Ocular tissues, particularly the retina and optic nerve, are among the most metabolically active structures in the body and depend on an adequate supply of oxygen and micronutrients. In systemic medicine, dysnutritional states do not simply refer to calorie intake but to the overall biochemical “terrain” in which cells function. This is an interpretative perspective that complements, and never replaces, conventional ophthalmic assessment.

Within systemic frameworks, it is hypothesised that an imbalance in acid‑base homeostasis (a tendency towards increased tissue “acidity”) may be associated with a less favourable environment for metabolic exchanges. Emphasis is placed on lifestyle habits that support overall balance.

Oxidative stress
Oxidative stress describes a state in which reactive oxygen species exceed the body’s antioxidant defences. It is considered among the factors contributing to tissue ageing, including ocular structures. Systemic approaches pay attention to dietary antioxidant intake.

Micronutrient deficiencies
Vitamins, minerals, and essential fatty acids are involved in the proper function of ocular cells (such as the tear film and conjunctiva). Integrated approaches may take into account possible deficiencies, while specific diets remain the responsibility of qualified professionals.
From awareness to daily choices
Thinking in terms of dysnutritional states practically means paying attention to what supports or overloads tissues every day: diet, hydration, sleep quality, smoking, physical inactivity. Addressing these aspects does not replace ophthalmic treatment but may support general health and visual wellbeing.
Link with inflammatory profiles
In systemic medicine, nutritional and lifestyle imbalances are sometimes related to specific “inflammatory profiles” (phlogotypes), that is, characteristic ways in which the body responds. This link is intended as a descriptive and educational tool.
