Laser pointers are often sold in life, especially in children's stationery stores, toy stores, pet stores, online, etc., in fact, this laser pointer is very dangerous, and direct irradiation of the eyes may cause irreversible and permanent damage to the eyes.
Today, I will popularize a common case encountered in clinical work to popularize the damage of laser pointer to the eye.
The seven-year-old child Qiqi (pseudonym), a month ago, went to the optician to get glasses because of poor vision in his right eye, and his eyesight did not improve. Comprehensive refraction showed that the best corrected visual acuity in the right eye was 012, cannot be raised to 10。Further tests were then ordered.
Optical coherence tomography (OCT) showed loss of signal in the fovea of the ellipsoidal band, myoid area, and chimeric area.
Finally, it was clarified that Qiqi's poor vision was caused by macular lesions in the fundus, macular area was damaged, and the foveal structure was damaged, resulting in poor vision. We repeatedly asked the child whether he had skied, whether he had seen the sun, whether he had seen a solar eclipse or a lunar eclipse, whether there had been a light shining his eyes, etc., and finally Qiqi's father said that he had just bought a laser pointer for teasing cats last month, and Qiqi would use a laser pointer to tease the cat every day, and the culprit was this laser pointer, but unfortunately because the Qiqi laser pointer burned the eyes for too long, the fundus was seriously damaged, resulting in irreversible vision.
Laser products are harmful to the eyes, because of their high energy, direct eye vision can easily cause permanent, irreversible macular damage, and even cataracts, and even damage**, so parents of children must stay away from laser pointers to protect their eyes.
