In any case, the origin of floaters should always be determined by means of a thorough examination of the retina, so that conditions that might lead to retinal detachment can be ruled out. These floaters tend to disappear over time, as they deposit at the bottom of the eye because of gravity. In these cases, the mechanism is somewhat different, as the floaters usually derive from friction between the iris and the intraocular lens, which releases a fair amount of pigment inside the eye. Another situation in which tiny specks are often seen is after cataract surgery and/or laser capsulotomy. If you notice that the number of this type of floater suddenly increases, especially if they are associated with flashes, it may be a warning sign that a retinal tear has occurred. In such a situation, the patient should be evaluated by an eye specialist, as retinal tears can lead to the detachment of the retina.
These represent material that is released from the pigment epithelium behind the retina when a tear occurs.
However, tiny specks that are sometimes seen after flashing episodes in the eye should be observed closely. Most important, these shapes and figures are real (not imagined!) and may represent small condensations of the vitreous body that sometimes form clumps inside the eye. Floaters are more easily seen against a bright background, like the sky or a white wall. Floaters can have different shapes: some are tiny and speck-like others are large and slow moving. The presence of floaters is common in middle-aged individuals, particularly those who have conditions of the eye, such as nearsightedness, in which the vitreous body more frequently detaches from the retina. However, in the past year the number has actually increased! Is there anything I can do? I went to the ophthalmologist, and he said my eyes looked perfectly fine and that the floaters would probably go away with time. Last year I experienced a sudden onset of quite a large number of floaters. In any case, these flashes should be evaluated by an ophthalmologist to detect whether tears have occurred and to help you avoid further problems. Floaters result when pigment is released into the vitreous gel after a retinal tear develops. However, when tears occur, they are usually recognized by the patient because of the presence of floaters, several tiny black dots moving in the visual field. These tears can be dangerous if they are large because they can lead to retinal detachment. When the traction, or stretching, is strong enough, it can result in the vitreous gel's separating from the retina, with or without a retinal tear. Because the eye is the most active organ in the body, these flashes can occur very often.
Special neural receptors of the retina become activated when the stretching occurs, creating the sensation of flashing. When this happens, the areas where it adheres to the retina are stretched, especially with eye movement. With aging, the vitreous gel tends to liquefy, and this invariably reduces its volume. It naturally adheres to some areas of the retina (the layer of cells that lines the back of the eye). The vitreous body is the transparent gel that fills the posterior part of the eye. Another cause of flashing lights is vitreoretinal traction. If so, they can be treated with medications - a neurologist may be able to help with this. It is important to determine whether you have headaches after you see the image. While it is most likely not related to low blood sugar, it may be associated with many other diseases, including classic migraines. Someone told me it was related to low blood sugar, but I'm afraid it might be something worse. I see a flashing, brightly colored, jagged semicircle in the upper area of my eye - sometimes my left eye, sometimes my right. Several times during the past two weeks, I've had a strange occurrence in my eyes.
