It is a degenerative thinning of the sclera, causing the vitreous humour to slightly bulge through it, giving the eye large blackish lumps.
scleromalacia
This varies depending on the health and age of the eyeball.Eyes with degenerative conditions, such as keratoconus, or scleromalacia perforans can be 'popped' all too easily.Pressure against the eye is never a good thing, and sustained or repeated pressure should be avoided, even if far below the level at which rupture is possible.Impact from a squash ball has the potential to tear parts of the eyeball, and to dislodge other parts.
