Dry, itchy eyes are not a sign of glaucoma, but should be considered to be due to dry eye with allergic conjunctivitis. Dry eye patients will experience symptoms such as dryness, stinging, and foreign body sensation due to insufficient tear production in the eyes, or due to overuse of the eyes, a dry environment, and other underlying diseases such as lupus. Allergic conjunctivitis, on the other hand, can be caused by the irritation of allergens that cause the eyes to become sensitized, which manifests itself in symptoms such as dryness and itchiness of the eyes. The frequent combination of dry eye and allergic conjunctivitis is related to the fact that dry eye patients have fewer tears and are unable to successfully flush out the allergens adhering to the surface of the eye; these manifestations are not caused by glaucoma. The main manifestations of glaucoma patients are eye congestion, redness, swelling, pain, narrowing of the visual field, vision loss, etc. A clear diagnosis can be made by going to the ophthalmology department of the hospital for ocular pressure examination, funduscopic examination, visual field examination, and so on. If the dryness and itchiness of the eyes persist, you should consult a doctor for a clear diagnosis and standardized treatment under the guidance of the doctor.
