In the home-based vision orthoptic therapy (HBVOT) group, patients were trained to do the pencil push-ups procedure 15 minutes per day, five days a week. In the office-based vision orthoptic therapy (OBVOT) group, 60 minutes of orthoptic therap...
Prospective, open-labeled, randomized, controlled, multicenter study at two clinical investigative sites in Tucson, Arizona. The subjects will undergo intraocular pressure measurement with the CATS tonometer prism and the Goldmann applanation tonometer prism (GAT). Of the 150 eyes, at least 10 highly astigmatic eyes (>3 D of corneal astigmatism) each in the low, medium and high IOP ranges shall have the same clinical testing and analysis of results, with the analysis kep...
To determine whether the preoperative use of prisms in eyeglasses can improve the outcome of surgery for acquired esotropia, a type of strabismus. To determine whether patients who respond to prism adaptation by developing a new stable angle of -deviation have a better surgical result than do patients who do not respond to prism adaptation. To determine whether patients who respond to prism adaptation are more accurately corrected by operating for the prism-adapted angl...
Background: After a stroke, the balance between the two halves of the brain can be lost. This may cause people to lose the ability to perceive a side of space. This is called neglect. Having people wear prism glasses (called PA) can reduce neglect symptoms. Researchers want to find out more about how PA, and whether it restores the balance in the brain. Objective: To learn how prism adaption temporarily changes vision and connections in the brain. Eligibility: ...
The focus of the study is to evaluate the expanded version of PRISM 1.0 for a broad array of seniors with different needs and circumstances. The aims of the study are to: 1) obtain information on perceptions of the usefulness and usability of PRISM 2.0 and interface design issues; 2) examine the impact of access to PRISM 2.0 on social connectivity, engagement, social support, and perceived loneliness; 3) examine the impact of access to PRISM 2.0 on perceived isolation, well-bei...
The primary goal of this study is to evaluate the PRogram In Support of Moms (PRISM) that aims to improve women's access to and participation in perinatal depression treatment and thereby improve depression outcomes
The objective of this short-term, pilot randomized trial comparing spectacles with relieving prism to spectacles without prism is to determine whether to proceed to a full-scale, longer-term randomized trial. This decision will be based primarily on assessing the initial (8-week) response to prism by comparing treatment groups on the following outcomes: - Mean distance intermittent exotropia (IXT) control score (the mean of 3 control scores) (primary outcome) ...
The purpose is to validate the PRISM-5-Op as a measurement of prescription opioid substance use disorder.
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.
The purpose of this study is to investigate the effect of virtual prism adaptation therapy on hemispatial neglect in chronic stroke patients. This study is the randomized, double-blind, sham-controlled, cross-over design. Total 10 patients will be allocated randomly to either real virtual prism adaptation therapy or sham therapy with the wash-out period of more than 2 weeks. Two sessions (20min/session) per day, for 5days (total 10 sessions) will be provided. Behavioral outcome...
The purpose of this research study is to examine the effects of prism adaptation or bromocriptine treatment on two visual-spatial recovery components. After a stroke, an "internal GPS", locating where objects or people lie in a particular area of space, may be impaired. Alternately, a stroke may impair precise visual-spatial hand and body aiming movements. The research team wishes to discover whether using prism goggles, or taking a medication (bromocriptine) affects visual-sp...
The present study aims to compare the relative therapeutic efficacy of prism adaptation therapy combined with real versus sham tDCS. The investigators will test the hypothesis that the magnitude and duration of neglect improvement will be increased when prism therapy is combined with real tDCS compared to sham tDCS. A second objective is to test whether individual differences in baseline clinical or brain imaging measures can predict: 1) neglect severity or 2) inter-individual...
Parenting a child with cancer is highly stressful. The investigators have designed a promising parent-centered intervention to bolster parent resilience and reduce stress and distress. This study will test 2 formats of the intervention (individual or group-based) and compare them to usual care.
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 aim of this study is to evaluate the effect of ENDOCUFF VISION® (caps with soft, about 1 cm long lateral feet of rubber ("Endocuff") to flatten the colon folds) on ADR in a real-life setting (general practices) and in a homogenous patient collective (screening colonoscopies only). It is a prospective randomized multi centric study, with participation of at least 10 study sites (private practice). The study is an inverstigator-initiated trial (IIT). Depending on the...
Spatial neglect is a common attention disorder after right hemisphere stroke and is associated with decreased independence and quality of life. Despite its high prevalence in the stroke population, there is currently no standard of care for the treatment of neglect. Prism adaptation (PA) is a promising rehabilitation technique, however incorporation into clinical care has been limited likely due to the lack of standardized procedures. The investigators have developed a computer...

Multisite Randomized Controlled Trial (RCT) testing the efficacy of the Promoting Resilience in Stress Management (PRISM) intervention among Adolescents and Young Adults receiving hematopoietic cell transplantation for hematology malignancy.
Vision loss can result in feelings of frustration, helplessness, anxiety, depression, and anger, which compromise a person's activities of everyday living. While emotional distress may resolve in some persons without intervention, unmanaged and persistent distress places the person at risk for continued decrements in health status and the potential development of more severe conditions (i.e., depression, poor health outcomes). Persons with low vision will be recruited and rando...
