Diabetic retinopathy (DR) is one of the most serious microvascular complications of diabetes. Early diagnosis and treatment of diabetes is the key to prevent visual impairment in DR patients. This study aims to use a non-targeted metabolomics detection technique combined with ultra-high performance liquid chromatography time-of-flight mass spectrometry to analyze the metabolomics profile in aqueous humor sample of DR patents, and further explore the mechanism of the relationship between differential metabolites and their metabolic pathways with NLRP3 activation in DR inflammatory damage. DR patients with macular edema will receive anti-vascular endothelial growth factor (anti-VEGF) treatment; these patients will be divided into two groups: responders group and non-responders group.
This study will demonstrate that tarcocimab 5 mg is superior to sham treatment in participants with moderately severe to severe NPDR.
The goal of this observational study is to observe the formation and development of the non-perfusion area of diabetic retinopathy in the posterior area of the retina in type 2 diabetes patients aged 18-75 years old, who can cooperate with all examinations and sign informed consent, clinical myopathy examination and Optos 7 field of vision with mild than severe NPDR, and no other exclusion indicators.The main questions it aims to answer are whether posterior retinal non-perfusion area occurs earlier than peripheral non-perfusion area and whether the rate of non-perfusion area expansion is a risk factor for the progression of diabetic retinopathy. Participants will have protocol-specific follow-up examinations at 1, 2, 3, 4, and 5 years (± 3 months). Additional visits are made as required by the study and the patient's condition. The contents of follow-up examinations are: History of other diseases, medications being used, eye diseases, surgeries, treatments, height, weight, and blood pressure. Best corrected vision, logarithmic visual acuity chart. Tupai OCTA, 24×20mm range, 6×6mm range scan. Optos fundus imaging, color and no red light images. Fundus fluorescence angiography (only preliminary examination for the first time found mild to moderate NPDR patients, who have been angiographed in the past, only at the 5th year, or as required by the condition). Glycosylated hemoglobin. Creatinine, urea, glomerular filtration rate. Total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol. Urinary microalbumin/urinary creatinine ACR. Microvisual field.
The goal of this clinical trial is to perform a detailed description of the feno- and genotype of people living with type 2 diabetes and severe obesity who are linked to care at Steno Diabetes Center Greenland. The main questions it aims to answer are: - Are monogenetic diabetes variants associated with the same risk of developing late diabetic complications as other types of diabetes? - Can genotyping and thereby personalized medicine be implemented in Greenland, and can personalized medicine lead to improved treatment? - What is the prevalence of sleep apnea among high-risk individuals in Greenland? - Is it possible to develop and implement a simple algorithm for the identification of sleep apnea in Greenland that can ensure treatment of severe sleep apnea? 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.
