Filter by:The study used a new surgical technique: intraoperative fluorescence imaging,In the 1980s, some scholars proposed the concept of intraoperative fluorescein angiography.During vitrectomy, intraoperative fluorescein angiography under 3D microscope can guide the surgeon to observe the non-perfusion area and new blood vessels on the same screen for accurate retinal photocoagulation therapy.Through this technology, the primary retinal disease can be identified in time after the removal of vitreous hemorrhage during surgery, providing effective imaging evidence support for the design of further treatment.
The purpose of this pilot study is to evaluate different imaging parameters in patients with previously treatment-naive DME and ME due to RVO before and after treatment with dexamethasone implant, in order to find specific retinal inflammatory and microvascular biomarkers that may be predictive of treatment outcome.
The purpose of this study is to assess the sensation of ocular dry eye symptom after an intravitreal injection of anti-VEGF.
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.
This is a open label, multicenter, Phase II study to evaluate the usability of the pre-filled syringe (PFS) of SB11 (ranibizumab biosimilar). Healthcare Professionals (HCPs) followed the Instructions for Use (IFU) to prepare and administer SB11 PFS with intravitreal injection to subjects with nAMD or Macular Oedema Secondary to RVO.
Several studies have indicated a relation between the development of RVO and elevated intraocular pressure (IOP) and glaucoma [9]. Further investigations into the structural alterations in the fellow eyes of individuals with unilateral RVO have revealed that the pRNFL is thinner than in healthy eyes, suggesting that there may be systemic risk factors for both RVO and glaucoma
Researchers are looking for a better way to treat people who have macular edema secondary to retinal vein occlusion (RVO). In people with RVO, a blood vessel that carries blood away from the retina (vein) becomes blocked. The retina is the very back part of the eye. The blocked vein causes fluid and blood to leak into the retina and thereby causes a swelling of the macula (the center of the retina responsible for fine vision). This swelling is called macular edema. When a vein in the retina is blocked, the levels of a protein called vascular endothelial growth factor (VEGF) rises. VEGF helps the growth of new blood vessels. This can lead to macular edema and may cause the vision to become blurry. The study treatment intravitreal (IVT) aflibercept is given as an injection into the eye. It works by blocking VEGF and this can help repair vision problems related to RVO. IVT aflibercept is already available and is prescribed by doctors as the standard of care treatment for macula edema secondary to RVO. Standard of care is a treatment that medical experts consider most appropriate for a disease. Standard of care is given every 4 weeks in people with macula edema secondary to RVO. While repeated injections of aflibercept may prevent worsening of vision, it may place a burden on the patient. However, a higher amount (8 mg) compared to the standard of care (2 mg) of IVT aflibercept is being tested in studies. This higher amount could be given less often. The amount of IVT aflibercept given is measured in milligrams, also known as mg. The main purpose of this study is to learn how well a higher amount of the study treatment aflibercept works in people with macular edema secondary to RVO. To answer this, researchers will measure changes in vision called best corrected visual acuity (BCVA) in the study participants between study start and after 36 weeks of treatment. Changes will then be compared between those participants who received the higher amount of IVT aflibercept and those that received standard of care. To learn how safe the study treatment is in the participants, the researchers will count the number of participants from study start and up to 64 weeks later that have: - adverse events - serious adverse events "Adverse events" are any medical problems that the participants have during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think they might be related to the study treatments. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important. Dependent on the treatment group, the participants will either receive the higher amount of aflibercept or standard of care as an intravitreal injection for up to 60 weeks. The study will consist of a test (screening) phase, a treatment phase and an end of study phase. Each participant will be in the study for up to 64 weeks. One visit to the study site is planned during the screening phase, followed by visits approximately every 4 weeks (16 in total) during treatment and one visit at the end of the study. During the study, the study doctors and their team will: - check patients' eye health using various eye examination techniques - measure patients' eye vision (BCVA) - take blood and urine samples - do physical examinations - check vital signs - examine heart health using electrocardiogram (ECG) - do pregnancy tests in women of childbearing age In addition, participants will be asked to fill a questionnaire on vision-related quality of life.
Background and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
The investigators have worked with software designers to develop a software that allows us to analyse current adherence to guidelines on Ophthalmic conditions such as Age related Macular Degeneration (AMD), Diabetic Macular Edema (DMO) and Retinal vein occlusion (RVO). National guidelines state that those patients with fluid accumulation in their central macular, meeting criteria, are eligible for injections into the vitreous cavity of the eye (intravitreal).(1) As these condition are common the trial is relevant to the public and patients as future management may be affected by the outcomes of this trial. The investigators will trial the software which uses Artificial Intelligence (AI) algorithms to determine the most suitable review required for patients being managed in clinics, based on 'Vision' and 'Retinal Thickness' demographics. This will be done prospectively, in real time. The question to be addressed is 'Can medical and non-medical practitioners accurately determine treatment and follow-up for patients assisted by an AI clinical decision support system, for the three most common chronic macular diseases - Wet Age-Related Macular Degeneration (wAMD), Diabetic Macular Oedema (DMO) and Retinal Vein Occlusion (RVO) - in a safe and clinically cost effective way?' Patients undergoing treatment for at least 12 months are eligible to participate, so long as they are able to provide consent for their data to be used. Participants will have no change to their care during the trial. The study, will take place at Guy's and St. Thomas' NHS FT (GSTT) from where participants will be recruited, and will last approximately 6 months of data collection. The software will be used by the research Fellow, alongside the masked consultant. Therefore the patient pathway and management will not be impacted by this trial. Patients will be consented for data use.
