5 Clinical Trials for Various Conditions
Safety and efficacy of 0.75% Phentolamine Ophthalmic Solution to improve mesopic low contrast visual acuity in subjects with post-refractive surgery visual disturbances.
Prospective survey study of patients who previously underwent cataract surgery with the Alcon PanOptix or PanOptix Toric intraocular lens in both eyes.
Our goal is to study the relationship between intraocular pressure during robotic prostatectomy surgery and visual deficiencies/vision loss after surgery. We believe the risk of vision loss from this surgery to be due to positioning during the operation, as well as abdominal carbon dioxide insufflation. As robotic procedures are gaining in popularity, we should determine whether they are subjecting this patient population, and perhaps more likely the patient with a preoperative diagnosis of glaucoma, to an increased likelihood of postoperative visual disturbance.If our hypothesis that intraocular pressure is increased in these patients is confirmed, future studies will assess therapeutic modalities to maintain the IOP near baseline.
The prospective pilot study will address the critical need for more precise characterizations of the acute visual effects of the drug psilocybin by measuring the impact of acute psilocybin intoxication on a perceptual task known as visual surround suppression, compared to an active placebo control.
This study aims to provide novel information on the feasibility of yoga interventions for secondary symptoms related to severe vision loss, such as sleep disturbances, negative mood states, fall risk and balance. This information will be important for determining safe, cost-effective and reliable practices for the benefits of yoga as an alternative means for improved health and well-being. A yoga intervention that is integrative and evidence-based will benefit the blind population through effective treatments and prevention of secondary symptoms as well as serve to inform rehabilitation specialists, educators, and clinicians in the future.
