For the last year or so, the inner corners of my eyelids are extremely dry and red. They are so dry and irritated that they have both developed slits from the dryness. I have seen my internist, dermatologist and optometrist with no help. The outer corners are also dry and red. The more irritated my eyes are, I end up rubbing them and making things worse. To keep my eyes lubricated, I use Vaseline and non-preservative drops, but nothing completely clears it up. What should I do next? Is an optometrist the answer and has anyone else had this problem?
