Retinitis pigmentosa (RP) is a progressive degenerative disease of the retina, which often leads to blindness. 1 in 4000 people in the UK are affected by RP yet there is no established therapy for treating or delaying its progression. Transcorneal electrical stimulation (TES) has garnered attention as a possible therapeutic option for RP. Research has shown that TES improves retinal cell viability and visual function. An initial pilot study of TES on 24 participants with RP demonstrated that it was safe and improved vision. This study aims to confirm the safety of the new CE-approved Okustim device and to further characterise the benefits of TES on a larger scale. 12 participants will be enrolled for 1 year across two sites in the UK - the Oxford Eye Hospital and London Moorfields Eye Hospital. Recruited participants will undergo weekly TES of 1 eye for 30 minutes for a period of 6 months. This will be followed by a further 6 months of observation without stimulation giving a total participation time of 1 year. Participants will be assessed at 3, 6, 9 and 12 months after their initial baseline visit by clinical examination, investigations and questionnaires. Participants should have a diagnosis of RP and be capable of giving consent. Participants, or a carer, should have sufficient motor skills to attach the device themselves. As this study seeks to ascertain the impact of TES on RP, participants with other eye diseases (e.g. diabetic retinopathy) cannot be included in the study.
The purpose of this study is to determine the long-term effects of transcorneal electrostimulation (TcES) in patients with retinitis pigmentosa (RP). In a prior study (NCT00804102) the results of short-term stimulation showed a positive effect on the visual field and other parameters. In this study, the patients will be stimulated with either 0%, 150% or 200% of the individually determined phosphene threshold.
The purpose of this study is to expand the safety assessment of repeated applications of an electrical current from a DTL-like electrode in patients with RP.
Microcurrent stimulation thereapy improves retinal efficiency and may restore and/or improve retinal function.
Retinitis Pigmentosa (RP) patients are interested in trying alternative therapies to attempt to slow, halt or reverse the retinal disease process, and claim success with some approaches such as acupuncture, but this potential treatment has not been put to the test of objective, rigorous scientific study conducted in western society. In this pilot study, the investigators aim to evaluate an acupuncture treatment tailored to the RP population for its feasibility to improve visual function, specifically visual field and dark adaptation. The study results may provide a basis for eye care providers' recommendations to RP patients regarding whether to consider acupuncture as a potential treatment modality. If our hypotheses regarding improvements in vision beyond typical test variability are supported, our future research goals include the conduct of a larger clinical trial with involving randomization and a placebo control for acupuncture in RP.
This study will be an initial proof of concept study, to evaluate safety and efficacy of a prototype suprachoroidal retinal implant
The purpose of this study is to evaluate the short-term safety and efficacy of a single intravitreal injection of autologous bone marrow stem cells in patients with retinitis pigmentosa.
The purpose of this study is: - To evaluate whether 7-day treatment with oral QLT091001 can improve visual function in RP subjects with an autosomal dominant mutation in RPE65. - To evaluate duration of visual function improvement (if observed) in RP subjects with an autosomal dominant mutation in RPE65 after 7-day treatment with oral QLT091001. - To evaluate the safety of oral QLT091001 administered once daily for 7 days in RP subjects with an autosomal dominant mutation in RPE65.
The purpose of this study is to determine the feasibility and safety of adult human bone marrow-derived mesenchymal stem cells by intravitreal injection in patients with retinitis pigmentosa.
