Clinical Scorecard: Getting to the Root of Dry Eye Symptom Management With Nutrition

At a Glance

Key Highlights

• The Standard American Diet (SAD) is a major proinflammatory driver of meibomian gland dysfunction and DED.
• Specific nutrients such as vitamins A, C, D, B12, lutein, zeaxanthin, curcumin, omega-3 fatty acids, and gamma-linolenic acid support ocular surface health and reduce inflammation.
• Nutritional supplementation is an effective adjunct to topical therapies for managing dry eye symptoms and ocular surface inflammation.

Guideline-Based Recommendations

Diagnosis

• Recognize dry eye disease as a multifactorial inflammatory condition with symptoms impacting quality of life.
• Consider neurosensory abnormalities and neuropathic pain in patients with poor correlation between signs and symptoms.

Management

• Use topical therapies as mainstay treatment to disrupt ocular surface inflammation.
• Incorporate evidence-based nutritional supplementation targeting ocular surface support and inflammation reduction.
• Supplement with vitamin A to prevent goblet cell loss and corneal epitheliopathy.
• Use vitamin C for antioxidant, anti-inflammatory, and corneal wound repair benefits.
• Administer vitamin D to modulate immune response and reduce corneal inflammation.
• Include lutein and zeaxanthin to mitigate oxidative stress and regulate systemic inflammation.
• Consider curcumin to reduce reactive oxygen species and inflammatory mediators.
• Supplement omega-3 fatty acids to decrease inflammation, improve tear film quality, and promote corneal healing.
• Use gamma-linolenic acid (GLA) alongside omega-3s to ensure anti-inflammatory prostaglandin formation.
• Employ vitamin B12 supplementation to address neuropathic pain components of DED.

Monitoring & Follow-up

• Assess symptom improvement and ocular surface health following combined topical and nutritional interventions.
• Monitor serum vitamin D levels due to its association with DED occurrence.
• Evaluate neuropathic pain symptoms and response to vitamin B12 supplementation.

Risks

• Avoid GLA supplementation without concurrent omega-3 fatty acids to prevent proinflammatory conversion.
• Be aware of potential long-term vitamin A deficiency leading to corneal and conjunctival epithelial keratinization.

Patient & Prescribing Data

Adults with dry eye disease, including those with moderate-to-severe symptoms and neuropathic ocular pain

Nutritional supplementation combined with topical therapies improves ocular surface damage, reduces inflammation, enhances tear film quality, and alleviates neuropathic symptoms.

Clinical Best Practices

• Integrate nutritional assessment and counseling into dry eye disease management.
• Use a combination of topical anti-inflammatory therapies and targeted nutrient supplementation.
• Educate patients on the impact of diet, particularly reducing proinflammatory foods typical of the Standard American Diet.
• Consider professional resources such as the Ocular Wellness & Nutrition Society for clinician education on ocular nutrition.
