I'm Zhao Xiaodao and I'm an ophthalmologist.
At the end of February this year, the fundus living cell microscope - Star Mirror was launched, and Ling'er and many children who were undergoing red light therapy were examined. Recently, some children have completed the second follow-up, and one parent shared the results of the 2 astroscopic examinations: all are very good.
The Star Scope, a fundus live cell microscope, was launched, which was able to directly observe the details of the fundus cells, and realized the detection of cone cell density that was previously only available in academic literature. In the past, the safety of the fundus was based on clinically detectable abnormalities, but now with the astroscope, we can give a clear evaluation at the more stringent cellular level.
Although we have long been clearly aware of the amount of diffuse transmitted red light fundus radiation at a large opposite angle based on clinical practice and theoretical projections, and there is no possibility of burning the fundus, not all professionals have the relevant knowledge. Some people who lack practical experience pat their heads and express that "red light will damage the fundus of the eyes, but now they can't observe it", which makes many parents suspicious, stops moving forward, and delays many children. However, with the advancement of science and technology and the deepening of research, the emergence of fundus live cell microscopes such as astroscopes has enabled us to observe the condition of fundus cells more directly and accurately, which helps to eliminate parents' concerns about the safety of red light therapy. Now, if there are potential risks associated with red light therapy, we have more precise tools to observe and analyze them, rather than relying solely on assumptions or speculation.
For those who oppose red light treatment, the advent of the star mirror means that they can no longer question the safety of red light based on subjective assumptions. Medical decision-making and health recommendations need to be based on empirical and scientific evidence, and technology such as astroscopes, coupled with a large number of clinical practice observations, provide a stronger foundation for this. As a result, the criteria for fundus safety will become clearer.
The kid uses the same three things: red light, a telescope, and a fog screen. Parents said that it was annoying to encounter arbitrary attacks on red light in other groups every day. He has been following my official account for 3 years, and the baby started 4L at the age of 5, and he is 7 and a half years old this year.
The child started with a lighting makeover, and after 8 months, he was on the fog screen, then the red light and the telescope.
He watched me read a lot of popular science, and he also drilled very deeply. Therefore, unlike many other parents, the prevention and control of the child begins when he still has farsightedness reserves. "Before using the fog screen, the farsightedness reserve was stuck for 2 years, but the growth rate of the eye axis was faster than the physiological growth (the lens compensation is obvious), so it was red light. ”
After using the fog screen, the child's farsightedness reserve has been maintained well, but the parents still want to control the eye axis more strictly. He concluded, "My personal opinion is that when there is a reserve of farsightedness, foggy vision therapy is likely to take precedence over lens compensation over axial control".
As soon as he summed it up, there is no doubt that the 4L student is a master. The characteristics of fog vision treatment are indeed the first lens, then the eye axis, there is time dependence, 1 hour a day can be used about 40~50 minutes, fog vision treatment is not as immediate as red light treatment, it works slowly, but mild, long-lasting, the longer you use, the better the effect, many parents describe that "stamina is enough, the ceiling is high".
Parents are not satisfied with maintaining farsightedness reserves, and look at the growing eye axis and glow red. After 7 months, the eye axis regressed (the probability of regression in children who have not yet myopia is actually relatively low). Seeing the current prevention and control effect, parents are relieved. "According to the corneal curvature and the eye axis, the farsightedness reserve is still above 150 degrees", the eye axis is also controlled, from the age of 5 to be myopia, pulled back to a relatively normal state, the contrast of the astroscopic examination is also normal, it can be said that everyone is happy.
When I still have farsightedness, I use red light, and my parents said that this is a decision he made based on his long-term follow-up of my popular science. He felt resentment and regret at the demonization of the red light.
Some doctors who lack clinical experience claim that red light therapy will illuminate the fundus, this view is not based on facts, but more from the fear of the word "laser", clinical red light has been "de-laserized" for two and a half years, and the red light with a large opposite angle has long physically avoided the fundus risk of laser, but some people are still scaring parents with "laser". The root cause is a lack of cognition and a lack of understanding of the development and parameters of red light, which results in delaying the prevention and control of many children.
The current red light is the diffuse and diffuse transmission of "de-laserized" red light that has undergone "conservative treatment", which cannot be gathered in the fundus, and has a thicker safety redundancy, and the serious adverse reactions of laser burns that everyone is worried about can be completely avoided.
In addition, with the advent of the astroscope, the exposure threshold of 650nm red light damage in the fundus has been clarified with long-term observation: the exposure of the fundus (RRE energy density) reaches 2000 J/cm2, and damage begins to occur, and there is no damage below this, the traditional red light energy density is 400 J/cm2, and the diffuse transmission red light energy density is 3 J/cm2, which is far lower than the threshold. Since then, the safety of red light therapy has been widely known.
Well, that's all for today's sharing. The examination is a test that many parents have recently been interested in and consulted, and it is also a test that I recommend everyone to do, and this test is expected to gradually spread to provincial capitals by the end of this year. Diffuse diffuse transmission of red light that does not gather in the fundus has a very high fundus safety. Instead of thinking too much about the future, it is better to use the power of the "Star Mirror" and OCT joint monitoring to clearly and accurately understand the condition of the fundus, and enjoy the dividends brought by red light with peace of mind.
