Rhodopsin Gene
Regulates metabolism, nucleic acid synthesis, and cell signaling
“Mis-folding” protein hypothesis
Altered signals induce premature transduction and decreased structural ability Molecular Analysis:
Retinitis Pigmentosa Rationale: Prevalence of retinal degeneration in visually impaired populations, and its role in innate and accident related ocular dysfunctions.

Research Inquiry: Why does the newly publicized bionic eye specifically target retinal degeneration, instead of replacement of the entire ocular organ? Eye Openers:
Statistical Evidence for Treatment Development 2012 – product of a visually stimulated and dependent society
Insist on inflicting our eyes with harmful neural activities, without the security of a cure
3.4 million people over the age of 40 are visually impaired or legally blind
1.5 million people suffer from AMD
1 million people diagnosed with RP Eye Openers:
