Investigator-initiated Clinical Trial to Observe Conjunctival Goblet Cell Using an Anterior Segment Imaging Device
Trial Parameters
Brief Summary
Conjunctival goblet cells secrete mucin, vital for tear film stability. Dysfunction can cause tear film issues and lead to diseases like dry eye. Imaging these cells is crucial for diagnosis and treatment. 0.5% moxifloxacin eye drops, an FDA-approved antibiotic, are used to treat bacterial eye infections and prevent infections before surgeries. The investigators developed a non-invasive imaging method for goblet cells, validated in animals, and now plan to test it in humans for diagnosing and treating ocular surface diseases.
Eligibility Criteria
Inclusion Criteria: * Adult patients aged 19 years or older. * Patients who are currently using or scheduled to use 0.5% moxifloxacin eye drops for ophthalmic surgery (control group) or for ocular surface diseases (patient group: dry eye, Sjogren's syndrome, Stevens-Johnson syndrome, graft versus host disease). * Patients who have agreed to understand and comply with the clinical trial protocol's plans for medical examinations and follow-up observations. Exclusion Criteria: * Pregnant or planning to become pregnant, and lactating women. * Patients with intellectual disabilities and other psychiatric disorders who, at the discretion of the investigator, are deemed ineligible for participation in the clinical trial. * Patients with hypersensitivity reactions to 0.5% moxifloxacin eye drops, or patients for whom administration is contraindicated. * Patients for whom participation in the study is deemed impractical based on the judgment of other medical staff and neutral observers (excludin
