The end of age in combination with certain diseases (e.g., diabetes, rheumatoid arthritis), makes the vitreous body of the eye to degenerate [i.e. to shrink or grow in volume] thus formed concentrations in the eye, in the form bands or spots.
By moving the eye, the fluidized this vitreous moves gradually away from the back of the eye to be detached from the retina and optic nerve (posterior vitreous detachment). Posterior vitreous detachment that, as a result of degeneration of the vitreous age related, are common in people over 60 years. In people with high myopia occurs at a younger age because the vitreous in such cases degenerates earlier.
phenomenon symptoms:
- Showing black dots of varying sizes (fly flies).
- Showing blurring the cobweb form to move with the eyeball movements.
- Show called butterflies or large black floating spots. But special attention should be paid since these symptoms may be due to some pathological and dangerous for vision conditions such as crack (tear) and retinal detachment. In this case you should immediately visit your ophthalmologist.
Is there a cure?
In the case of posterior vitreous detachment there is no cure. The detachment is usually permanent and symptoms of myopsion and phosphenes can we and forever. The vitreous concentrations tend to move towards the front of the eye and possibly symptoms attenuate with time.
A patient with vitreous detachment, however, may suffer and retinal detachment. Due to lack of mechanical pressure to the point of detachment or drafts created, we must be careful especially in the first month. We should not bend sharply to lift many weights or make sudden movements. If symptoms worsen need to urgently visit our eye doctor to see if something has changed.
Conversely, if diagnosed with a crack in the retina then it should urgently become laser in order to entrenched the area and does not lead to complete detachment. In the case of retinal detachment, the only solution is surgical restoration. However, these cases are less frequent.
