Myodesopsia or eye floaters
In most cases, myodesopsia are a consequence of a natural aging process due to the vitreous humor’s loss of water and volume. Although the floaters seem to be in front of your eye, they are actually moving inside it, and what we perceive is their shadows.
7 out of 10 people suffer from myodesopsia at some point in their life.Dr. Luis Alonso | Ophthalmologist
Myodesopsia are also related to diabetes as it affects the vitreous humor and the retina, just as they are to any other disorder which directly or indirectly affects these structures.
Myodesopsia are usually innocuous and harmless and do not affect vision. However, in some situations, eye floaters can be much more than just small vitreous disturbances as if they are very dense they can cause blurred vision, and in some cases, they may be related to ocular pathologies such as uveitis, vitreous hemorrage or retinal detachment.
Contact an ophthalmologist promptly if you notice a sudden increase of floaters, if flashes of light (photopsia) appear, if they stop moving when you move your eyes or significantly change size. Fundus eye examination will be carried out in order to examine the retina and determine whether any serious pathology exists.
In the cases where the amount and size of the floaters is very small, patients tend to get used to them within a few months, so no treatment is required. In the cases where myodesopsia limit the patient’s vision, the following treatments are available:
Vitreolysis is a YAG laser based treatment to remove myodesopsia. Floaters are the laser’s target, which uses tens of pulses to destroy them. Microfragmentation of the vitreous opacities will avoid them from significantly affecting the patient's vision. This treatment’s goal is to achieve a visual functional improvement, allowing the patient to carry out his day-to-day activities.
Vitrectomy is an eye surgery in which the vitreous humor inside the eye (where the opacities or myodesopsia are found) is replaced by a sterile saline solution. It is an invasive procedure which is not free of risks, being therefore considered as the last treatment option in severe vision loss cases.
This procedure involves the use of intravitreal drugs which have a liquefying effect on the vitreous humor. It can be used before vitrectomy surgery in order to simplify it and in some cases it has been exclusively used as a treatment for myodesopsia.
Our first recommendation is always to ignore myodesopsia, even if it is complicated.Dr. Fernanda García | Ophthalmologist
