How much is a retina camera?
The price of a retina camera varied greatly due to a variety of factors. From January to September 2023, in the national bidding market of retina camera equipment, the average amount of Shandong, Shanghai and Liaoning was relatively high, with the average unit price of 1,151,900 yuan, 949,500 yuan and 935,300 yuan respectively; The average amount of Shaanxi, Qinghai and Hei Longjiang was relatively low, with the average unit price of 193,500 yuan, 180,200 yuan and 150,000 yuan respectively. In Qingyuan City's Hospital's eyeground screening camera purchase project, the price of the Netus Retcam3 was 1400000 yuan. In Shaoxing City Medicine Hospital's laser scanning opticoscopy (eyeground camera) purchase project, the winning bid price was 1280000 yuan. There were also low-priced models such as retro LCD digital cameras that might only cost 20 yuan, but these types might be more used for non-professional general photography needs rather than professional eye examination purposes.

Operating procedures of the retina photography instrument
1. Basic operation:
- He connected the power source and turned on the power source, display screen, and printer.
- Use the mydriatic agent to dilate the pupils (for some cases where the pupils need to be dilated, such as color photography and ordinary photography, but there are also cases where the pupils need not be dilated), and turn off the indoor lighting.
- He guided the patient to sit properly and moved the external fixative target to guide the patient's eyes.
2. Color photography:
- Set the filter switch to "N".
- He adjusted the eyepieces so that the crosshair on the eyepieces was the clearest, aimed the light at the patient's pupils, adjusted the main body to the front and back, and illuminated the patient's eyes in a symmetrical manner.
- He set the angle of view, used the normal color camera buttons to adjust the illumination, and pressed the shutter.
3. Photomograph operation:
- The preparation and adjustments were basically the same as those for color photography. During the examination, the patient usually sat in front of the retina camera, with his chin on the jaw rest of the machine, and his forehead on the fixed ring. Then, he stared at the visual target in the camera to prevent his eyes from moving. After the camera focused, it automatically took pictures.
Different types of retina photography instruments (such as true color, focal, and ultra-wide-angle retina cameras) may have different operations, and different examination requirements (such as whether to dilated pupils, different photography modes, etc.) will also affect the operation process. For example, the ultra-wide-angle laser scanning glasses generally did not need to be dilated. The patient would focus on the target, and the machine would automatically capture the image of the eye.

Is it normal for the retina of the eye to reflect light?
It was impossible to say whether the strong reflection of the retina was normal or not. In some cases, this may be a normal phenomenon. For example, the reflection of the retina of a dog's eyes is a normal physiological phenomenon. The principle is similar to the reflection of a mirror under moonlight. The structure behind the retina will reflect the moonlight and let us see its eyes "glow". However, in the human eye, the increased reflection of the retina artery could be caused by many abnormal reasons. For example, high blood pressure could lead to hardening and narrowing of the retina artery, which would increase the reflection of the retina. Retinal damage caused by diabetes, such as retina disease, would also lead to increased reflection of the retina artery. Arteriosis would cause the inner layer of the artery to be thickened, causing narrowing of the retina artery and increased reflection. There were also diseases of the eye, such as epilepsy or yellowish degeneration, which could also cause the reflection of the retina arteries to increase. In addition, the membrane before the macula was a layer of fiber proliferating membrane covering the surface of the retina of the macula, which would enhance the reflection of the retina of the macula, just like tin foil. This condition could cause visual distortion, decreased vision, and a sense of flashing. Therefore, if you find that the retina of the eye has a strong reflection and is accompanied by abnormal conditions such as decreased vision and visual distortion, you should seek medical examination in time.

Bionic Boyfriend
In the reference materials, there was a novel plot related to the android boyfriend. For example, there was a story where the husband sympathized with his wife's hard work and spent a huge sum of money to customize a bionic robot. This robot actually became a special existence that interfered with the family relationship, as if it was a mistress in disguise. There were also some stories that involved the role of the androids in family relationships, emotional entanglements, and other plots. For example, a person who was thought to be a android was used as a substitute and was sent back to the laboratory to be destroyed. There was also a mention of a product similar to the concept of a robot boyfriend in real life. He was 1.82 meters tall, had 8-pack abs, could skillfully complete all housework, had a powerful AI chip and self-learning ability, had a gentle and considerate personality, and was very good at providing emotional value.

What are the contents of the novel fragments about the retina?
I recommend " Super Golden Right Eye ". The protagonist Li Zhuihua's right eye was blinded by accident and miraculously recovered its sight. It was also created by the mysterious coffin and light into a golden right eye. It could see through things, move objects, and have more functions. It was not difficult to appraise treasures, gamble stones, and see a doctor.
" Crossing the Foreignland with the Shurunyan " was not bad either. The young man brought the Shurunyan across the Foreignland and displayed all kinds of Shurunyan abilities one by one. Let's see how he would dominate the Foreignland. However, there were some problems with this book, such as the BUG in the Shurunyan, the ability settings, and so on. The ending was also a little rushed, but the early content was still worth reading.
The story of Uncle Zhang after he accidentally entered the immortal mountain in " mistakenly entered the immortal mountain " was very interesting, and the character information in it was also very rich.
One Piece: Tom the Cat's First Friend was super fun. The main character was stranded in the world of One Piece. His first friend was Tom the Cat, and there were many other characters that were summoned later on. The relaxed and funny style was very attractive, but there were some shortcomings at the end, but overall, it was worth watching.
" The Killing Intent of Man, The Reversal of Heaven and Earth " was a Xianxia novel. It had the flavor of a Chinese story. The protagonist was a chivalrous man in troubled times. The author had changed from a sports novel. Although it was lacking, it was very unique.

Eagle Bionic Plane
The Eagle Bionic Airplane was an aircraft that was inspired by the flight pattern and physiological structure of eagles. In the field of bionics, the flight characteristics of eagles provided many references for aircraft design.
For example, the NASA Ames Research Center in the United States invented the winglet based on the feathers on the eagle's wingtip when flying. This structure used the principle of bionics to reduce the induced drag of the aircraft. The " Go Go Bird 1000 " released by Hanwang Technology was a high-simulation flapping wing aircraft. It drew inspiration from the flight mode of eagles in nature. It was 46cm in length, 60cm in wingspan, and weighed 138 grams. It could fly for 12 minutes on a full charge and could fly up to 40 meters high. It could be set to fly freely or controlled by its self-developed flight control software. It had low-voltage automatic return, autonomous obstacle avoidance, fixed-altitude flight, straight-line flight, and specific flight. It had a variety of human-computer interaction control functions such as a sensory switch.
In addition, the research team of the Northwestern Polytechnical University continued to explore the field of bionic aircraft and made the world's longest flight time. There were also model enthusiasts who made highly bionic eagle aircraft, and even the People's Liberation Army revealed a bionic drone that looked like an eagle. Not only could it flap its wings and adjust its posture like a real eagle, but even the sound it made was no different from a real bird.
The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!

What kind of medicine has an effect on retina atrophy?
The following drugs have an effect on the retina:
1. ** Antibiotic drugs **: For the retina atrophy caused by infection, the use of antibiotics under the guidance of a doctor, such as levofan eye drops, can help to improve the symptoms of retina atrophy.
2. ** Blood circulation and blood stasis dispelling drugs **: The patient's eyes are atrophied due to blood loss. It can be treated with blood circulation and blood stasis dispelling drugs such as Xuefu Zhuyu capsules.
3. ** Optic nerve protectant **: This is a condition caused by the atrophying of the retina. Optic nerve protectants may be needed.
4. ** Nervous nutrition drugs **: Such as mecobalamin tablets and muscle injection of rat nerve growth factor, which can enhance the resistance of the optical nerve to damage factors, promote the recovery of the optical nerve function, and play a certain role in the reduction of the retina.
In addition, the anti-vascular growth factor injection could be used to treat eye diseases. It was initially used for tumor treatment, but later found to have a very good effect on eye neovessels and other eye diseases. At present, there are such drugs specially developed for eye diseases, which may also have a positive effect on eye atrophy-related diseases. However, when using drugs, it is necessary to formulate a customized treatment plan according to the individual situation.
