She complains that there is a constant dull ache in her right eye, which bores all the way to the back of the eye. The patient also reports photophobia and a right sided headache. The pain started 3 days ago and has worsened, culminating in blurry vision yesterday. On examination, the eye appeared red, with no apparent discharge, and ocular movements were globally painful.
