Vitamin C is an effective adjunct in stabilizing IOP. Some individuals respond to as little as 2 grams a day of vitamin C, although others respond to only extremely high doses, for example, 35 grams a day. Because of the variance in the amount of vitamin C required to exert a positive effect, careful monitoring by a physician is required. Intravenous administration of vitamin C results in an even greater initial reduction. The pressure-lowering action of vitamin C is long-lasting if supplementation is continued, frequently showing an average reduction of 16 mmHg. Nearly normal tension levels have been achieved in some patients using vitamin C, when acetazolamide and pilocarpine therapy failed. The beneficial mechanisms by which vitamin C lowers inner eye pressure include (1) increased blood osmolarity, a process that draws fluid from the eye and into the blood, (2) diminished production of eye fluid, and (3) improved fluid outflow.

Many of the benefits of vitamin C are likely attributable to collagen formation, an important function of this water-soluble vitamin. Collagen is the most abundant protein in the body, including the eye, giving strength and integrity to ocular tissue. Vitamin C helps preserve the collagen in the eyes' drainage tubes, the very tubes that malfunction in glaucoma. Credits directed to vitamin C appear justified when considering reduced IOP and the improved structural health of the eye.
