Retinal detachment clinically refers to retinal detachment, blindness commonly known as blindness, refers to the best corrected visual acuity is less than 0.05. Different types of retinal detachment have the possibility of blindness.
1. Retinal detachment of foraminal origin: the scope of detachment ranges from limited detachment to total detachment, and when the detachment involves the macula, the vision loss is obvious. Surgery is needed to close the hole and reset the retina. The degree of postoperative visual recovery depends on whether the macula is involved and the time of detachment. If the macula is not involved and the detachment occurs within 1 week, the prognosis of visual acuity is better.
2. Pull retinal detachment: the detached retina surface can be seen with the adhesion of the proliferative membrane or mechanized tissue, the scope and size of the adhesion will affect the shape and scope of retinal detachment. The severity of vision loss in detached retina depends on the extent and speed of progression of the primary disease. If the primary disease continues to progress for a short period of time, the visual acuity is poor.
3. Exudative retinal detachment: the detachment site changes according to the body position, the retina usually has no fissure, and usually has the clinical manifestations of the primary disease, and the severity of vision loss is very much related to the vision changes of the primary disease. The degree of vision loss is very much related to the change in vision of the primary disease. Active treatment of the primary disease is needed to improve vision.
If retinal detachment is detected, it is recommended to consult a doctor as soon as possible to improve vision and reduce the possibility of blindness.
