Active clinical trials for "Vision, Low"

The aim of our study is to examine the effects of eight sessions of online social skills training given to visually impaired adolescents on social skills, self-efficacy, social phobia and social integration. Forty visually impaired adolescents between the ages of 13 and 19 participated in the study. Participants were divided into control and training groups. 20 adolescents were included in the education program. All participants included in the study were evaluated using the Sociodemographic Information Form, Social Skills Assessment Scale for Children, General Self-Efficacy Scale, Child and Adolescent Social Phobia Scale, and Social Integration Questionnaire.

The purpose of this study is to compare the effectiveness of intravitreal bevacizumab injection (IVBI) with respect to simple observation in patients with subfoveal choroidal neovascularisation (CNV) secondary to age-related macular degeneration (AMD) presenting at baseline with best corrected visual acuity (BCVA) less than 20/200.

This study was designed to confirm the efficacy and safety of ranibizumab (0.5 mg) as adjunctive therapy when added to laser photocoagulation and/or as monotherapy in Asian patients with visual impairment due to Diabetic Macular Edema (DME).

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.

This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant after 6 months of treatment. In the study arm Ranibizumab will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

This clinical trial is designed to compare ranibizumab in comparison with Dexamethasone implant® after 6 months of treatment. In the study arm Lucentis will be given monthly in a pro re nata scheme whereas the comparator Dexamethasone implant is given once at Month 0 with sham injections PRN afterwards.

The primary objective of the study was to investigate current criteria driving re-treatment in patients affected by Choroidal Neovascularization (CNV) secondary to Pathologic Myopia (PM) and experiencing a relapse of the disease after the first administration of ranibizumab.

Non-invasive brain stimulation can increase cortical excitability in the visual system, but it is not known if this is of clinical value. The investigators now assessed if repetitive, transcranial alternating current stimulation (rtACS) can improve visual field size in patients with optic nerve damage. The investigators hypothesized that rtACS would improve visual functions with the defective visual field sectors of the visual field (primary outcome measure).

The purpose of the current study was to compare the visual performance after bilateral implantation of the Panoptix IOL , or the AT LISA IOL or Tecnis Symfony IOL . The focus was on intermediate vision, defocus curves, and contrast sensitivity.

Over 1 million people in the UK suffer from untreatable visual impairment, many of them elderly. The major complaint of visually impaired people is their inability to carry out simple tasks, especially those involving reading. It is known that this activity limitation is a major cause of depression in an older population, and it is reflected in reduced quality of life. Low vision clinics, mostly based within hospital ophthalmology departments, dispense optical magnifiers to allow patients to carry out these tasks again, but these devices do have limitations (unusual posture, short working distance, monocular viewing). Although electronic magnifiers have been around since the 1960s, they were initially very large and expensive. Recent advances in technology have brought about an explosion in the number and range of portable and moderately-priced aids, which can be used binocularly, in a natural working position: these are currently not available through the NHS. Evidence is needed as to whether these portable hand-held electronic magnifiers could offer a significant benefit to the majority of patients, and therefore whether they should be routinely dispensed in low vision clinics. The proposed study is a two-arm randomised crossover trial with existing users of optical magnifiers being assigned to use a hand-held electronic magnifier in addition to their existing devices for 2 months. Reading and task performance will be measured with the aid, and compared to the performance with optical aids, and the patient will be asked to report on the comparisons between the aids.
