Retinal implant

Retinal implant is a biomedical intervention that involves the implantation of a device designed to partially restore lost vision or amplify existing vision in individuals suffering from certain types of eye diseases and conditions. The technology is primarily aimed at patients with severe retinitis pigmentosa and other degenerative retinal diseases.

Overview[edit | edit source]

A retinal implant, or bionic eye, is a surgical treatment for certain kinds of inherited retinal diseases. The device works by converting images into electrical impulses that can be interpreted by the brain. The implant is placed in and around the eye, where it can stimulate the remaining healthy cells in the retina.

Types of Retinal Implants[edit | edit source]

There are two main types of retinal implants: epiretinal, placed on the surface of the retina, and subretinal, placed behind the retina.

Epiretinal Implants[edit | edit source]

Epiretinal implants are placed on the surface of the retina and are designed to stimulate the ganglion cell layer.

Subretinal Implants[edit | edit source]

Subretinal implants are placed behind the retina and are designed to replace the damaged photoreceptors.

Candidates for Retinal Implants[edit | edit source]

Candidates for retinal implants are typically individuals who have lost their sight due to degenerative retinal diseases such as retinitis pigmentosa or age-related macular degeneration.

Risks and Complications[edit | edit source]

As with any surgical procedure, there are risks associated with retinal implants. These can include infection, inflammation, and the possibility of the device failing or needing to be replaced.
