravitreal corticosteroid implant at the appropriate time may help optimise patient outcomes and reduce injection frequency, thereby reducing treatment burden.Eight retina specialists convened to discuss how to ensure eyes with CI-DMO receiving intravitreal anti-VEGF therapy are evaluated for a potential change to intravitreal corticosteroid therapy at the most effective time in their treatment journey. They concluded that clear criteria on when to consider changing treatment would be helpful and so developed a consensus guideline covering key decision points such as when and how to assess response to anti-VEGF therapy, when to consider a change to corticosteroid therapy and when and how to assess the response to corticosteroid therapy.The guideline was developed before the COVID-19 pandemic but, with the additional challenges arising from this including even greater pressure on clinic capacity, it is more important than ever to reconsider current working practices and adopt changes to improve patient care while also easing pressure on clinic capacity, reducing hospital visits and maintaining patient safety. This publication therefore also includes suggestions for adapting the guidelines in the COVID-19 era.
