Technology has been the key to the developments made in the fields of medicine and biology. This technological shift is accelerating the invention of a breakthrough in the field of optometry. Research is being conducted by American fellows to introduce latest non-invasive method of retinal imaging to help assist in prohibiting the onset of vision loss and many other optometric issues and complications in issues such as glaucoma.

According to reports, the group was led by David Williams from the University of Rochester, and they did work upon distinguishing ganglion cells. The research is putting emphasis on the portions that suffer maximum of the responsibilities of relaying individual data to brain.

Multiple diseases such as glaucoma, retinopathy, and retinal xerosis can be treated successfully by the research results. However until the retinal fibre thickens or any other change happens a patient generally loses 1, 00,000 RGCs.

RGCs being transparent are not generally visible, but Ethan A Rossi, Professor at University of Pittsburgh and his colleagues did put effort to visualize RGCs by modifying and changing by working upon a current technology. “Confocal-Adaptive-Optics” – opthalmoscopy is the breakthrough in this specific field. The team’s hard work and endeavour did include collecting multiple images, comparing their size and locations, using detector to get together the light which has spread out from retina, combining the pictures by a technique called  multi offset detection.

This allowed the group to visualise the RGCs and the ability of distinguishing nuclei in animal cells acted as the ‘cherry on top’.
