My eyes experience a mild redness (especially in the inside corners of eyes), burning, uncomfortable irritation with increased light sensitivity for the past three months that occurred initially during a trial of Xalatan (I was not wearing contact lenses at the time). I've been to three opthalmologists (one is a repected corneal/external disease specialist at university). I'm told I have no signs of infection, ocular surface is good, Schirmer test shows mild dry eye with use of punctal plugs, small sign of allergy. I tried a short course of steriod drops which relieved my symptoms, but they returned as soon as I stopped. Restasis for three months has offered no improvement. Pataday and Acular provide no benefit either. I am at a loss as to what to do next. I would greatly appreciate any direction or ideas.
