I suffer from constantly burning eyes.Doctors tentatively think it could be dry eyes . I am 28,female and am not on any prescription drugs or pills. I have noticed that in times of high anxiety, my mouth goes dry and stays that way for a few days. In these times, my eyes feel perfectly normal. However the eye burning and strain returns once the dry mouth abates. Can all this be due to sustained depression? I suffer from no other depression symptoms or any other disease. I work on the computers and find it really hard to go on after a short while. I do warm compresses and use tear drops every few hours. I have got autoimmune tests to check for Sjogrens and they came back negative. My TSH and blood/urine sugar/Blood pressure are in the normal levels too. My blood tests showed a slightly lower than normal lymphocyte and basophil count. ESR is normal. Is there any explanation for this? The dry eye has persisted for 7-8 months now.
