Filter by:The purpose of this study is to evaluate the efficacy and safety of Aflibercept (produced by CinnaGen Co, Iran) compared with Eylea® (Regeneron, USA) in subjects with Neovascular Age-related Macular Degeneration (nAMD). All the participants will receive one of the following regimens: Aflibercept (CinnaGen Co, Iran) or Eylea® (Regeneron, USA), 2 mg (vial 0.05 ml) by intravitreal injection every 4 weeks for the first 3 injections, followed by 2 mg every 8 weeks until week 48 of study. The primary objective of this study is to verify the non-inferiority of Aflibercept (CinnaGen Co, Iran) versus Eylea® (Regeneron, USA) in achieving maintaining vision (losing<15 letter on ETDRS chart) at week 52 in comparison to week 0 in participants with Neovascular AMD.
A study is conducted to determine the effectiveness of prism spectacles in improving visual acuity with age related macular degeneration patients and to assess the improvement in quality of life in patients by using prism spectacles.
The aim of this study is to evaluate the quality of life of AMD patients related to vision using the short version of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25), patients' social support, and their relationship with demographic and clinical variables.
Many patients will have underlying maculopathy present when undergoing cataract surgery, which are not visible on fundoscopy alone. Knowledge of this underlying pathology will allow an improved consenting process and discussion with the patient regarding the risks, visual prognosis and recovery following cataract surgery. Incidental findings in the fellow eye would also allow for improved diagnosis and management of these patients without adding significant additional time to specialist high volume cataract assessment clinics.

In this study, the study team utilize virtual reality (VR) to simulate visual impairments of different types and severity in healthy subjects. The platform implements three of the most widespread forms of visual impairment in the United States (US): age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma, each with three levels of severity, (mild, moderate, and severe). At present, glaucoma is further developed toward a multidimensional visual impairment simulation. The platform is utilized: i) to provide a safe, controllable, and repeatable set of environments for development and preliminary testing of electronic travel aids (ETAs) in a variety of conditions (i.e., using the ETA to navigate in the immersed environment); and ii) to equip blind and low vision (BVI) professionals, inclusive of orientation and mobility (O&M) instructors, with a controlled, tunable training platform for skill/capacity building, assessment, and refinement of O&M techniques, as well as visually impaired trainees with a safe and immersive environment to improve their O&M skills and learn novel techniques. Two sets of hypothesis-driven experiments are proposed to assess the feasibility of the platform with respect to these two objectives.
This study will evaluate the safety, tolerability, pharmacokinetics and preliminary efficacy of HLX04-O administered every 4 weeks in participants with wet age-related macular degeneration (wAMD)
Age-related macular degeneration (AMD) is the leading cause of visual impairment in the UK. The condition is characterised by damage to the region of the retina (macula) responsible for detailed central vision, this leading to problems with tasks such as reading and face-recognition. The ability to accurately measure vision is central to the detection and management of AMD. The most common test (visual acuity) typically requires patients to identify black letters of varying size on a white background, with the smallest letter read representing the limit of vision. Conventional tests are however known to be variable, making it difficult to determine if a true change in vision has occurred. Previous work has found the Moorfields Acuity Chart, which contains specially constructed letters composed of a black core and white border, to be more sensitive to early AMD compared to standard charts. Despite this advantage, it is unclear if there is an associated increase in measurement variability with the Moorfields Acuity Chart and if this changes with the severity of disease. In this study, the relationship between vision test sensitivity and measurement variability will be quantified with both conventional visual acuity tests and the new Moorfields Acuity Chart to identify the optimal vision test to detect and monitor AMD in the clinic.
This study is a single-center, open label, 4-month study, designed to evaluate the safety and treatment efficacy of RBM-007 in patients with intraretinal or subretinal edema due to previously untreated neovascular AMD. Up to 5 subjects will be randomized to receive study medication. Study treatment will be administered by intravitreal injections.
This will be a double masked, randomized, placebo controlled, single and multiple oral dose study conducted in 3 parts. The safety and tolerability of single and multiple ascending oral doses of QA102 in healthy young and older adult subjects will be evaluated. The study will also characterize the pharmacokinetic (PK) profile of QA102 in plasma and urine after single and multiple oral doses of QA102. Besides, the metabolite profile of QA102 will also be characterized. Part 1 will comprise a single dose, sequential cohort design. Part 2 will comprise a multiple dose, sequential cohort study. Part 3 will comprise a multiple dose, single cohort study in older subjects.
