Filter by:The goal of this clinical trial is to to evaluate the changes in retinal microvasculature secondary to intra-ocular pressure changes post intra-vitreal injection in patients with diabetic macular oedema highlighting the effect of prior anterior chamber paracentesis on such changes if present . The main question[s]it aims to answer are: •[is there any effect of post intra-vitreal injection IOP spikes on retinal microvasculature?] •[is there any effect of Prior Anterior Chamber Paracentesis?] Participants in group A will be subjected to an identified approved treatment( intra-vitreal injection)& Participants in group B will be subjected to a prior ACP with the intra-vitreal injection . ]
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.
We have been using DEX for refractory DME for a long time (since 2016). Thus, we are sharing our results , evaluating both anatomical and functional outcomes of DEX therapy for refractory DME.
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.
This study was a multicenter, non-interventional, retrospective chart review of patients with DME who received ranibizumab 0.5 mg as initial intensive treatment in real-world clinical setting in Korea. Enrolled patients started receiving ranibizumab between 01 December 2019 and 31 October 2020, with records of receiving at least 3 doses in the first 4 months after starting treatment in the data collected until 30 April 2021. Subsequent dosing interval was determined by the treating physician based on the patient's condition. Data were collected for up to 24 weeks (±2 weeks) from the date of first dose of ranibizumab, including best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) results at Week 24. Subjects were identified by review of patient medical records, and those who met the inclusion/exclusion criteria were enrolled. The primary objective of this study was to evaluate the effectiveness of ranibizumab in patients with DME who received initial intensive treatment by analyzing the mean change in BCVA using data collected during the 24-week follow-up period. Central subfield thickness (CST), intra-retinal fluid (IRF), sub-retinal fluid (SRF), edema improvement, and Diabetic Retinopathy Severity Scale (DRSS) results were also assessed to further analyze the effectiveness of ranibizumab. The total number of ranibizumab doses administered was obtained to determine the pattern of ranibizumab treatment in real-world clinical setting. All decisions regarding the clinical management and treatment of patients were made by the treating physician according to real-world routine practice, independently of the study. All data collected in this study were extracted from the patient medical records recorded in the process.
The aim of this study is to assess the association between vitreous hyper-reflective dots (VHD) and the macular thickness changes following uneventful phacoemulsification. In this prospective study the investigators performed optical coherence tomography (OCT) imaging in patients undergoing cataract surgery preoperatively and postoperatively after 1 week, 1 month and 3 months and analyzed the OCTs for VHDs. The investigators then measured the macular thickness in patients with VHDs and without VHDs and correlated the macular thickness with the number of VHDs.
A Phase 1 study to assess the safety and efficacy of OCU200 for center-involved diabetic macular edema
The goal of this clinical trial is to clarify the efficacy of anti-vascular endothelial growth factor (anti-VEGF) drugs combined with subthreshold micropulse laser (SML) therapy on retinal function and anatomical recovery in patients with diabetic macular edema (DME). The main questions it aims to answer are: - To clarify the efficacy of anti-VEGF drugs combined with SML therapy on retinal function and anatomical recovery in DME patients. - To explore the changes in visual acuity and optical coherence tomography angiography (OCTA) parameters before and after the treatment of DME with anti-VEGF drugs combined with SML, and further explore the changes in morphological characteristics of retinal microvessels and the potential treatment mechanism. Participants will randomly be given Intravitreous injection of anti-VEGF drugs or anti-VEGF drugs combined with SML therapy. All participants will be followed up for 6 months after treatment.
