If the eye disease is not particularly serious, it will generally not attract our attention. However, for some diseases that are highly blind, it is still necessary to intervene in time, but then it is very serious. According to statistics, the most common eye diseases in China are: cataract, glaucoma and diabetic eye disease. Cataract is currently the leading cause of blindness in China. The prevalence rate of elderly people over 75 years old is as high as 91%. Glaucoma is also very powerful. It is characterized by eye pain, severe pain and high intraocular pressure in acute attacks. It can be completely blind for 24 to 48 hours. It is an irreversible blind eye disease. At the same time, the proportion of retinopathy in patients with type 2 diabetes within 5 years is as high as 40%, and this complication is as high as 84% ​​in patients with 19-year course. The blindness rate of diabetic patients is ordinary. 10 to 20 times that of people. In fact, 80% of the world's blindness is preventable, the key is early screening and early treatment. However, the tools needed to solve eye problems in the past are often heavy, clumsy, difficult to operate, and inconvenient to conduct extensive screening in economically underdeveloped areas. Therefore, many mobile medical companies have begun to develop more convenient and low-cost inspection equipment to help more people to easily obtain eye examinations. SVOne helps ophthalmologists get out of the office New York-based startup Smart Vision Labs recently developed SVOne, a handheld portable replacement for automatic diopters. Priced at just $3,950, the SVOne is able to diagnose patients at any location with the iPhone's lens, processor and wireless connection and help them manage their cases online. The traditional refractometer is about the same size as a microwave oven and costs up to $20,000. The SVOne is a silver tablet that weighs about 0.9 pounds (about 0.4 kilograms) and the size and size of the entire device is much like a paperback book. One end of the device is equipped with an eyepiece and the other end is equipped with an iPhone. SVOne is very portable, making it easier for doctors to use and bringing gospel to patients around the world. Marc Albanese, one of the two co-founders of Smart Vision Labs, said: "The functionality and processing power of the iPhone camera is very advanced, and we used it in advanced research laboratories decades ago. The technology is comparable." To know that Mark is not the latest iPhone device, but the iPhone 5s series two years ago. SVOne is not a reduced version of the automatic refractometer, it is a more sophisticated device - the leading wave aberration analyzer. In laser corneal surgery, we use this type of equipment to guide the laser for surgery. SVOne can project a grid of about 100 red dots on the patient's retina, and then the iPhone camera will take a photo of the red dot grid as the light is emitted, and then the application developed by Smart Vision Labs will measure the image. If the spot position in the photo is outside the original mesh, the patient's eyes appear hyperopia; if the spot is inside the mesh, the patient's eye is suffering from myopia; if the picture in the photo is oval, the patient has astigmatism . The SVOne device can measure a variety of diseases, so it can also diagnose diseases such as night blindness. The pupil of a night blind person will expand in the dark, and the passage of light at this time will cause the patient to see the object. Smart Vision Labs will also add a new accessory to SVOne to turn it into a power meter. In turn, SVOne can detect the degree of eyeglass lenses currently used by patients. In addition, SVOne can also display an eye chart for patients to check their vision. The SVOne device automatically uploads patient test results and test instructions. With SVOne, you have a handheld portable optometrist or an ophthalmologist. It also automatically records the stored test results. Albanece said: "With this device, doctors can diagnose eye diseases for patients almost anywhere." At present, many doctors take SVOne to a nursing home or school to see patients. In the 2013 Verizon Powerful Answers contest, Smart Vision Labs won a $1 million prize for its products to help people in poor areas see the light again. But Smart Vision Labs is not a charity, and they have since received $6.1 million in investment from investors. They have sold more than 200 SVOne devices, most of which are sold to American doctors. Service is also one of the purposes of this company. When they were finalizing the details of the equipment last summer, Albanese and others had begun to take SVOne to the poor areas of Haiti and Guatemala to conduct eye tests for the local poor. Albanese said: "That was the first time we used equipment in practice." In addition, they also brought old glasses donated by many good people, trying to find the most suitable glasses for patients. Since then, SVOne has played a role in approximately 20 countries around the world, including Ecuador, the Gambia, India and the Dominican Republic. Smart Vision Labs also sold some SVOne devices to Community Enterprise Solutions, a non-profit organization that fosters entrepreneurship in developing countries. Where there is no network connection, SVOne can run offline and store the test results in the device for later uploading data when networked. However, there are no network connections in some areas, so many charities are interested in the cloud service components of SVOne devices. Cheap and great product Peek The Portable Eye Examination Kit (Peek) is a smartphone-based eye disease diagnosis system. Through a 3D printed plastic camera bezel and corresponding software applications, Peek can turn the smartphone into an eye disease detection tool that allows the ophthalmologist to perform detailed, thorough eye exams on the patient. Developed by several British ophthalmologists, Peek successfully raised £130,000 on the crowdfunding site Indiegogo in May this year. Peek can use the high-quality camera of the smartphone to observe the retina, check the cataract, and perform visual acuity, color and contrast tests. Peek aims to help approximately 39 million consumers worldwide who do not have access to basic eye care services. Bastoros said at the TED Talk conference that the study aims to help patients in developing countries receive better eye care services, including cataract removal and prescription lenses to restore vision. The medical images taken by Peek can also be sent to the doctor remotely, allowing the doctor to diagnose and give a treatment plan. Peek can solve eye care in any part of the world with just a cheap smartphone and matching accessories and applications. Interestingly, Peek can also perform vision tests by displaying smaller and smaller letters and numbers, and color-blind tests by similar methods. eyeMITRA, early detection of diabetic eye disease Diabetic retinopathy is an important cause of blindness, and eyeMITRA (MITRA: the acronym for "Removal Retinal Imaging and Predictive Analysis") is a mobile retinal imaging and predictive analysis tool that screens for diabetic eye disease. With sensors attached to the phone, it allows diabetics to self-test at a lower cost, and a diabetic retinopathy can be detected with a glance at the phone. The technology was developed by the Camera Culture Group, a division of the Massachusetts Institute of Technology (MIT) Media Lab, led by Ramesh Raskar. Rasca was first introduced in 2011 in developing countries using a mobile tool EyeNetra for vision testing. EyeNetra initially prototyped at MIT, and then became a commercial startup with the support of venture capital firm Khosla Ventures. Two years later, the Indian scientist developed another camera-based diagnostic tool, eyeMITRA. He believes that the ability of this new tool far exceeds that of helping people with glasses. eyeMITRA is quite cheap, and each piece will cost between $20 and $50, especially for patients in developing countries who are unable to perform regular eye exams, allowing them to assess their eye health. “A doctor can save a life at a time. As a technical expert, we can save the lives of dozens of people at a time through the tools we create.†Lasca said.
