High myopia usually refers to myopia of 600 degrees or more. As myopia deepens, the length of the eye axis is gradually stretched, and in the process the retina is gradually stretched, so the firmness decreases, and during the process of delivery due to the excessive changes in intra-abdominal pressure, so the risks brought about mainly include two aspects: the first one is easy to develop macular edema or retinal edema; the second one is easy to cause retinal fissure or retinal detachment. Therefore, for high myopia, we must pay attention to the changes in vision during the whole period of labor, and once the dark shadows in front of the eyes obscure or floating objects, vision loss, these symptoms, we should go to the ophthalmology department for detailed fundus examination as soon as possible to clarify whether there are any of the above complications, and if there are, we should treat them in a timely manner.
