Retinal neurodegenerative diseases like agerelated macular degeneration,glaucoma,diabetic retinopathy or retinitis pigmentosa are the most frequent causes of incurable low vision and blindness *** had been estimated that the prevalence of these diseases varies between 1/750 and 1/5000 depending on the region,the level of consanguinity or ethnicity(na et al.,2017).The functional and structural complexity of the retina makes it susceptible to multiple types of pathogenic damage.
