As a prerequisite to answer your question, it depends on which types of retinal cells are damaged. For example, Professor Zrenner and his team at the University Hospital Centre in Tübingen (Germany) have developed electronic retinal implants to attempt to restore the vision loss observed by the loss of retinal photoreceptor cells in retinitis pigmentosa.
Hello Toluwanimi Oluwadara Akinyemi, Kristian Nzogang Fomo
I'm not an expert and I don't even have expertise in the subject but I made a little search and found some interesting for you, I don't know if you already know about this but there is a specific site that approaches this subject. What I learn is that treatments for most disorders that cause vision loss are difficult or not yet possible. Specialized cells in the eye serve specific functions to focus light and turn what is being seen into signals sent to the brain. The eye contains several types of stem cells that constantly replace specialized cell that become worn out or damaged.
