Dry eye examination mainly includes tear secretion test examination, tear film rupture time examination, and comprehensive ocular surface analyzer examination. Dry eye is a common ophthalmologic condition that causes patients to experience symptoms such as dryness, stinging, foreign body sensation, and photophobia. Patients need to confirm the diagnosis and assess the severity of the condition by doing dry eye related tests. Tear secretion test can be done to see if the amount of tear secretion is normal, and tear film rupture time test can be done to assess if the quality of tears is normal. A comprehensive ocular surface analyzer can be used to observe the stability of the tear film and to determine whether the blepharoplakic glands are atrophied. The diagnosis of dry eye requires timely treatment. At present, the main way to relieve the symptoms is by applying artificial tear drops in the eye, commonly used are sodium vitrate eye drops and polyethylene glycol eye drops, etc. In addition, the underlying causes should be actively removed. Dry eye patients should go to the ophthalmology department of the hospital for examination in a timely manner, after a clear diagnosis, under the guidance of the doctor to use medication.
