What’s wrong with black shadows or flashes in front of my eyes? Middle-aged and elderly people over 40 years old or highly myopic patients sometimes have black dots suddenly appear in front of their eyes and fly around with the rotation of the eye, as if they were flying mosquitoes, with various shapes. Ophthalmologists, in general, the black shadow floating in front of the eye is mainly the eye within the vitreous cavity of the cloudy material due to block a part of the vision, the formation of a black dot in front of the eyes. This may be flying mosquitoes, such as black shadows, flashing symptoms to promptly go to the hospital for examination, to rule out flying mosquitoes. So, how to determine the symptoms of mosquito flying disease? 1, if there is a sudden sense of flash in front of the eyes, indicating the presence of vitreoretinal traction, in most middle-aged and elderly people often appear. It is recommended to visit the ophthalmology department, detailed examination of the fundus, to rule out retinal fissures, retinal detachment and other abnormalities, if there are above abnormalities need to be dealt with. 2, such as the emergence of “flying mosquitoes” in front of the eyes, for most middle-aged and elderly people is a normal phenomenon, for the vitreous clouding, is a degenerative disease, no need to deal with, the phenomenon can also appear in young people, especially highly myopic or had a traumatic injury to the population. 3, if there is a fixed black shadow in front of the eyes, or even the aura of flashing light, should be highly suspicious of the existence of retinal detachment, urgent consultation ophthalmology, detailed examination, such as the occurrence of retinal detachment, need to operate as soon as possible to reset the retina. 4. If the black shadow in front of the eyes is smoky or jet-like, vitreous hemosiderosis should be highly suspected. Most of such patients are accompanied by diabetes, hypertension and other systemic diseases, occasionally caused by posterior vitreous detachment, which requires urgent medical consultation and surgery in serious cases. Vitreous turbidity can cause retinal detachment Experts point out that: vitreous turbidity destroys the vitreous gel state and fiber scaffold structure, and the support effect of the liquefied vitreous on the retina is weakened, which is one of the factors that produce retinal detachment. According to your case, we suggest you go to a professional eye hospital for another detailed examination and treatment of the current vitreous turbidity to avoid other eye diseases and eliminate future problems. The presence of vitreous turbidity is sometimes a very important warning sign of some blindness-causing diseases. If treated promptly, it can prevent the progression of the disease and save your vision. Retinal detachment usually requires surgery, but if a careful examination is performed when the vitreous clouding first appears, sometimes a dry hole can be found and, with laser treatment, the formation of retinal detachment can be avoided, thus saving the pain of surgery. It is important to note that if there is a history of significant trauma prior to the appearance of vitreous opacities, with more floating black shadows in front of the eyes that arise more quickly and suddenly, along with a sense of flashing light and loss of vision, this is often a manifestation of such disease and requires prompt medical attention.
