Filter by:The objective of the study is to collect adaptive optics (AO) retinal images from human subjects with outer retinal diseases (diseases of the outer retina including photoreceptor, retinal pigment epithelium (RPE), basement membrane or choroidal pathologies) to develop new diagnostic methods, biomarkers, and clinical endpoints.
This is a multicenter prospective study in participants with intermediate age-related macular degeneration (iAMD). One primary objective of this study is to assess iAMD disease progression, by the timeline and rates of conversion for high-risk iAMD at baseline to more advanced atrophic AMD stages. The other primary objective of this observational study is to assess the feasibility of measuring the rate of photoreceptor loss as a potential clinical endpoint. The study will consist of an observation period of approximately 3 years (~144 weeks) for participants.
Rationale: To track performance of intravitreal distribution of anti-VEGF-A (Bevazicumab-800CW) and provide information about neovascularization and inflammation in Age-Related Macular Degeneration (AMD), thereby predicting progression and optimizing treatment Objective: To determine the safety and feasibility of fluorescence imaging of the eye with the fluorescent tracer bevacizumab-800CW for identification AMD with scanning laser angiography Study design: A non-randomized, non-blinded, prospective, single-center feasibility study. Study population: Patients group: patients with naïve wet AMD and wet AMD aged >60 years old with current treatment of anti-VEGF intravitreal. Control group: patients with naïve wet AMD and wet AMD aged >60 years old with current treatment of anti-VEGF intravitreal Intervention (if applicable): Intravenous injection of bevacizumab-800CW in the patient group and vedolizumab-800CW in the control group. Main study parameters/endpoints: Safety and feasibility of the intravenous tracer bevacizumab-800CW in patients with naïve wet AMD and wet AMD by observing the uptake in retinal, choroid and neovascular tissue. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: No risk described in other (running) studies on intravenous injection with bevacizumab-800 CW. Patients need to come back 48-96 hours after injection and the eye measurements take about half an hour longer. There is no benefit with participation.
The purpose of this study is to assess the effect of Iptacopan to prevent conversion of early or intermediate age-related macular degeneration (AMD) eyes to new incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) or late AMD.
People with the disease age-related macular degeneration (AMD) are treated with the Medical Eye Trainer (MET) system to improve their vision. The training is carried out over 2 months.
This study is a prospective, single centre, randomized, sham-controlled, double-masked, clinical trial which aims to investigate the effect of subthreshold nanosecond laser on disease progression in eyes with intermediate age-related macular degeneration (AMD) and nascent geographic atrophy by functional and anatomical outcomes. The study population will be individuals with high-risk intermediate age-related macular degeneration who meet all eligibility criteria. 60 subjects total (30 randomized to receive subthreshold nanosecond laser (SNL) treatment and 30 to receive sham treatment as per the 1:1 randomization). The study has a 12-month study period with four scheduled visits: screening, randomisation (first treatment), 6-month follow up visit (with second treatment where eligible), 12-month follow-up. The primary outcome is the proportion of laser-treated study eyes that develop late AMD compared to sham-treated study eyes over 12 months. The key secondary outcome is the change in retinal function of laser-treated study eyes compared to sham-treated study eyes over 12 months. Safety will be the proportion of laser-treated eyes that lose 10+ letters of vision (measured on a standard vision chart) compared to sham-treated eyes over 12 months.
Feasibility of the OcuDyne OPTiC System in patients with late-stage non-exudative age-related macular degeneration.
To evaluate the safety and efficacy of resveratrol, quercetin, and curcumin in combination (RQC) over 2 years in patients with age-related macular degeneration (AMD).
this study will compare the efficacy and safety of HLX04-O administered by IVT with ranibizumab in patients with active CNV secondary to AMD.
Approximately 217 million people worldwide currently suffer from low vision, which impacts a broad range of activities of daily living and is associated with depression and increased mortality. Over half of the patients presenting for low vision services have eye disease that affects the fovea and surrounding macula and leads to central vision loss (CVL). People with CVL are forced to use eccentric vision as a substitute for their impaired fovea, however eye movement control and visual function is impaired with eccentric vision. Recent evidence and preliminary results from the investigators show that rehabilitation methods can help improve oculomotor control and this can lead to improved functional outcomes. The investigators have developed new feedback-based training methods that aim to improve eccentric vision use by patients with CVL. In a series of studies, the investigators examine rehabilitation of fixation control, smooth pursuit eye movements that track moving objects and saccadic eye movements that abruptly change the point of regard. The investigators examine how visual feedback, scotoma awareness methods and hand-eye coordination can improve eccentric vision use. Improvements in oculomotor control are quantified with eye tracking methods and associated changes in visual function are quantified with acuity, contrast sensitivity and reading performance. The proposed research therefore develops and translates state-of-the-art methods in basic science to clinical applications. Accomplishing the proposed aims will provide new and improved methods for rehabilitation strategies for visual impairment. The ultimate goal of this proposal is to maximize the residual visual function of people with low vision and to help them to live independently, thereby improving quality of life and minimizing the economic and social burden of visual impairment.
