There is evidence that proton pump inhibitors (PPIs) might decrease vitamin C levels in the body. A study showed that even a short course of omeprazole, a common PPI, reduced vitamin C levels in healthy volunteers, regardless of their dietary intake. This suggests that PPIs may reduce the bioavailability of vitamin C, meaning the body has a harder time absorbing and using it. Vitamin C plays a crucial role in immune function and antioxidant defenses and therefore individuals using PPI therapy should consider supplementation with vitamin C to protect against a deficiency.

Vitamin C deficiency weakens collagen in capillary and vascular walls, so severe scurvy can present with ocular hemorrhages in the conjunctiva and retina that threaten vision if not treated. Case reports and small series describe retinal hemorrhages, flame‑shaped hemorrhages, and even retrobulbar bleeding compressing the optic nerve, which can lead to optic neuropathy and visual loss in advanced cases. The encouraging point is that, when vitamin C deficiency is recognized early and promptly repleted, many ocular hemorrhages and visual symptoms can partially or fully resolve, making it critical to consider vitamin C status in patients with otherwise unexplained ocular bleeding and visual complaints.
