The British NHS introduced a new type of X-ray treatment to treat senile blindness. This method can treat age-related macular degeneration (AMD) in one dose, and about 250,000 people in the UK are sick.
X-ray treatment for the treatment of "wet" AMD is caused by abnormal blood vessel formation in the macula.
Monthly eye injections are a routine treatment, but X-ray therapy called Oraya treatment can see half of the treatment.
The cost of each treatment is £700, which means that the NHS can be reduced and the inconvenience caused to the patient is reduced.
This method provides patients with a painless, highly targeted, and low-radiation treatment. Patients receive radiation that is equivalent to one dental radiation, and some do not require retreatment after three years of treatment.
The AMD-affected population is older than 60 years of age. The progression of wet AMD is particularly rapid, with approximately 26,000 people getting sick each year. There is currently no cure for the disease, but laser surgery and drugs can limit the damage caused by the disease.
Doctors at Sheffield Hospital are now using Oraya therapy to illuminate the patient's damaged fundus with a dose of radiation. The time required for this non-invasive therapy is only a few minutes.
The principle of the therapy is to dry the uncontrolled leakage of new blood vessels. Reduce scars by focusing the beam to the fundus.
The researchers said that European clinical trials have shown that the therapy reduces the monthly injection by 45%, but patients still need to review it regularly. In the ideal state, patients should not be injected again after treatment and their condition will become stable.

The Wireless CCTV Kit / Wireless CCTV Kits/ CCTV Kits Wireless/ CCTV Wireless NVR Kit/ Wireless CCTV Kit Outdoor/ wifi CCTV Kit is the combination of the Network Camera and the Network Video Recorder. Let me introduce you the Network Camera and the Digital Video Recorder respectively.
The Network Camera, also called the WEBCAM, WEB CAMERA, or IPC, is the new generation which combines the traditional camera and the network technology. And the Network Camera can normal do the monitoring function with the help of the standard web browser such as the Microsoft IE or Netscape. Besides, the Network Camera also has the built-in digital compression controller and a WEB-based operating system, which makes the compressed and encrypted video data delievered to the final user via the local area network, internet or wireless network. Then the remote user can visit the Network Camera via the standard web browser on PC according to the IP address of the Network and then monitor the on-site video, edit and store the image data, and can even control the camera such as adjust the PTZ and lens of the Network Camera to monitor the target area in all directions. Very convenient, isn't it?
The Network Video Recorder, Also called the NVR, is the corresponding video recording device to the Network Camera, the video capture device. The Network Video Recorder can receive the digital video stream transmitted by the Network Camera via the network to store, manage, and then to realize the advantages of the distributed architecture brought by the network. Simply speaking, the user can watch, browse, play back, manage, store several cameras at the same time and would never worry about the complicated software installation because the computer hardware would not be a limitation for the operation of the wireless CCTV kit.
What is the advantage of the Wireless CCTV Kit?
As the web technology grows so fast, the function of the Wireless CCTV Kit also becomes more and more powerful. The Wireless CCTV Kit has no limitation from the cables so its setup will be easy and its usage is also very simple. Furthermore, the resolution of the Wireless CCTV kit is also wonderful because of its image dealing way.
As time goes by, the Wireless CCTV Kit is more widely applied to all kinds of fields and it would be a good choice for us to choose the Wireless CCTV kit in the terms of its powerful function and convenience.
