The clichéd topic, it seems that many people have the symptom: suddenly found in front of the eyes there are tiny or dotted or smoke ring-like things floating around, registered to see, the doctor said vitreous turbidity or mosquitoes, nothing, go back to observe on the good. The doctor said that the eye was cloudy, but many people were still not satisfied and continued to change doctors or hospitals to see, so the doctor gave an eye ultrasound, oh oh, the first time I heard of eye ultrasound, many people said so. ultrasound suggests that it is really vitreous turbidity, will believe it, well, go back to observe it. After a period of time, hmmmm, how to fly more things, sometimes there is a sense of flash, go back to see, dilate the pupil to check the fundus, well, nothing, go back to observe. We registered so hard ah, half a day queue, say a minute, come when you do not understand, go when confused, hum, this disease to see …… In view of all the above, I suddenly want to talk about this disease, flying mosquitoes is also called flying pattern phantom disorder (cited my teacher Professor Wei Qi Ping), since it is phantom vision, is that you stare at the white wall and so on for half a day, you will found, sometimes busy forgetting, and do not remember this thing. What’s happening in the eye? When you are young, the vitreous humor is very strong, but as you age, the vitreous humor liquefies, and this “jelly”-like stuff – the little liquefied water droplets – floats with the eye as it turns, so the above phenomenon occurs. So should we leave it alone? The sudden appearance of or to see, especially the sudden blurred vision, shadows in front of the eyes, a sense of flash in front of the eyes, red eyes and other symptoms, if you can dilate the pupil to check the fundus, to see if the peripheral retina degeneration, fissures, there is no inflammation, there is no risk of retinal detachment, the trip is worth more. In addition, there are no side effects for most people, except for some patients with closed-angle glaucoma who need to be cautious about dilating their pupils, so other friends don’t have to worry about it.
