Red Eye

In this podcast we discuss the case of: 44 year old female who presented at 4am in the morning with an acutely red and painful right eye. She had thought that the eye had started to feel a bit irritated that evening on returning from work and it had steadily worsened from there. She came to the ED as she couldn’t get off to sleep on account of the discomfort and felt as though there was something in the eye. She described some increased tearing but no discharge and mild blurred vision. No flashers or floaters. There was an associated mild headache, with mild photophobia. She denied trauma. She had been well recently. Contact lens wearer, often works very long hours and does not always take them out to sleep and perhaps does not change them as suggested.
