Which dietary supplement is listed as a potential adjunct in dry eye management?

• A. Vitamin D
• B. Omega-3 supplements
• C. Zinc
• D. Probiotics

Answer: (B)

Dietary supplementation can support dry eye management by modulating inflammation and the tear film. Omega-3 fatty acids, especially EPA and DHA, have anti-inflammatory effects that can improve meibomian gland function and help stabilize the tear film. Clinically, they have been associated with modest improvements in tear breakup time and patient symptoms in some studies, though results vary and long-term outcomes are still being explored. This inflammatory-targeted approach fits dry eye management, where reducing ocular surface inflammation can lessen symptoms and improve tear quality.

Other options listed don’t have as consistent or robust evidence for this purpose. Vitamin D shows mixed associations with ocular surface disease and isn’t routinely relied upon as an adjunct for dry eye. Zinc plays a role in ocular health but isn’t established as an adjunct specifically for dry eye management. Probiotics have limited and less consistent data in this area. Thus, omega-3 supplements are the best-supported adjunct among these choices.
