Key inclusion criteria
Dry eye group
1. Those who plan to go to an ophthalmology outpatient in Keio University Hospital to be performed dry eye examination and medical treatment
2. Those who are 30 years old or older and have voluntarily agreed to their documents
3. No history of keratoconjunctival surgery within the past year
4. Dry eye patients diagnosed as dry eye that meet the dry eye diagnostic criteria
(Attachment) Dry eye diagnostic criteria 2016 version (Dry eye study group)
1) Subjective symptoms of dry eye such as eye discomfort and abnormal visual function
2) Tear break up time (BUT) is 5 seconds or less
A positive finding for all parameters was considered grounds for a positive diagnosis of dry eye.
Normal group
1.Those who wish to participate in the research as volunteers who are visiting the ophthalmology clinic
2. Those who are 30 years old or older and have voluntarily agreed to their documents
3. No history of keratoconjunctival surgery within the past year
4. Meets the conditions 1)-3) below parameters
1) There are no subjective symptoms of dry eye such as eye discomfort or visual dysfunction
2) BUT is 6 seconds or more
3) No keratoconjunctival epithelial disorder
Key exclusion criteria
Exclude people who meet any of the following conditions from both dry eye group and control group
1. Those who do not agree with the ophthalmic examination
2. Those who do not consent to tear collection
3. Those who have a history of keratoconjunctival surgery within the past year
