Vitreous clouding is less related to glaucoma because it is mainly a degeneration of the vitreous body, a change from clear to opaque vitreous due to age or myopia. It usually does not have much effect on the aqueous humor circulation or vision. Glaucoma is mainly called glaucoma because of the increased intraocular pressure caused by the impaired aqueous humor circulation, which in turn leads to visual field and optic nerve damage. Glaucoma may have a narrowing of the atrial angle or a decrease in the aqueous filtration rate, but neither of these has much to do with vitreous clouding. Vitreous clouding does not aggravate the impairment of atrial fluid circulation or increase intraocular pressure, so even if there is vitreous clouding, the probability of having glaucoma is not high.
