A new cure for users suffering from a type of congenital retinal blindness has displayed success in enhancing vision, as per results posted this week in Nature Medicine spearheaded by scientists at the University of Pennsylvania at the Scheie Eye Institute in the Perelman School of Medicine.
The treatment was developed for users suffering from CEP290 mutations and who has a diagnosis of LCA (Leber congenital amaurosis). CEP290 acts as an entrance between 2 departments of photoreceptor cells. These cells are a type of sensory neuron in the eye that turns light into signals that offer vision. Primary photoreceptor blindnesses (such as those resulted due to CEP290 mutations) are the most ordinary type of LCA and they are present non-curable.
In this clinical research at areas in Europe and the United States, participants got an oligonucleotide’s intraocular injection (which is a tiny RNA molecule) created to lower the protein levels of mutant CEP290 in the photoreceptors and re-establish retinal operation.
On a related note, people who suffer from migraine with visual aura might have an elevated danger of an uneven heartbeat dubbed as atrial fibrillation, as per a research posted in online issue of Neurology®, American Academy of Neurology’s medical journal. Migraine coupled with visual aura is when disruptions in vision take place prior to when head pain starts. Those disruptions might comprise seeing flashes of light or wavy lines, or having blind spots or blurry vision.
When suffering from atrial fibrillation, a kind of arrhythmia, the normal rhythm of heart is out of sync. Consequently, blood might gather in the heart, possibly making clots that might go to the brain, resulting in stroke. “Since atrial fibrillation is a widespread source of strokes due to blood clots, and earlier study has displayed a connection between migraine with stroke and aura,” claimed Souvik Sen, study author, to the media in an interview.
