Scientists achieved a milestone with a new technology called optogenetic therapy in which engineered goggles has restored the vision of a blind man partially.
The 58-year-old man was suffering from a neurodegenerative eye disease known as retinitis pigmentosa a condition where a patient loses complete eyesight due to the loss of photoreceptors.
According to the American Academy of Ophthalmology, Retinitis pigmentosa’s response to light changes somehow and it becomes difficult for the person to see. Scientists introduced the 58-year-old man to gene therapy for reprograming his eye’s retina cells which uses one component of different treatment of light sensitivity in the eyes’ cells.
And while the news is promising, there are still some improvements that are needed. For example, the patient cannot recognize faces or read although but they can locate, perceive, count, and touch objects by wearing the goggles.
After several months, the 58-year-old man has been able to identify furniture in a room, detect objects including a mug, plate, or phone, by wearing the goggles.
