Types of Floaters
Floaters are small pieces of debris that float in the eye’s vitreous humor. This debris casts shadows on to the retina (the light-sensitive tissue layer at the back of the eye). If you have floaters, it is these shadows that you see floating across your field of vision.
There are several different types of floater, including:
Most common in young people, this thin, dense floater can appear as multiple dots and/or string-like cobwebs and are a result of clumping of the collagen fibers of the vitreous. Depending on its size, and where it is located, it may be treatable with laser floater removal.
This cloud-like floater is caused by the natural aging process. Whilst this type of floater can sometimes be treated with laser floater removal, it often requires more overall treatment in order to obtain satisfactory results.
A Weiss Ring floater is a large, ring-shaped floater that forms as a result of PVD when the vitreous cortex pulls off the posterior wall, taking with it some of the fibrous vitreous cortex that surrounds the head of the optic nerve. This floater is usually located safely away from the crystalline lens and the retina and is fibrous. Because of this, it can be treated safely and effectively with laser floater removal.
