Filter by:The purpose of this trial is to determine the short-term effect of a self-care intervention on depression in patients with age-related macular degeneration or diabetic retinopathy.
The purpose of the study was to compare the effect of intravitreal injections of ranibizumab and aflibercept on systemic VEGF protein levels in treatment naïve wet neovascular Age-related Macular Degeneration (wAMD) patients in a detailed time course.
This is a single-arm study designed to assess the efficacy of acupuncture (Traditional Chinese Medicine) for chronic macular diseases of several types. All participants received acupuncture and massage and there is not a placebo group because it is not considered a good form to evaluate in Chinese Medicine due to, acupuncturing being a procedure is not as blind as is desired. As a control of the results in this trial, the outcomes could be contrasted against those reported in known medical publications and against expectations of the progress of the damage without treatment.
Intravitreal delivery of anti-vascular endothelial growth factor (VEGF) drugs has revolutionized the management of neovascular age-related macular degeneration (NVAMD). However, the requirement for near monthly administration of therapy coupled with the growing number of patients needing treatment has become a universal challenge in efficient delivery of care for retina physicians. While many retina practices have both increased the size of their staffs to accommodate the growing patient population and increased efficiency with the aid of digital photography, patient encounter times in clinic continue to increase, often spanning 2-4 hours. While maintaining the highest level of patient care, a streamlined alternative in the evaluation of patients with NVAMD to determine whether intravitreal therapy with an anti-VEGF agent is indicated at a particular office visit would be desirable. This multi-satellite, prospective, randomized pilot study will compare standard-of-care, physician- based retinal evaluation, defined as retinal examination by a physician and standard imaging with optical coherence tomography (OCT) and optional fluorescein angiography (FA), versus physician-guided diagnostic evaluation, defined as standard imaging with OCT and optional FA without retinal examination by a physician in the management of NVAMD with anti-VEGF therapy. Outcomes for this study are aimed primarily at demonstrating that the physician-guided diagnostic approach to managing patients with NVAMD is not inferior to the physician-based retinal evaluation based on measures such as a change from baseline in visual acuity and in central subfield thickness (CSF) on OCT. Other outcomes to be assessed in this study are length of visit times, numbers of intravitreal injections of anti-VEGF agents administered, numbers of diagnostic tests performed to determine whether treatment should be given at each visit, and frequency of retinal examinations performed for each participating patient in each cohort. Perceptions of quality of vision and patient satisfaction will be captured by interviews with patients following each clinic visit; clinical impressions of physicians will be captured by a brief physician survey. Finally, the feasibility of recruiting patients, as measured by how many eligible patients are seen at each Wilmer satellite, how many patients agree to be randomized, how many patients follow-up, and the attrition rates at the 4 and 8-month outcome visits will be assessed.
Aflibercept (EYLEA®) induces a rapid reduction in central retinal thickness (CRT) for patients suffering from neovascular age-related-macular degeneration.1 This early dramatic reduction in CRT is already observed through week 4. Therefore it might be not necessary to consistently perform each of the three monthly consecutive intravitreal injections of the so-called loading phase.
This protocol is a phase 1 clinical study to assess the safety and pharmacokinetics of ALK-001 in healthy volunteers. Please contact trials@alkeus.com for any questions.
The purpose of this study is to test the Argus II Retinal Prosthesis System in patients with severe age-related macular degeneration (AMD). The Argus II System has already been studied in completely blind patients with retinitis pigmentosa (RP). In RP patients, some cells of the retina are irrevocably damaged and the Argus II System has been found to restore some basic visual function. On these grounds, the device has received authorization for use on the European market (the CE certification) in 2011.
Background: - Maculopathies are eye conditions that affect the center of the retina. Retina health depends on the retinal pigment epithelium (RPE), a layer behind the retina. A new test may measure the health of the central retina and RPE. Objective: - To use the focal electro-oculogram (EOG) test to understand how the central retina and RPE are affected in maculopathies. Eligibility: - People at least 10 years old with a maculopathy. - Healthy volunteers with visual acuity of 20/20 or better in at least one eye. Design: - Participants will be screened with medical and eye history and an eye exam. Pictures will be taken of the eyes. - Their eyes may be dilated. - They may have a field test. They will look into a lens and press a button when they see a light. First, they may sit in the dark for 40 minutes. - Participants will have 1-7 visits over 18 months. - Their vision will be tested and eye pressure measured. - Their pupils will be dilated with eye drops and researchers may take pictures of the retina and the inside of the eye, and measure the thickness of the retina. - Participants will have an electro-oculogram. They will look at a 2 LED lights and follow them back and forth for 10 seconds once per minute. Participants will be in darkness for 15 minutes and in light for 20 minutes. One skin electrode will be placed on the nose and one next to the eye. - Participants with maculopathy will also have: - Field test. - Electroretinogram. Participants will get numbing eye drops and special contact lenses. A small metal electrode will be taped to the forehead. Participants will watch flashing lights and try not to blink. First, they may sit in the dark for 40 minutes.
The purpose of this randomized trial is to examine the effectiveness of a psycho-social "Preventive Problem Solving Intervention" on emotional well-being, change in future outlook, and vision functioning in 250 Age-related Macular Degeneration patients 60 and older.
Part A (Phase IIa): Primary objectives: The study part A is designed to investigate whether the use of regorafenib eye drops can help patients with neovascular (wet) Age-Related Macular Degeneration (wAMD) to see better after 4 weeks and 12 weeks after inclusion into this study. Secondary objectives: The study will also evaluate the safety and tolerability of the regorafenib eye drops. Part B (Phase IIb): Primary objectives: The study part B is designed to investigate: - how often the regorafenib eye drops need to be given per day - whether the use of regorafenib eye drops can help patients with neovascular (wet) Age-Related Macular Degeneration (wAMD) to see better after 4 weeks and 12 weeks after inclusion into this study. Secondary objectives: The study will also evaluate how the different dosings of regorafenib eye drops affect patients vision, the safety and the tolerability.
