Specializes in Retinal Surgery

New floaters => exam: If theye are new onset, get an eye exam urgently. Floaters in the eye have several causes. The most common cause is degeneration of the vitreous fluid. The floaters gradually get worse, and persist. Sudden increase in floaters may be caused by vitreous separation (detachment) and may associated with a retinal tear or detachment, and an urgent eye exam is advisable. Thyroid has no relation.

No: Thyroid disease does not cause floaters.

Floaters: A posterior vitreous detachment causes floaters. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery.
