Title: What is the vitreous humour in the eye, and where does it come from?
Post by: bafflezoo on 05/11/2005 15:00:43

I cannot find the answer to this.

I know that the ciliary body produces the aqueous humour in the eye, but I can't find where the vitreous humour is produced.

bafflezoo,

Strange that you asked this question at this time. I have just gone in for cataract surgery and removel of the vitreous jell from both eyes due to them both being full of appalling floaters.

The vitreous fluid or jelly if you like is produced by the inner eye. After the surgeon removed the vitreous fluid from my eyes that eyes refilled themselves minutes

Thus the eye produces the fluid inself, amazing!
Regards

Alan

Your eye did not replace your vitreous humour, your eye-surgeon did...

If floaters don't improve over time or significantly affect your vision,
an operation to replace the vitreous humour with saline (salt) solution may be considered.
This procedure is called vitrectomy.

A vitrectomy removes the vitreous humour, along with its floating debris, from the eye.
This is carried out after your eye has been numbed with a local anaesthetic.
The vitreous is replaced with a salt solution - as the vitreous humour is mostly water anyway, you won't notice any difference.

Then he lied to me and I cannot see why he should do this!!
