Participants will: - Answer WHO-5 and FOSQ-10 questionnaires regarding quality of life and functional outcomes of sleepiness - Perform VAGUS examinations for Cardiovasculare Autonomic Neuropathy - Clinical examination of height, weight, circumference of hip, waist and neck, Friedman tonsil and tongue score, nasal air flow, nasal septal deviation - Blood samples for full genome sequencing
An online survey (n=1,500) and 4 focus groups will be conducted with Latinx patients with diabetes (n=20) to obtain preliminary data regarding whether and how patient and clinician video testimonial interventions (n=6) increase eye health literacy and trust in healthcare.
The goal of this clinical trial is to learn about the performance of the AEYE-DS Software Device to automatically detect more than mild Diabetic Retinopathy (mtmDR) in adult participants diagnosed with Diabetic Mellitus (DM) using fundoscopic images of the eyes. The main question it aims to answer is if the software is effective in diagnosing more than mild Diabetic Retinopathy (mtmDR) in patients with known diabetes using digital funduscopic images, acquired from each of the participating fundoscopy devices and based on one macula centered image per eye. Participants: - will have an eye exam in which photographic images of each eye will be taken by a novice operator, using four different FDA approved/registered fundoscopy cameras. These images will be sent to and analyzed by the AEYE-DS software device. - will have additional eye imaging taken using a different FDA approved desktop camera system by a professional ophthalmic photographer. These images will be sent to an independent reading center for analysis. - will have dilation drops put in their eyes (either during or after the imaging with the fundoscopy cameras), wait about 30 minutes for the pupils to dilate and continue the eye imaging exams. The outcome results with the AEYE-DS Software will be compared to the analysis of the eye images processed by the reading center to see if the investigational software device was accurate in its diagnosis.
The researchers have used the ophthalmology textbook, clinical guideline consensus, the Internet conversation data and knowledge base of Zhongshan Ophthalmology Center in the early stage, combined with artificial feedback reinforcement learning and other techniques to fine-tune and train the LLM, and developed "Digital Twin Patient", a localized large language model that has the ability to answer ophthalmology-related medical questions, and also constructed a combination of automated model evaluation and manual evaluation by medical experts. The evaluation system combining automated model evaluation and manual evaluation by medical experts was constructed at the same time. This project intends to integrate "Digital Twin Patient" into undergraduate ophthalmology apprenticeship, simulate the consultation process of real patients through the online interaction between students and "Digital Twin Patient", explore the effect of "Digital Twin Patient" consultation teaching, provide emerging technology tools for guiding medical students to actively learn a variety of ophthalmology cases, cultivate clinical thinking, and provide the possibility of creating a new mode of intelligent teaching.
Eye health is of great importance for quality of life. Some eye diseases can progress and cause permanent damage up to vision loss if they are not treated early. Therefore, it is of great importance to have regular eye examinations and to detect possible eye diseases before they progress. Healthy people should also undergo eye screening once a year, and those with any complaints regarding eye health should be examined. With the advancing technology, Artificial Intelligence (AI) has begun to play a significant role in the healthcare sector. Retinal diseases, serious health problems resulting from damage to the back part of the eye's retina, include conditions such as retinopathy, macular degeneration, and glaucoma. Artificial intelligence, with its visual recognition and analysis capabilities, holds great potential in the early diagnosis of retinal diseases. AI-based diagnosis of retinal diseases typically involves the use of specialized algorithms that analyze retinal images. These algorithms identify abnormal features in the eye, providing doctors with a quick and accurate diagnosis. EyeCheckup v2.0 will diagnose glaucoma suspicion, severe glaucoma suspicion, age-related macular degeneration diagnosis, RVO diagnosis, diabetic retinopathy diagnosis and stage, presence/absence of DME suspicion and other retinal diseases from fundus images. This study is designed to assess the safety and efficacy of EyeCheckup v2.0. The study is a single center study to determine the sensitivity and specificity of EyeCheckup to retinal and optic disc diseases. EyeCheckup v2.0 is an automated software device that is designed to analyze ocular fundus digital color photographs taken in frontline primary care settings in order to quickly screen.
Diabetic retinopathy is a common complication of diabetes and one of the leading causes of low vision and blindness in adults. In recent years, the prevalence of diabetes and the incidence of diabetic retinopathy have increased significantly in our country. Epidemiological studies show that the prevalence rate of diabetes in China is 12.8%, and the prevalence rate of DR in adult diabetic patients is 24.7%-37.5%, that is, there are about 3200-48 million DR patients in China, and the patients have a trend of younger people. DR has become a serious public health problem threatening people's lives and health. At present, it is known that the pathogenesis of DR is related to hypoxia, oxidative stress, inflammation, abnormal expression of cytokines and gene methylation, but the specific pathogenesis has not been fully clarified. Due to the hidden early symptoms of DR, the lack of basic screening conditions in primary medical and health institutions, and the lack of awareness of DR by patients themselves, many DR patients have already appeared serious retinopathy when they seek medical treatment, resulting in irreversible visual function impairment. In addition, the current clinical treatment methods for DR mainly include retinal photocoagulation therapy, intraocular anti-VEGF drug injection and vitrectomy surgery, etc. These methods are aimed at relatively severe diabetic retinopathy, and there is no effective treatment method for early diabetic retinopathy that can prevent or slow down the occurrence and development of DR. Therefore, to further explore the pathogenesis of DR and develop new therapeutic methods has become an urgent problem. Exosomes are extracellular vesicles secreted by living cells with a diameter of 40-150nm. With a bilayer lipid membrane structure, exosomes contain a variety of biomolecules such as lipids, proteins, nucleic acids, cytokines, and autoantigens, and are important mediators for the transmission of biological information between cells. Almost all cells can secrete exosomes, and exosomes from different cells have different functions. Exosomes transfer their contents to nearby or distant cells and participate in cell growth, angiogenesis, immune regulation and other processes. Previous studies have shown that exosomes secreted by various cells in the retina are present in the vitreous and aqueous humor of patients and play an important role in the pathogenesis of DR. At the same time, exosomes in the systemic circulation of diabetic patients can also reach the retina through the blood circulation, participate in the initiation process of DR And play an important role. At the same time, due to the double-layer lipid membrane structure, exosomes can also target the coated components to specific cells and tissues through biological barriers such as blood-brain and blood-eye, which is expected to become a highly efficient drug delivery route. Therefore, the role of exosomes in DR Treatment has also attracted much attention.
In this phase IV, randomized, double-masked, sham-controlled study the investigators hope to determine the efficacy in peri-operative faricimab (Vabysmo) compared to sham in limiting complications from pars plana vitrectomy for diabetic vitreous hemorrhage with or without tractional retinal detachments.
Objective: Explore the biomarkers related to proliferative diabetic retinopathy by analyzing the protein expression profile changes of plasma exosomes in patients with difference phases of diabetic retinopathy, and investigate potential molecular mechanisms and therapeutic targets. Methods: Enrich exosomes from plasma by column extraction method. NTA, WB and TEM were used to characterize the obtained exosomes, and exosome proteinomics was performed by chromatography⁃mass spectrometry. Corhorts: The study was divided into four groups: a healthy control group, a diabetic without diabetic retinopathy group, a non-proliferative diabetic retinopathy group, and a proliferative diabetic retinopathy group, with 6 cases in each group.
