ft yu, t hi of hathaye this way: the suspensory ligament of the lens separates the vitreou body from the aqueous humor. Suspensory ligament is formed from the hyaloid membrane. Hyaloid membrane forms zonule of Zinn and that contains suspensory ligament of lens. Anterior to the ligament is aqueous humor secreted by the ciliary body.

I think the vitreous/saline can diffuse through the ligament into the anterior/posterior chamber, which itself is anterior to the lens.

Vitreous cavity is not fully isolated. How do I know that? I know that people who get intermediate uveitis, one of the cardinal symptoms is floaters! Floaters are almost always due to shadows in vitreous (not aqueous because optics dont allow their shadows to form on retina). So this means vitreous is not "isolated" but things can go into it.

Look at anatomy of eye here, http://www.oakparkoptomet...ye-care/anatomy-a-vision

You can see clearly that ciliary body which produces aqueous is posterior to suspensory ligament as well and is in touch with vitreous.

Vitreous itself truly does not have a blood supply, but the retina it closely attaches to has rich blood supply and there is no doubt that chemicals/drugs can diffuse OUT of the blood vessels into the vitreous. My destroyed vitreous is almost certainly the RESULT of accutane that I took. Either due to direct effects on vitreous or indirect effects on retina, accutane has liquified some part of my vitreous, hence my floaters.

So I am positive that very small amounts of contraceptive or anti-depressive drugs DO enter the vitreous, vitreous is not a closed system. Another evidence is that after vitrectomy the saline is replaced by the aqueous because some part of clilary body which secrets the aqueous is posterior to the lens as well.

How do drugs entering the vitreous change collagen conformation? Easy. Electrostatic charges, changing solubulity product, changing protein confirmation etc etc, so many ways for these drugs to interact with the vitreous proteins and change their confirmation to form precipitates that we see as floaters.

Hope this helped.
My friend, I appreciate your reply. Before these things came, during 7 years I took an antidepressant to have some control over panic attacks, a small dose. I was even quitting when it appeared. First in one eye, 10 days later, in the other. Needless to say doctor prescribed an extra dose to help me in the first times - Some 4 months taking a quadruple dose and added xanax. Floaters stayed the same for 2 years. This year however I could notice some increase of amoeba-like strands, branching from the original floaters.

I know people who have taken tonnes of chemicals their whole life and have their vision clear. You have suspicions about Accutane. Sapiens mentioned SSRIs. But all we have is beliefs, we really don't know what's going in our eyes. Everyone I read has a personal explanation ranging from vitamins to computer monitors and I no longer know what to believe in. What do I have to change? Today I just talked with a friend and he told me has floaters and described them. In fact he doesn't care and even "enjoys playing with them". He never took anything besides beer and does not need glasses. I don't understand.

Maybe chemicals accelerated something, but as the time passes by, I feel that we would got these anyway. As the matter a fact, I remember squinting my eyes facing a lamp til when I was a kid and recall seeing things that looked like cells. When I do that now, all the floaters look just like those cells but now in clogged strands and balls. It's like these have always been here and now they clumped and I see them. 

FOV looks like the only practical hope.
I am sorry to say that you have to join our group of floater sufferers. Hope we can find the strength to deal with this/

You are right that each individual has his theories but think about if they make sense. How does staring at computer effect the vitreous?

The chemical theory is plausible. Accutane is known to effect rodes and cones of eyes, since it itself is a vit A derivative, it inhibits uptake of vitamin A in the eye. Moreover, doc told me to not eat vitamin A when taking accutane because it can cause overdose.

I used to have the perfect eyes in my family, we do not have any occular disease in family. Its only me who developed floaters AND 2 years after taking accutane, something is very wrong my friend. When I was taking accutane, my vision changed overnight, decreased night vision, flashes, but I never paid attention to these things since I was not paranoid about my health at that time.

I am of belief that accutane caused my floaters. I could be wrong, but this is the best explanation I have.

We saw it all pass by and you went by,
and I cant control anything.
When you said life cant be what you want ...
and I really want everything.
