Floaters are deposits of different sizes and shapes within the eye’s vitreous humour which is normally transparent. The common type of floater is due to changes in the vitreous humour, its natural ageing process.
This vitreous debris casts shadows on the retina, and it is the shadow that is visible to you. Other serious causes of floaters, blood in vitreous, pigment in vitreous. This will present with associated symptoms of flashes, curtain vision loss etc.
Call health care provider if floaters present with flashes and or vision loss. This could indicate vitreous/Retinal detachment.
Photopsia is the presence of perceived flashes of light.
Common causes: Posterior vitreous detachment, Retinal break or detachment, and migraine.
Call health care provider if flashes present with vision loss.
