CASE PRESENTATION
In this case report we describe ocular changes involving simple episcleritis in a 65-year-old Chinese man with mucosal melanoma of the head and neck after treatment with interferon alfa-2b and radiotherapy. On the third day of interferon alfa-2b treatment, he began to develop simple episcleritis in his left eye. Moreover, the percentage of CD3+ T cells in lymphocytes from blood was increased after interferon alfa-2b treatment. After approximately 6 days, the symptoms of eye pain, hyperemia, and edema disappeared gradually. Then, after radiotherapy was performed three times, he again developed episcleritis in his left eye. The same symptoms of hyperemia and edema occurred again; CD3+ T cell frequency was also at a higher level. After approximately a week, all the symptoms disappeared completely. Simple treatment involving topical ofloxacin and phenylephrine was administered during the two periods of episcleritis.CONCLUSION
Episcleritis in this patient might have been due to the treatment with interferon alfa-2b and radiotherapy, leading to an increase in the level of CD3+ T cells and activation of immune system cells, which provides the guide for clinical clinicians.
