Does this Quora answer imply that VCD (Vitreous Chamber Depth) can decrease?

Yes it is possible to theoretically shorten the eyeballs. This is because the eyeball is not a rigid, solid body. In fact, the eyeball is made of a fluid substance which, being a fluid, would adapt the shape of its container, which in this case is the sclera. The sclera is made of a tendon-like tissue with viscoelastic properties. As we know tendon tissue adapts to the load and functionality of the individual. Furthermore, research has demonstrated that the sclera is a dynamic tissue, capable of altering its ECM composition, its cellular phenotype, and its biomechanical properties in response to changes in the visual environment to regulate ocular size and refraction.

I am NOT asking about Axial Length here, as

Minor axial length shortening can happen because of the thickened choroid, corneal thinning (as it happens in ortho-k), etc. What rather matters is vitreous chamber depth not axial length and whether one can have sustained hyperopic shift as much as to reverse let's say 2D, 3D myopia over the long term and this is not observed in real life or human studies.
