You come across a 27-year-old male patient who complains of a painful red right eye. He mentions that the eye has been watering and he feels that his vision has worsened in the right eye. The pain has been persistent for approximately 4 days now, and he recalls that it started with a rash around his eye. He has no regular medication and is generally healthy. He wears glasses and doesn’t use contact lenses.

Upon examination, you observe that the acuity in the right eye has decreased and it appears diffusely red. The pupils are equal and reactive. You notice some crusted lesions along the lid margin. After staining the eye, you see a dendritic looking lesion which is enhanced by the staining.

What is the most probable diagnosis?
