Filter by:This study evaluates the safety and effectiveness of the Intelligent Retinal Implants System (IRIS V2). Blind patient suffering from Retinitis Pigmentosa, Cone Rod Dystrophy, or Choroideremia are implanted with an Intelligent Retinal Implant Systeme. All subjects undergo ophthalmological examinations in predefined intervals after implantation. Ophthalmological examinations include funduscopy, slit lamp examination and OCT. All adverse events are recorded and analyzed. Efficacy is measured using functional vision and visual function tests before and after implantation as well as with the system on and system off.
This protocol is a phase 1 clinical study to assess the safety and pharmacokinetics of ALK-001 in healthy volunteers. Please contact trials@alkeus.com for any questions.
Vision testing is a fundamental part of every optometry and ophthalmology assessment. Traditional vision testing charts are not able to measure vision below a certain level. Vision in this range is classified as counting fingers (CF), hand movements (HM) and light perception (LP). These measures are not very accurate or easily quantifiable. They are also poorly understood in terms of impact on quality of life. This study aims to assess new methods for measuring the vision of patients with very low vision.

Using an adaptive optics imaging device, retinal structures are observed in healthy and diseased subjects.
The purpose of the study is to assess the safety and efficacy of the active substance rAAV-2/4.hRPE65 in patients with Leber Congenital Amaurosis or Congenital severe early-onset retinal degeneration associated with RPE65 mutation.
Retinal dystrophies are responsible for numerous cases of blindness, and there are no therapeutic possibilities today. Gene therapy is efficient in a dog model concerning dystrophy linked to a mutation of the rpe65 gene. If such a therapy is to be considered for humans, it is urgent to select, at a national level, patients suffering from dystrophy linked to a mutation of the rpe65 gene. The systematic correlation of phenotype/genotype is an anatomical-functional approach, but it also identifies patients who may be potentially included in a future gene therapy study. Indeed, identification of people with a mutation of rpe65 is still insufficient in France (compared to other European countries) because of a lack of systemic genotyping of retinal dystrophy.
