PPT-Retina and Vitreous

Retina Retina The innermost layer of the eyeball It is extremely thin and transparent 05mm It contains visual receptors of the eye The retinal neurons transmit the picture through the optic nerve fibers to brain for perception. Temporal filtering . – visual response slower than input signal. . 2. Spatial filtering . – local signals are combined across space to varying degrees.. . . 3. Light adaptation . – retina modifies responsiveness depending on average light level.. Dr.Bakhtiar. . Qadr. . Jaf. بسم الله الرحمن الرحيم.

By: Danny Alvarez 4/29/15. Artificial retina imaging has made great improvements in the last decade, and is poised to make an even larger advancement in the near future. In the future those with retina damage caused by retinitis pigmentation could once again see in 20/20.. When a person has lost their sight to a damaged retina there is now technology that allows them to see again. By means of a chip which sends electrical signals to the optic nerve. They then have their sight partially restored.. Monday, April 18. Mike Vue. Artificial Retina allows someone who has lost their vision to see again. The technology is implanted in the eye and it sends signals to allow the person to see.. Table of contents. . etc.venues. . St. . Paul’s. E. valuation. attendance.
