Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Aged 18 years or older
* Either gender
* A confirmed history of outer retinal degenerative disease such as retinitis pigmentosa or choroideremia
* Remaining visual acuity of bare light perception or less in both eyes
* Functional inner retina (ganglion cells and optic nerve), as shown by the ability to perceive light and/or a measurable corneal electrically evoked visual response
* A history of at least 10 years of useful form vision in the worse seeing eye
* Must be willing and able to comply with the testing and follow-up protocol demands (preferably residing within 1.5 hours of the investigational site)
Minimum age
18 Years
Maximum age
80 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Optic nerve disease (history of glaucoma of more than 1 month, or history of any other optic neuropathy)
* Diseases of the inner retina including, but not limited to, central retinal artery or vein occlusion (CRAO, CRVO), end stage diabetic retinopathy, retinal detachment, traumatic retinal damage, infectious retinal disease, inflammatory retinal disease.
* Inability to visualise the retina due to corneal or other ocular media opacities (corneal degenerations, dense cataracts, trauma, lid malpositions)
* Any ocular condition that predisposes the subject to rubbing their eyes
* Cognitive deficiencies, including dementia or progressive neurological disease
* Psychiatric disorders, including depression, as diagnosed by a qualified psychologist
* Deafness or significant hearing loss
* Inability to speak or understand English
* Pregnancy
* Presence of a cochlear implant
* Subject enrolled in another investigational drug or device trial for the treatment of their ocular condition
* Poor general health, which would exclude them from obtaining a general anaesthetic
* Unrealistic expectations of the bionic eye device
