What tests should be done for dry eye

Tests that should be performed for dry eye include tear secretion tests, tear film break-up time, tear osmolarity, tear lysozyme content, corneal topography, meibomian gland imaging, and dry eye or tear film interferometry. These tests help to assess tear secretion, tear film stability, and meibomian gland function to diagnose dry eye and determine its severity. The specific tests needed should be determined according to the specific condition of the patient and the doctor's advice, so as to formulate professional treatment and control the development of the disease.
