39 Clinical Trials for Various Conditions
This study is exploratory and examines whether the best-corrected visual acuities (BCVA's) from trial frames created with the refraction results obtained from a novel handheld optical device yields results similar to the ophthalmic refraction obtained from an autorefractor in healthy volunteers age stratum of 18 through 65 years.
This study was intended to test if reframing an offer for a free follow-up eye examination could increase uptake within ongoing community-based screening program for low-income and minority populations in Baltimore City. This study evaluated the effect of offering participants a physical voucher they were told was redeemable for free follow-up, relative to simply telling participants that the follow-up appointment would be free of charge. The investigators assessed two forms of vouchers, one with estimated value information, and one without. The underlying hypothesis was that reframing these already free offers would increase uptake by increasing perceived offer value and increasing a sense of regret from not taking advantage of a "good deal."
Glaucoma is a blinding eye disease increasingly common in older adults, particularly in African Americans, and often diagnosed late in the disease course. It is essential to develop novel health care models, utilizing telemedicine, to improve the ability to detect glaucoma at an earlier stage, and to provide a platform to manage this disease in community-based clinics so that further vision loss is prevented. Our goal is to improve the quality and accessibility of glaucoma detection and management among a vulnerable and at-risk segment of our population.
Single-center, open-label, prospective study in healthy volunteers desiring refraction for correction of visual acuity to compare a handheld device supported by a mobile application with the phoropter and autorefractor.
The purpose of this research study is to determine whether involvement with a social worker helps reduce distress, depression, and increase patient activation in participants over a 6 month intervention period. The study will also describe common barriers to care that participants face.
The overall objective is to develop the hardware systems and software algorithms necessary to make accurate measurements of the whole eye with optical coherence tomography (OCT). The research procedure that each subject will undergo is imaging with the OCT system. Three populations will be included: 1. Normals to ensure the imaging range of the system, 2. Patients with previous LASIK who will be undergoing cataract surgery, and 3. Patients with a history of cataract surgery or high myopia. The third group will also undergo MRI imaging for comparison. There are no known risks to the subject from imaging with optical coherence tomography beyond what is normal for standard ocular photographic procedures. Light exposure is below ANSI limits. In groups 2 and 3, clinical parameters drawn from the OCT images will be compared to standard of care imaging.
The purpose of this study is to compare the Technology-based Eye Care Services (TECS) protocol to the standard face to face ophthalmologic exam.
Randomized, double-masked, controlled, 2-arm parallel group, multi-site, 3-month dispensing study of Johnson \& Johnson Vision Care, Inc. (JJVCI) Investigational contact lens, compared with a marketed, monthly replacement contact lens. Subjects will wear the JJVCI investigational contact lenses on a daily wear basis.
The project aims to determine the effectiveness of a patient-centered health care delivery system focused on improving follow-up adherence in patients diagnosed with glaucoma. Over the course of 1 year, a 6-person team comprised of one attending physician; project managers and community health educators, ophthalmic technician, and patient navigators will complete a baseline visit, baseline assessment and 2-3 follow-up visits. The patient navigator will assist participants in community groups and a portion of the office-based participants with scheduling follow-up appointments
This study aims to examine the effectiveness of three different ways of helping patients attend their recommended eye care appointments.
The goal of this project is to implement a Collaborative Translational Research Center (TRC) Network Study which aims to assure optimal two-way communication between ophthalmologists and their patients' primary care physicians (PCP). The Collaborative TRC Network Study will have 2 objectives: * To design and develop common research protocols to develop a 4-year retrospective database (2007-2010) that compiles electronic billing and medical chart information that can be used to study individual-level, clinical-level and system-level factors that impact access to and quality of vision care; * To evaluate adherence to dilated fundus exams (DFEs) follow-up as the primary measureable quality indicator, and its relationship to the patients' demographics, ethnicity, socioeconomic status (SES), severity of diabetic retinopathy (DR), other ocular and medical co-morbidities, presence of HA1C, and primary care provider (PCP) communication. By enhancing communication and strengthening the clinical information exchanged between PCPs and eye care professionals, this Collaborative TRC Network study will help to overcome barriers to obtaining ongoing DFEs and reduce disparities in vision care utilization.
Pt. 1 Diabetic retinopathy is a common eye condition among diabetic adults and can lead to severe vision impairment and even blindness. African Americans are more likely to have vision loss from diabetic retinopathy due to a variety of factors, including cultural barriers to care. The investigators aim to increase the rates of eye exams in diabetic African American adults by providing culturally relevant home-based interventions. These interventions will increase the knowledge about diabetes and the eyes and the awareness of ocular risks due to diabetes. 206 African American adults, over the age of 65, with diabetes will be recruited from primary care clinics at Thomas Jefferson and Temple University. Eligible patients who consent to participate will have baseline information taken about medical and ocular history, understanding of diabetes and a hemoglobin A1C level obtained. The subjects will then be randomized to one of two treatment conditions: Behavioral Activation or Supportive Therapy, each of which will be delivered over 4 sessions. Behavioral Activation will consist of educational materials, referral assistance for eye clinics, and addressing patient specific barriers to care. Supportive Therapy will consist of supportive but non-directional interaction with the patient exploring the impact of aging and diabetes on the patient's life. The investigators hypothesize that more patients who receive Behavioral Activation will have a dilated fundus exam (the primary outcome variable), understand the risks of diabetic complications and feel less depression then subjects who receive Supportive Therapy.
The study design is a randomized intervention evaluation. Ten senior centers in predominately African American communities in the Birmingham, Alabama will be selected as sites for the educational intervention. Five centers will be randomly assigned to receive an educational intervention communicating practical information about vision, eye conditions and eye care as pertinent to the older African American population. The other five centers will serve as social-contact controls, where participants will receive an engaging information session on a non-health related topic. The primary outcome of interest is the change in percentage of persons receiving comprehensive eye care from pre- to post- intervention. The secondary outcomes are the process outcomes of improvement in knowledge, attitudes, and values about vision, eye conditions, and eye care.
Study in the US intended to evaluate the safety and effectiveness of a Johnson \& Johnson Vision Care Inc, (JJVCI) contact lens for use on an extended-wear basis for up to 7 days (6 nights).
The study's primary objective is to determine whether the PRSS improves the optimal timing of photocoagulation in diabetic patients in VA. Secondary objectives include assessing if the program: (1) leads to improved compliance with retinopathy screening and surveillance visits; (2) improves patient and provider satisfaction with VA diabetic eye care; (3) reduces eye care visit rates among diabetics receiving eye care at VA; (4) decreases health care resource utilization; and (5) improves the cost-effectiveness of eye care for patients with diabetes
The primary study outcomes are to investigate the effects of 4-month daily carotenoid complex supplementation on carotenoid status in the macula and skin and visual fatigue among adults 20-45 years of age. Secondary outcomes will examine the supplementation effects on cognitive function.
The purpose of this project is to test two different types of health messages, one that is developed for a specific group (targeted) and the other that is more personalized to individuals (tailored), to see which is better at changing how often people have their eyes examined. We hypothesize that people who get the tailored messages will be more likely to get a dilated eye exam than people who receive the targeted messages.
The purpose of this research is to evaluate if intervention and education can change the behavior of someone's willingness to see an eye care provider to prevent blindness and glaucoma. The researchers are investigating if adding additional resources improves participant access to care.
Open label exploratory study of the EyeQue Insight in healthy volunteers \>=7 years of age.
The investigators are conducting a 5-year prospective, 2:1 cluster-randomized controlled trial, funded by the Centers for Disease Control (CDC), which provides vision screenings to underserved New York City residents living in affordable housing buildings in Harlem and Washington Heights.
The goal of this proposal is to develop novel HH-SECTR technology for visualizing and quantifying diagnostic disease features in prematurely born infant retinopathy of prematurity (ROP) patients that lead to more informed clinical decision making. Providing depth-resolved vascular information has not been adequately investigated for its diagnostic potential. Furthermore, we seek to identify disease features not currently accessible by standard examination methods to better inform clinical decisions.
The PROTECT2 pilot study is a single cohort prospective study to gather pilot data and finalize operational details of the main study. The PROTECT2 main study is a prospective randomized controlled multi-center three group clinical trial. The primary endpoint is the percentage of participants in each study group obtaining a qualified eye examination within 12 months of their enrollment in the study.
The goal of this randomized, parallel-group, controlled trial is to compare methods of enhancing linkage-to-care for participants in the Village Integrated Eye Worker II (VIEW II) trial who are referred to the eye hospital following eye disease screening. Participants who are referred to the hospital at an eye screening visit will be randomized to three different linkage-to-care interventions: (1) text message reminders, (2) reminders from community health workers, or (3) no intervention. The primary outcome of the trial will be whether or not the participant presented to the eye hospital for a referral visit by 21 days following screening.
The purpose of this research study is to evaluate the efficacy, patient preference, and utility of a novel eye shield that utilizes a different adhesive mechanism in comparison to the current standard of care. The aims are to see if this product could be incorporated into postoperative care in the future to improve patient satisfaction and compliance. The study will involve 20 patients during the postoperative timeframe after cataract extraction and intraocular lens placement (CEIOL). These patients will be chosen from the clinic of Dr. Marc Toeteberg who will plan to have both eye surgeries done within 3 months of each other. These patients will be randomized to either control or intervention group. Intervention group will receive our novel eye shield prototype, while control group will receive an Alcon plastic eye shield. Both groups will receive the eye shields after surgery and will be sent home with these eye shields with normal postoperative care directions. Patient will be directed to wear eye shields for 24 hours then at night for first 2 weeks after surgery, while adhering to postoperative eye drops regimen. After successfully healing and passing the postoperative timeframe for the first eye we will proceed to the second arm of the study. Approximately 1-2 months after healing from the first surgery, patient will be scheduled for cataract surgery on the other eye, as is standard of care. After surgery on the second eye the patient will be given the other eye shield than what they received after the first surgery (control groups will receive the novel eye shield and experimental groups will receive the control eye shield). They will proceed to follow identical postoperative protocols after the second surgery. A short quantitative and qualitative questionnaire directly comparing the two eye shield experiences will be provided at the 1 month follow-up after the eye surgery.
The study is collecting data along with other academic institutions regarding the accuracy of ocular ultrasound in diagnosing retinal detachment.
Amblyopia ("lazy eye") and strabismus (misaligned eyes) are medical eye conditions that combine as the leading causes of preventable vision loss in children. They are irreversible if not detected and corrected by the age of seven, however half of all cases are missed because the conditions do not always manifest themselves and pediatricians are unable to reliably detect the conditions. The current health care system badly needs an accurate and effective approach toward detecting amblyopia and strabismus in preschool children. The study will be conducted in busy, ethnically and racially diverse primary care sites operated by the Kaiser Permanente system and compare the outcomes of testing with a Pediatric Vision Scanner with outcomes the current standard of care.
To compare the efficacy of twice-daily topical bromfenac (Xibrom) ophthalmic solution alone versus twice-daily topical Xibrom with prednisolone acetate 1% three-times daily on visual acuity and OCT measurements.
The goal of this prospective crossover simulation study is to evaluate the accuracy and usability of a 3D camera weight estimation system during simulated emergency care in adult simulated patients, when used by emergency physicians. The main questions the study aims to answer are: * to evaluate the accuracy of 3D camera weight estimation during simulated emergency care, when compared with standard methods * to evaluate the usability of 3D camera weight estimation during emergency care, when compared with standard methods * to evaluate the inter-user reliability of 3D camera weight estimates Volunteers for simulated patients will be required to have anthropometric measurements, a DXA scan, and 3D camera weight estimates. Physician volunteers will need to participate in simulated emergency scenarios during which weight-based therapy must be administered. There will be no interventions.
Participants will be recruited by performing chart reviews of patients to be seen at University of Texas Medical Branch at Galveston Ophthalmology and Optometry Clinic. A sample size of at least 30 patients is needed (60 eyes). Patients aged 55 and higher will be further evaluated to meet the inclusion criteria. Patients meeting inclusion criteria will be provided with informed consent to participate in the study before their office visit. Patients will receive a consent briefing then asked to sign and date the informed consent form. Participants will then be randomized to undergo an eye exam and refractive exam with noise cancelling Bluetooth headphones for one eye and without for the other eye. Participants will fill out a written survey asking them to rate the quality of the eye exam with and without headphones. Primary aim: Assess the quality improvement of Ophthalmic exam in geriatric patients with hearing loss with use of noise cancelling headphones with Bluetooth feature. Secondary aims: 1)Compare the response to the standardized questions with and without Bluetooth noise cancelling headphones to determine their effectiveness in conducting Ophthalmic refractive exam. 2) Explore the ease of conducting refractive exam as reported by provider.
Study is a randomized clinical trial evaluating the efficacy of novel mobile application technologies (including Seeing AI, Aira, and Supervision+) to improve quality of life in older adults with low vision by expanding community access and providing assistance with activities of daily living. Aira provides real-time remote personal assistance through a sighted Aira agent supplying direct feedback to assist with visual tasks. Seeing AI provides optical character recognition allowing any text to be read aloud, color identification, bar code reading, scene description, and facial recognition based on stored photos. Supervision + allows one to use the phone as a magnifier, providing magnification and contrast enhancement using the camera of the mobile phone. This study seeks to understand the potential of these technologies to improve daily activities, community participation, independence, and self-sufficiency in this group by examining a technological approach, which has not yet undergone rigorous investigation in a diverse population of older adults with visual impairment. Project objectives are to evaluate mobile applications in a wide range of visual disability, categorized into three groups: (1) mild to moderate visual acuity loss, (2) severe to profound visual acuity loss, and (3) legal blindness secondary to visual field loss. Participants are randomized to one of three intervention groups: (1) Supervision+ application, (2) Aira application, or (3) Seeing AI application for a period of 6 months. For the Aira intervention group, participants will be assigned either with 'restricted' access (current open access areas plus 30 minutes/month anywhere), or 'unrestricted' access (700 minutes), for a period of 3 months with a 3 month cross-over period. Participants may elect to continue the study for an additional 3 months during which time they have access to all 3 study mobile applications. Outcome measures include assessment of changes at three, six and nine months post-intervention for: visual ability, health state (including depression), self-efficacy, loneliness, life space, distances travelled from the home, and types of services obtained.
