The red eye is a frequent presentation in general practice. While most commonly benign or self-limiting, the red eye may be due to serious sight-threatening causes and require urgent management. A systematic approach to this condition is essential. Slit lamps are uncommon in Australian general practice and GPs need to have satisfactory skills in eye examination and ophthalmoscopy. GP registrars are likely to have had some experience in assessing the red eye in the ED setting – however, supervisors need to assess registrar competence in managing this condition in the general practice setting, and appropriately facilitate learning of the necessary knowledge and skills.
