   en.wikipedia.org/wiki/Retinal_implant

   The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD). Retinal implants are being developed by a number of private companies and research institutions, and three types are in clinical trials ...

3. Visual prosthesis - Wikipedia

   en.wikipedia.org/wiki/Visual_prosthesis

   The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy ...

7. Intravitreal injection - Wikipedia

   en.wikipedia.org/wiki/Intravitreal_injection

   Intravitreal injection was first mentioned in a study in 1911, in which the injection of air was used to repair a detached retina. [6] [7] [8] There were also investigations evaluating intravitreal antibiotics injection using sulfanilamide and penicillin to treat endophthalmitis in the 1940s, yet due to the inconsistency of results and safety concerns, this form of drug delivery was only for ...
