We list hundreds of Clinical Trials about "Vision" on BioPortfolio. We draw our references from global clinical trials data listed on ClinicalTrials.gov and refresh our database daily.
We have published hundreds of Vision news stories on BioPortfolio along with dozens of Vision Clinical Trials and PubMed Articles about Vision for you to read. In addition to the medical data, news and clinical trials, BioPortfolio also has a large collection of Vision Companies in our database. You can also find out about relevant Vision Drugs and Medications on this site too.
To evaluate health related quality of life (HRQoL) of low-vision patients and their care givers undergoing low-vision rehabilitation program (LVRP).
This study will determine if the interdisciplinary team low vision rehabilitation program is more effective than basic low vision care provided by an optometrist working alone in improving visual reading ability in veterans with macular diseases and best corrected visual acuity of 20/50 to 20/100.
The purpose of this study is to see if Stendra causes any changes in vision, eye pressure, pupil dilation, and color vision in healthy males.
The primary purpose of this research study is to evaluate the effectiveness of a new outpatient low vision rehabilitation program that is targeted to serve legally blind veterans with central vision loss. The hypothesis is that veterans in the treatment group will self-report less difficulty performing daily activities than veterans in the control group who are on a waiting list for VA low vision or blind rehabilitation programs.
1. Purpose a. Examination on Efficacy of Retina Projection System 2. Patients a. Low vision patients 3. Methods 1. Vision aids - Retina Projection System - Face-mounted video display as control 2. Comparison of Reading Speeds with both vision aids
Providing Access to the Visual Environment is a pediatric low vision grant which has the ability to provide comprehensive, interdisciplinary low vision rehabilitation services to every child in Tennessee with a vision impairment. Children, ages 3-21, with best-corrected vision of 20/50 or worse in the better seeing eye are prescribed optical devices to improve their visual functioning and trained to use the devices.
To identify vision-screening tests that can accurately predict those three- and four-year old preschoolers who would benefit from a comprehensive vision examination because of signs of amblyopia, strabismus, and/or significant refractive error.
The purpose of this research project is to develop a vision surveillance system, in order of understanding the vision health status of children and adolescents in Taiwan.
Retrograde intrarenal surgery (RIRS) has been considered as the first-line choice for the management of ＜20mm kidney stones. Insertion of a ureteral access sheath (UAS) before RIRS surgery is currently accepted as an effective method to improve the effectiveness of surgery, but can be accompanied by serious complications. In long-term clinical practice， the investigators has found that many ureteral injuries occur during UAS insertion of the ureter from ureteral orifice. An...
This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation...
The purpose of this research is to collect preliminary data in preparation for conducting a randomized clinical trial to determine the relative effectiveness of vision rehabilitation in improving overall visual ability (primary aim) and reducing depression (secondary aim) in patients receiving anti-VEGF therapy for neovascular age-related macular degeneratioin integrated over time.
There are indications in the literature that binocular vision disorders may occur after cataract and corneal refractive surgery. It is not clear whether these problems are new or represent decompensation of previously existing conditions. However, the following significant study limitations exist in the current literature: 1) lack of attention to non-strabismic binocular vision disorders, 2) incomplete binocular vision assessment, 3) a validated symptom survey was not used, 4) ...
The purpose of this study is to demonstrate that the Centurion® Vision System used with the 45° Balanced Tip will result in less Cumulative Dissipated Energy (CDE) than the lnfiniti® Vision System used with the 45° Mini-Flared Kelman (MFK) tip during cataract extraction surgery via phacoemulsification of cataract grades NII- NIV [Lens opacities classification system II (LOCSII)].
We wish to evaluate a potential training program for patients with glaucoma, to become more efficient users of prescribed low vision devices for distance and near vision tasks. We hypothesize that the devices will improve efficiency. Prescribed devices will include a stand magnifier, a handheld magnifier, spectacle magnifiers for near vision, and a handheld monocular (telescope) and a bioptic telescope (spectacle-mounted telescope) for distance vision. The success of being able...
The purpose of this protocol is to determine if the Welch-Allyn Spot Vision Screener (SPOT) is effective at detecting various risk factors for poor vision in developmentally delayed children. These children have a higher percentage of vision disorders than the average population. The SPOT screen itself takes about six seconds to complete. It produces a photograph of the eye and a print out with amount of hyperopia, myopia, astigmatism and pupil size. The subject will have three...
The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes implanted under a corneal flap or within a small-incision pocket.
Prospective Internet-Registry, Postmarketing-Surveillance, Registration and Follow-up of patients after Multi-Link VISION™ - Stent Implantation
The objective of this study is to evaluate the safety and effectiveness of the Raindrop Near Vision Inlay implanted in bilateral pseudophakes with presbyopia for improvement of near and intermediate vision. The ReVision Optics corneal inlay is a 2.0-mm, 30-micron inlay made of a hydrogel material, implanted under a lasik flap. Subjects must require reading add from +1.50 D to +2.50 D. Subjects must have a preoperative manifest refraction spherical equivalent of -0.50 to +1.00 D...
Retinitis pigmentosa (RP) patients experience a slowly progressive, unpredictable loss of vision which eventually leads to bare or no light perception, posing a continuous threat to patients' independence. Negative psychological states such as distress, sleepiness, anxiety and depression are common in RP patients due to the nature of this chronic, disabling disease. Psychophysical vision measures are more variable in legally blind RP subjects than in normally sighted individual...
The objective of this study is to evaluate the Raindrop® Near Vision Inlay for the improvement of near vision in presbyopes treated with low dose, short duration Mitomycin C (MMC) during surgery and an extended low dose steroid regimen after surgery.
The primary objective of this study is to evaluate the distance, intermediate and near visual performance of Clerio designed single vision and Clerio designed LIRIC modified bifocal lenses (+2.00D add) compared to commercially available single vision and multifocal lenses.
This study seeks to compare colonoscopy results between a standard method and one using a distal scope attachment (Endocuff Vision).
With the aging of the population, the prevalence of age-related macular degeneration (AMD) eye disease has resulted in a large number of people suffering from central vision loss. In fact, the most prevalent cause of blindness among veterans is AMD. Since the number of elderly veterans is expected to double in the next 10 years, loss of vision due to AMD is also expected to proportionally and considerably escalate. People with impaired vision have difficulty with daily activ...
The purpose of this study is to determine whether EV06 is safe and effective in improving distance-corrected near vision in people who have presbyopia.
Patients who underwent presbyopic correction with bilateral bifocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require near vision acuity (NV), (ie. book reading). However, it is known that light intensity and temperature has a great impact on near vision capacity. Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and tempera...
