Myodesopsy

The myodésopsies (otherwise called floating bodies or flying flies) are defined as images which appear in the field of vision, in particular on a clear bottom, they are the fact of suspended and positioned opacities, often extremely inconveniently, in the vitreous body.

General information

The myodésopsies are frequent and are not, in general, causes doctor visit. They are generally very few and do not gènent the daily activity.

The myodésopsies are increasingly frequent with the age. However, occurred to them brutal or the increase in their number can require the opinion of a specialist (ophtalmologist).

To date, medicine does not consider this ocular disorder a true pathology, but a benign symptom and without gravity. In fact, there is not, currently, of medical studies having for object the discovery of effective and noninvasive therapies.

Origin

The myodésopsies find their origin in nonthe homogeneity of the Corps glazed of the eye. When the light crosses the Corps glazed, it is possible that it meets microscopic particles which will project their shade on the Rétine. These particles float in the gelatinous substance which is the Corps glazed, thus the movement of the eye involves their movement in shift or in a synchronous way, which has as a consequence connect it incapacity to focus the glance on them.

But, in the worst of the cases, opacities follow the course of the glance, causing very heavy problems of concentration then sometimes

Several causes seem at the origin of this ocular disorder, but the only common point which to date seems to be essential in a rather constant and regular way is the fact that before the appearance of the myodésopsies almost all the people would have undergone a very large stress.

Physiopathology

The increase in the number of myodésopsies or their brutal appearance must make seek anomalies of the elasticity of glazed.

Possible treatment

No treatment exists to make disappear the myodésopsies (except the vitrectomy or, better, the FOV). For the marked and round myodésopsies, there exists a laser treatment little known (one of the criteria of admissibility for this treatment is that the ophtalmologist can " voir" opacities easily). In addition, except in very rare cases, they do not disappear from themselves.

They must however allow the description by the Ophtalmologiste of an associated disorder (beginning of Décollement of retina, Glaucome, Hypertension intraocculaire…).

Famous cases

The painter Edvard Munch was reached of myodésopsies consecutive to a hemorrhage of the Corps glazed.
