Almost all of us, at some point in our lives, have observed a kind of floating spots in our field vision. A type of ‘floaters’ that seem to dance in front of us no matter where we look and that, due to our ignorance, can worry us. But what are they really?
Although at first glance they may seem strange, these floating points or filamentsknown as myodesopsiasare very common and, in most cases, less dangerous than one might think.
What causes these ‘floaters’ we see floating in our eyes?
These ‘floaters’ are made up of small accumulations in it vitreous humorthe gelatinous substance that fills the inside of the eye, which maintains the shape of the eyeball and allows the light happens clearly towards the retina, the layer where images are projected. As we grow oldthe vitreous humor tends to shrink and, in that process, the fibers that compose it can begin to fall apart or become fibrous. These fibers, when moving, project shades on the retina, generating the blurry images that we perceive as floating spots. This is why, often, we see them more clearly on light backgroundslike a blue sky or a white wall.
For most people, myodesopsias are not a serious problem, and although they may be annoying at first, over time They tend to settle at the bottom of the eyeout of the field of vision. However, in some cases, a sudden increase in the number of these spots could be a warning symptom of a more serious eye condition, such as retinal detachment. This condition is characterized not only by an increase in floaters, but also by appearance of flashes of light on the sides of the field of visionor a partial loss of peripheral vision. Retinal detachment is a serious disease that must be treated as soon as possible, since, if not done, it can lead to complete loss of vision in the affected eye. If these symptoms suddenly appear, the recommendation is to go to a doctor without delay. ophthalmologist for a detailed evaluation.
Another factor that can contribute to the appearance of floaters is the so-called vitreous detachmentwhich happens when the vitreous gel separates from the retina. This situation is common from 60 years oldbut it can occur in younger people. Even though this detachment It is usually harmlessit is necessary to monitor it, since, in some cases, it can lead to a retinal tear. The American Society of Retina Specialists recommends an ophthalmological examination at least during the first months after noticing the appearance of these symptoms, especially to rule out any complications.
Other causes of ‘floaters’ in vision
There are also other causes of myodesopsias, less frequent but which can become serious. The eye inflammationcaused by infections either autoimmune diseasescan cause an increase in these floating spots, as well as trauma in the eye or tears in the retina. The diabetic retinopathya common complication in people with diabetes, can cause hemorrhages inside the eye, also creating these floating shadows. In cases more seriousthe presence of eye tumors They can alter the vitreous humor, generating these shadows in the visual field.
Although most eye floaters do not require specific treatment and tend to become less bothersome over time, it is important to be aware of changes in our vision. In cases where these stains significantly interfere with quality of lifethere are surgical treatments specific, such as vitrectomywhich eliminates vitreous humor and stains. However, these procedures are only performed when myodesopsias severely affect vision, since they also involve certain risks.
