Active clinical trials for "Vision Disorders"

The purpose of this study is to evaluate the efficacy safety and tolerability of ultevursen administered via intravitreal injection (IVT) in subjects with Retinitis Pigmentosa (RP) due to mutations in exon 13 of the USH2A gene.

This study evaluates the safety, tolerability and efficacy of QR-1123 injection in the eye (intravitreal; IVT) injections (one eye/unilateral) in subjects receiving a single dose or repeat doses. Single injections will be assessed in an open label way, and repeat injections will be assessed in a double-masked, randomized, sham-controlled fashion.

This pilot study will integrate multi-sensor fusion techniques (software) to effectively combine information obtained from the newly embedded infrared, ultrasound, and stereo-camera-based sensor systems (hardware) that are implemented into the VIS4ION platform. The core of this technology is based on 4 components: (1) a wearable vest with several distinct range and image sensors embedded. These sensors extract pertinent information about obstacles and the environment, which are conveyed to (2) a haptic interface (belt) that communicates this spatial information to the end-user in real-time via an intuitive, ergonomic and personalized vibrotactile re-display along the torso. (3) A smartphone serves as a connectivity gateway and coordinates the core components through WiFi, bluetooth, and/or 4G LTE, (4) a headset that contains both binaural, open-ear, bone conduction speakers (leaving the ear canal patent for ambient sounds) and a microphone for oral communication-based voice recognition during use of a virtual personal assistant (VPA). Blindfolded-sighted, and blind subjects in a real-world, combined obstacle avoidance / navigation task will serve as an independent measure of overall improvements in the system as well as a roadmap for future avenues to enhance performance. Further, a prospective, randomized crossover, controlled, non-blinded phase will be conducted in Thailand as part of this study to compare and evaluate effectiveness of the wearable vest for increasing navigation and quality of life.

The purpose of this study is to test whether a binocular treatment can improve vision and motor function in young children with amblyopia. The proposed treatment is an animation series that has been modified so that different characters in the animation are presented to each eye. The contrast of the images shown to the amblyopic eye is higher than the contrast of the images shown to the fellow eye. The aim of the treatment is to promote co-operation between the two eyes and improve visual and motor outcomes. We will compare the benefits of this binocular treatment to patching, whereby the better eye is occluded with an eye patch for two hours per day to force the usage of the weaker eye. We hypothesize that the binocular treatment will improve vision and motor outcomes in young children with amblyopia, and that these improvements will be superior to any effects of patching.

The purpose of this study is to evaluate the safety, tolerability and efficacy of a single escalating doses of EDIT-101 administered via subretinal injection in participants with LCA10 caused by a homozygous or compound heterozygous mutation involving c.2991+1655A>G in intron 26 of the CEP290 gene ("LCA10-IVS26").

The purpose of this double-masked, randomized, controlled, multiple-dose study is to evaluate the efficacy, safety, tolerability and systemic exposure of sepofarsen (QR-110) administered via intravitreal injection in subjects with Leber's Congenital Amaurosis (LCA) due to the CEP290 p.Cys998X mutation after 24 months of treatment

The study will compare the safety of ophthalmic bevacizumab in vials versus pre-filled syringes in subjects diagnosed with a retinal condition that would benefit from treatment with intravitreal injection of bevacizumab, including: exudative age-related macular degeneration, diabetic macular edema, or branch retinal vein occlusion.

To assess repeatability of electroretinogram and visual evoked potential in clinical practice

This study is exploratory and examines whether the best-corrected visual acuities (BCVA's) from trial frames created with the refraction results obtained from a novel handheld optical device yields results similar to the ophthalmic refraction obtained from an autorefractor in healthy volunteers age stratum of 18 through 65 years.

Patients may experience metamorphopsia, or image distortion, after having vitrectomy to repair their rhegmatogenous retinal detachments especially those with a detached macula. Retinal displacement, as measured on autofluorescence photography, likely contributes to this distortion. It is thought that the retina slips inferiorly due to the residual subretinal fluid shifting as the patient transitions from the supine position intraoperatively to the sitting up position in the immediate postoperative period. By having the patient immediate position facedown or according to the retinal break, the risk of slippage is theoretically decreased.
