Boy was slapped more than 40 slaps to the left eye nearly blind Recently, there are media reports Zhoukou a boy, Xiao Dong, was punished by teachers slapped for not completing homework on time. Xiao Dong was slapped by more than 20 classmates each, and that night Xiao Dong went to the toilet and found that he could not see out of his left eye, but was not taken seriously and did not seek medical attention. Some time later, Xiao Dong’s mother took her child to a local hospital for inpatient surgery, where doctors diagnosed blunt contusion of the left eye and retinal detachment, facing the possibility of blindness. Many readers expressed great indignation at this incident, the boy’s experience of deep sympathy, but also can not help but question, slapping can actually “fan” bad eye? For this reason we interviewed Dr. Zheng Bin, deputy director of the Fundus Center at Zhejiang Eye Hospital Hangzhou. “Xiao Dong retinal detachment, can not exclude the eye was hit by external force after the possibility of retinal fissures.” Zheng Bin said that a simple injury to the face will not cause retinal detachment, but when the eye has been subjected to an external force causing retinal rupture, the intraocular fluid or into the fissure will lead to retinal detachment. Zheng Bin further explained that the vitreous humor in children’s eyes supports the retinal tissue like jelly, and the retina generally does not detach immediately. However, with the prolongation of the trauma or the repair of the tissues in the eye after damage, retinal detachment can occur some time after the trauma. If the boy’s retina detached immediately after the trauma, it means that the force was so great that the retina may have even torn off. Ocular trauma in children with this type of “hindsight” is one of the most common and difficult ophthalmic emergencies. Because of the child’s inability to cooperate, it often leads to missed diagnoses and delays, and most serious children have a poor prognosis, not only for loss of eye function, but also for serious psychological damage. Dr. Zheng Bin reminded that parents should try to avoid exposing their children to dangerous toys or objects to prevent their eyes from being injured by external forces, and children with eye or head injuries should also go to the ophthalmology clinic in time for a check-up. Zheng Bin introduced, in recent years, due to eye impact caused by this child’s retinal detachment occurs frequently, but in daily life, retinal detachment is more likely to occur in middle-aged and elderly people around 50 years old and myopic eyes. Vigorous shaking of the eye can also lead to retinal detachment “Retinal detachment is the result of several factors, in addition to the external forces mentioned above, the vitreous liquefaction pull and the retinal degeneration zone play a very important role in it.” Zheng Bin explained that the vitreous body is the main part of the eye, and when it is normal, it wobbles very little in the eye, making it difficult to cause traction on the retina. But when the vitreous liquefaction, it becomes a “water bag”, the magnitude of shaking in the eye is significantly enhanced, if the impact on the retina will produce a “flash sensation”. Zheng Bin said, vitreous liquefaction is most common in myopia and the elderly, unlike young people, the elderly vitreous will gradually produce post-detachment. When the retina has a degenerative zone, it is closely connected to the vitreous, and when the vitreous detaches here, it will cause a pull on the retina, and a “flashing sensation” will occur, and when the eye turns violently, the pull will suddenly increase, and in severe cases the retina will tear. Does the presence of a fissure in the retina necessarily lead to detachment? Dr. Zheng Bin does not think so. Dr. Zheng Bin recalled that he had seen an elderly patient who had learned a new type of eye exercise with others the first night and kept shaking his eyes from side to side. Fortunately, the retina has not detached in time for medical attention. “It is not recommended that the elderly deliberately shake their eyes violently.” So said Zheng Bin. Zheng Bin suggested that people who are prone to retinal detachment should go to the ophthalmology department to check the fundus in time, and if retinal degeneration is found, they may have to receive fundus laser treatment. If there is a sudden increase in black fluttering in front of the eyes, or if the flashing sensation is obvious, you should also go to the hospital as soon as possible for examination to prevent delaying the condition. Reminder How to avoid retinal detachment in life? Zheng Bin reminded that myopic patients and the elderly, must avoid violent shaking of the eye or head, especially violent impact of the eye. With the arrival of the Chinese New Year, children’s eye trauma enters a high incidence period, children are often injured by firecrackers or toy pistol BBs, so parents should avoid exposing their children to firecrackers as much as possible, and do not buy dangerous toys for children.
