9. Muscae Volitantes
Commonly known as “flying flies” or “floaters”. These are deposits found in the clear gel that fills the eyeball. This gel is called the vitreous humour and it is the major substance in the eye.
The floaters suspended in the vitreous humour are only seen because of the shadow they cast on the retina. They appear as spots and wiggly lines. Floaters are caused by the shrinkage of the vitreous humour and other damage to the eye. The optometrist or ophthalmologist can see these floaters using instruments. The only treatment is surgery and this is reserved for very severe cases.
