Active clinical trials for "Diplopia"

The transient diplopias (TD) is defined by a short diplopia. Their etiology may be ophthalmological, neurological non-ischemic or of ischemic origin. The difficulty is to recognize an ischemic mechanism which imposes emergency cares. A clinical score could help the clinician to recognize the etiology of the TD .

PURPOSE: The purpose of this study is to quantitatively assess the efficacy of monovision correction in the treatment of acquired small angle binocular diplopia in adult patients. METHOD: Twenty patients with symptomatic diplopia were enrolled in a prospective treatment trial. All had stable deviations of 10 prism diopters or less for over three months. Each received monovision spectacles and/ or contact lenses with distance correction in the dominant eye. Half received a +3.00 diopter (D) add and the others received +2.50 D. The validated and standardized Diplopia Questionnaire and Amblyopia and Strabismus Questionnaire (ASQE) were used to quantify the efficacy of monovision correction for diplopia by measuring the functional impact on vision-specific quality of life.

Hypothesis: Polycaprolactone / Tricalcium Phosphate Orbital (PCL / TCP) Implant is as effective in the reconstruction of the Orbital walls as Titanium Mesh implant. In this study we will be conducting a randomised trial to compare implants made of 2 materials for Orbital reconstruction Polycaprolactone / Tricalcium Phosphate (PCL / TCP) Titanium Patients to be recruited : 80 randomised equally into the 2 groups age range: 21 - 70 includes orbital wall defects from trauma, after osteotomies excludes patients with Diabetes Mellitus, known allergies to polycaprolactone & its analogues, know allergies to Tricalcium Phosphate & its analogues, infections generalised & around the orbital region Trial Duration: April 2010 - March 2015 Follow up: postoperative 1 week, 1 month, 3 months, 6 months, and 12 months Computer Tomographic (CT) scan of Orbits immediate postoperative and at 12 months appointment

In this research study we want to test how people understand a visual scene when the same image is presented to both the eyes, but portions of these images are altered in terms of contrast, depth or in some cases motion.

IRM-DU is a prospective observational single center study conducted in an emergency department to evaluate the impact of a MRI scanner exclusively dedicated to emergency in the clinical management of patients presenting with dizziness or diplopia. The study will compare 2 strategies : after and before availability of a MRI scanner dedicated to emergency. The primary endpoint is the proportion of patients with a diagnosis of stroke confirmed by imaging (MRI or Computed tomography (CT)) in the group "before implementation of the emergency MRI scanner" and the group "after implementation of the emergency MRI scanner". The hypothesis is that the availability of a MRI scanner dedicated to emergency will improve the diagnosis of stroke in patients presenting with dizziness or diplopia, and will reduce Emergency Department stay, hospital stay and hospitalisation costs.
