Retinal detachment is one of the more serious and common blinding eye diseases. It occurs mainly in highly myopic eyes, in the elderly, and in eyes that have been traumatized. The retinal tissue is complex, delicate and fragile, and has a vigorous metabolism. The retina itself is made up of nine neurosensory layers. If we compare the eye to a photographic camera, the retina is the equivalent of the photographic film in the camera. Retinal detachment is the separation between the film base and the photoreceptor material, resulting in a series of clinical symptoms due to the disruption of the eye’s photoreceptor system. Types of retinal detachment Retinal detachment is divided into two categories: primary and secondary. Secondary retinal detachment is caused by other diseases of the eye such as exudative retinal chorioretinitis, trauma, hemorrhage, choroidal tumor, etc. The etiology of this secondary retinal detachment is relatively clear, and once the lesion is removed, the retina can be restored to its original position. Primary retinal detachment means that the cause of its occurrence is unknown. It is generally believed that the key problem is the formation of a retinal fissure, which allows the melted vitreous to pass through the fissure and infiltrate into the subretinal space. This condition occurs most often in highly myopic eyes. In addition, it can also occur in areas of degenerative atrophy and cystic degeneration caused by age-related changes in the retina, allowing the formation of a fissure and resulting in retinal detachment. The main symptoms of retinal detachment: 1. Before the occurrence of retinal detachment, there are often spark and flash hallucinations. 2. Sometimes a dark cloud-like shadow is felt in front of the eyes advancing from one side toward the central part of the visual field. 3.Blurred vision and distortion of visual objects. 4.Sudden loss of visual acuity. 5.Decrease in intraocular pressure and softening of the eyeball. If the above conditions occur, you should go to the hospital for examination, diagnosis and treatment in time, and should not delay the code rate in order to miss the opportunity of treatment. Prevention of retinal detachment Retinal detachment is more difficult to recover, and the surgery is also very difficult. However, before the sexual detachment, it is necessary to do a good job of prevention. 1.It is not easy to overexert your eyes. 2.Do not lift heavy objects. 3.Do not do strenuous activities. 4.Prevent the occurrence of myopia. 5.Patients who suffer from myopia should go to the hospital regularly for examination, especially for myopic patients with bad fundus. 6.Prevent eye trauma. The treatment of retinal net detachment 7, net detachment light, bed where a few days, pay attention to the lying position, eat more fruits, vegetables, light diet, do not chew hard things, keep the bowel movement smooth, net detachment some can be reset. 8, net detachment heavy, must be surgical treatment, the sooner the better, as long as the above-mentioned net detachment symptoms are found, should immediately go to the hospital for examination, diagnosis and treatment.
