4D Duke Microscope Integrated Optical Coherence Tomography in a Zeiss Artevo 800

The study team will conduct the first in-human pilot studies using 4D MIOCT for imaging in the operating room. Building on the earlier integration and wet-lab validations, the researchers will assess the system's ease of use, safety, and visualization of intended structures during various anterior and posterior segment ophthalmic procedures.

Ophthalmic AI-Assisted Medical Decision-Making

This is a multi-center, prospective clinical study designed to evaluate the application and effectiveness of an AI-assisted medical decision support system, leveraging multimodal data fusion, in ophthalmic clinical practice.

Usability User Testing of the Easy-EyeFM AI Platform

Easy-EyeFM is a code-free artificial intelligence platform designed for ophthalmologists to provide diagnostic and treatment recommendations and help doctors develop customized diagnostic models. This project aims to evaluate the usability and user-friendliness of the Easy-EyeFM platform for physicians. The study will gather feedback from medical professionals to evaluate the intuitiveness and effectiveness of the platform in supporting model customization and medical image analysis tasks. Subjects will participate in the trial of the Easy-EyeFM platform and the comparison with the existing commercial platform (AutoML) at the appointed time. The researchers will inform subjects of relevant precautions and assist them to read the user manual before the test. Subjects will complete model customization and picture diagnosis within the prescribed test time, and according to the test results, Score the human-computer interaction experience of the AI platform, fill in the questionnaire, and finally complete the evaluation content.

Ophthalmic Multimodal AI-Assisted Medical Decision-Making

This is a multi-center, retrospective clinical study designed to evaluate the application and effectiveness of an AI-assisted medical decision support system, leveraging multimodal data fusion, in ophthalmic clinical practice.

Evaluating Efficacy and Safety of Oral Melatonin in Acute Central Serous Chorioretinopathy

The goal of this clinical trial is to learn if oral melatonin can enhance visual acuity and central macular thickness in central serous chorioretinopathy (CSCR) in adults. The main questions it aims to answer are: 1. How does melatonin affect central macula thickness in CSCR? 2. How does melatonin affect visual acuity in CSCR? Researchers will compare placebo (a look-like substance that contains no drug) to see if melatonin works to treat CSCR. Participants will: 1. Take melatonin or placebo twice a day for one month 2. Visit the clinic after finishing a course of treatment, and 1 and 3 months after that for visual acuity assessment and tests 3. Keep a diary of their symptoms

Efficacy and Safety of Oral Probiotics on Ocular Symptoms and Gut Microbiome of Children with Vernal Keratoconjunctivitis

The primary goal of this study is to determine the effects of oral probiotics on the severity of ocular symptoms and the alterations of the gut microbiome of children (4-18 years old) with vernal keratoconjunctivitis. The current study will also assess the safety of oral probiotics among children with vernal keratoconjunctivitis. The main questions it aims to answer: 1- Does treatment with oral probiotics improve the severity of ocular symptoms in children with vernal keratoconjunctivitis? 2- Does treatment with oral probiotics alter the gut microbiome of children with vernal keratoconjunctivitis? Researchers will compare the ocular symptoms and gut microbiome between two groups receiving oral probiotics and placebo among children with vernal keratoconjunctivitis. Participants The participants will receive the oral probiotics and placebo ever day for one month. Record their regimen and keep a diary of their symptoms.

Hamburg City Health Study - a German Cohort Study

The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.
