What are the retinal diseases?
The retina is located in the inner layer of the eye wall, which is a very thin but very complex structure. In the retina, there are rich photosensing cells, equivalent to the camera photographic substrate, specialized for photographic imaging. When we look at things, light needs to pass through the eye refractive system and focus just on the retina to be transmitted to the brain through the optic nerve to build an image.
Retinal diseases are mainly divided into two categories: vascular diseases and neurological diseases. Among them, vascular diseases include retinal artery obstruction, hypertension or diabetes caused by fundus lesions, while neurological diseases refer to macular degeneration, optic neuritis, papillary edema, etc. In addition, there are some trauma, infection and so on will also affect the retinal lesions. Retinal lesions will directly lead to different degrees of visual impairment, including central vision loss, color vision disorders, visual deformation and so on.
In addition to the diseases mentioned above, you may have heard of retinal detachment. Due to the sudden contraction of the vitreous, and the retina pull force, resulting in the formation of retinal breaks or blisters, this is retinal detachment, it will lead to a sharp decline in vision, or floaters, flash feeling, may also cause sudden blindness. Retinal detachment is more commonly seen in patients with high myopia and the elderly, or in people suffering from severe trauma.
Because the treatment success rate of retinal disease is closely related to the morning and evening of discovery, so once there are related symptoms, you need to go to the hospital as soon as possible, dilated pupil examination fundus or fundus fluorographic examination. Although many diseases cannot be completely avoided, but can avoid risk by reducing the risk factors, such as diabetes patients strictly control blood sugar levels, according to the doctor's advice use hypoglycemic drugs, such as long exposure to the sun, by physical sunscreen reduce the risk of macular lesions, such as change such as smoking, drinking bad habits. In short, we must do regular fundus screening, to facilitate the timely detection and tracking of retinal diseases.
