Sunglasses for painful red eye.

We present the case of a 62-year-old man who developed an acutely painful red eye with severe photophobia while in an oncology ward after spinal radiotherapy. In a joint effort between palliative care, oncology and ophthalmology clinicians, he was diagnosed with herpes simplex viral keratitis. This was treated with topical and systemic antiviral medication, as well as corticosteroids. Alongside analgesics, he also benefited from a pair of sunglasses for severe, painful photophobia.
