Filter by:This is a prospective Multi-Center Observational Study to assess the reliability and validity of the Multi-Luminance Y-Mobility Test (MLYMT) and Multi-Luminance Shape Discrimination Study (MLSDT) Main Outcome Measures: (i) Performance scores in normal and severely visually impaired subjects with a clinical diagnosis of retinitis pigmentosa (RP) on MLYMT and MLSDT at multiple luminance levels and (ii) reliability and content validity of MLYMT and MLSDT.
The purpose of the study is to evaluate the safety and efficacy of a single intravitreal injection of virally-carried Multi-Characteristic Opsin (MCO-010).
The aim of this study is to determine if umbilical cord Wharton's jelly derived mesenchymal stem cells implanted in sub-tenon space have beneficial effects on visual functions in retinitis pigmentosa patients by reactivating the degenerated photoreceptors in dormant phase.
The aim of this study is to evaluate the efficacy and safety of oral minocycline (100mg/d), administered for 6 months, for the treatment of patients with retinitis pigments(RP).
The purpose of this research is the evaluation of a combined coaxial optical coherence tomography (OCT) system to image retina/choroid and to evaluate if post processing of the data can give us insights into property of the tissue imaged.
To evaluate the efficacy and safety of intravitreal ranibizumab (IVR) injection in the treatment of non-leaking macular cysts in patients with retinal dystrophy. Material and Methods: Design - Prospective, nonrandomized, nonblinded, clinical trial. Participants - Patients >18 years diagnosed with retinal dystrophies and non-leaking macular cysts between Jan 2015 and July 2018 in 1 center. Methods - Phase 1: Patients with best corrected visual acuity (BCVA) < 0.5 will receive carbonic anhydrase inhibitors (CAI) [oral acetazolamide 500mg/day or topical brinzolamide twice daily] and followed up for three months. Phase 2: Patients who do not show an adequate response with CAI will receive three 0.5mg IVR injection at monthly intervals. Outcome - 1) Significant reduction (> 10%) of the central macular thickness (CMT), 2) Improvement (> 1 line) in BCVA 3) Presence of any complication.
To develop comprehensive genetic maps of inherited retinal diseases in Korean - Establishment of comprehensive genetic database in Koreans with inherited retinal diseases including frequently mutated genes, genotype-phenotype correlations, and visual prognosis."
The goal of this study is to examine the ability of optical head‐mounted display technology to enlarge the visual field of patients with severe visual field loss due to retinal dystrophy and to improve mobility and patient‐reported outcomes.
This study is a longer-term follow-up study for patients who have been administered AAV2/5-OPTIRPE65 in the Phase I/II, open label, non-randomised, two-centre, dose escalation trial in adults and children with retinal dystrophy associated with defects in RPE65.
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.
