A 50-year-old woman presents with redness, tearing, and a burning sensation in both eyes. She also complains of a sensation of something in her eyes. She has a history of Sjogren's syndrome. What could be the cause?
This patient's symptoms are suggestive of dry eye syndrome, which can cause inflammation and redness of the conjunctiva. Sjogren's syndrome, an autoimmune condition characterized by dry eyes and mouth, is a common underlying cause. Artificial tears, humidifiers, and possibly medications to stimulate tear production may be helpful.
