BACKGROUND AND OBJECTIVEAmong the main causes of blindness and severe vision loss are age-related macular degeneration, diabetic macular oedema, and retinal vein occlusion. The «Do Not Do» recommendations are strategies to improve quality of care and optimise healthcare costs. The aim of this study was to establish, by consensus, practices of low value in the above-mentioned pathologies, in addition to estimating their occurrence. MATERIALS AND METHODSMixed methods study including a first phase of consensus of a multidisciplinary panel of experts using the Nominal Group technique. In the second phase, a retrospective observational study was conducted, by conducting a review of medical records. RESULTSA total of 7 recommendations were established for age-related macular degeneration, 4 for diabetic macular oedema, and 5 for retinal vein occlusion. A total of 1,012 medical records were reviewed by the 4 participating hospitals. The review of medical records revealed that agreed «Do Not Do's» occurred in a range between 0.6% and 31.4% of the cases included in the study. CONCLUSIONSThis study identified «Do Not Do» recommendations in these pathologies that occur relatively often in clinical practice. It is necessary to review the healthcare processes that will enable these practices to be eradicated, and the quality of care to be improved.
