Summary

Acute red eye is a common presenting complaint to primary care physicians. [1] A detailed history of the presenting symptoms and previous ophthalmic and medical history can narrow the differential diagnosis and aid in the interpretation of key examination findings. The lack of specialist equipment in the primary care setting, along with a very broad differential diagnosis, can cause difficulty in establishing the correct diagnosis, and in such cases a specialist ophthalmic opinion should be sought. [2] [3] Serious vision-threatening conditions that present as red eye are rare and can occasionally be overshadowed by associated systemic symptoms; in light of this they should always be considered within the differential and excluded on examination.
