RESUMO
@#Retinal degenerative disease is a major disease that affects human vision. It damages human photoreceptor cells and damages human vision. And the mammalian retina does not have the ability to regenerate, once the disease will seriously affect people's normal life. At present, there is no clear way to prevent and alleviate these diseases, but the transplantation of photoreceptors to supplement the damaged photoreceptors in the retina can treat retinal diseases. In this paper, we will discuss the current situation and techniques of photoreceptor transplantation to restore vision in retinal degenerative diseases.
RESUMO
Age-related macular degeneration(AMD) is the major cause of irreversible damage to vision in over 60 years old.Its incidence is increasing with age.Dry AMD is one of the most common types,causing the loss of vision is very slow.At the late stage,the geographic atrophy will be found,in which central vision is severely lost.It is widely believed that chronic inflammantion injury,oxidative stress injury,lipofuscin,drusen and choroid ischemia are the major pathogenesis.Now,the treatment is major aiming to the pathogenesis.But some new therapies such as crocetin,curcumin,ciliary neurotrophic factor,nanoceria,human monoclonal antibody,photoreceptor and stem cell transplantation have some efficiency to dry AMD.This article reviews the research advances in therapy of dry AMD.
