Notice
The definitions in this glossary are for educational purposes only. Concepts such as phlogotype, dysnutritional states, microbiota, inflammaging, and PNEI refer to interpretative models used in systemic/integrative medicine and do not replace official guidelines, therapeutic protocols, or the opinion of your physician.
Some of the terms used in systemic medicine and on this website are not part of traditional medical language. They are briefly presented here in a descriptive way, solely to help readers understand the informational content.
Phlogotype
In systemic medicine, “phlogotype” is used to describe a possible individual inflammatory profile, that is, how an organism tends to react to and maintain inflammatory processes over time (for example, more prone to acute, chronic, or low‑grade inflammation). It is a conceptual model rather than a formal diagnosis.
Use on this site: References to phlogotype are meant only to illustrate why different people may show different inflammatory manifestations, including at ocular level, even when exposed to similar risk factors.
Dysnutritional states
In systemic frameworks, “dysnutritional states” denote conditions in which nutrient intake or handling by the body is not optimal (for example micronutrient imbalance, increased oxidative burden, or acid‑base imbalance). The term does not replace official nutritional classifications but offers a practical shorthand.
Within this site: Mentioning dysnutritional states highlights the potential contribution of diet and lifestyle to overall wellbeing, including that of ocular tissues, without proposing dietary protocols as alternatives to those recommended by physicians or nutritionists.
Gut microbiota
The gut microbiota is the community of microorganisms (bacteria, viruses, fungi) that live in the intestinal tract. It is widely studied for its role in metabolism, barrier function, and immune modulation.
Links with the eye: Some studies suggest indirect connections between dysbiosis (altered microbiota) and systemic inflammatory conditions that might also affect ocular tissues. These associations are still being investigated and do not replace established aetiological explanations of eye diseases.
PNEI (Psycho‑Neuro‑Endocrine‑Immunology)
PNEI explores the interactions between the nervous system, endocrine system, immune system, and psychological domain, assuming constant bidirectional communication among them.
Interpretative angle: From this perspective, the eye is considered sensitive to neuro‑hormonal and stress‑related factors, while conventional ophthalmic causes and evidence‑based treatments remain central.
Extracellular matrix (ECM)
The extracellular matrix is the structure made up of proteins, glycoproteins, and other molecules surrounding cells, providing support and helping regulate exchanges. In systemic medicine it is often described as a tissue “environment” that may influence organ function.
Theoretical relevance: References to the extracellular matrix on this site aim to illustrate, in qualitative terms, how the tissue micro‑environment can be considered in broader reflections on ocular health, without proposing specific tests or treatments targeting this single component.
Inflammaging
“Inflammaging” is a term used in the literature to describe the association between ageing and chronic low‑grade inflammation. It is widely discussed in the field of healthy ageing research.
Ocular ageing: On this site, the term is used to explain in general how managing systemic risk factors may also influence ocular structures typically affected by age (such as lens and retina), without replacing classical explanations of diseases like cataract or age‑related macular degeneration.
Exposome
The “exposome” refers to the sum of environmental and lifestyle exposures over a lifetime (for example pollutants, light, diet, habits) considered in relation to health and disease.
Preventive implications: Mentioning the exposome emphasises the importance of well‑known preventive measures (protection from intense light, smoking cessation, balanced diet, etc.), which are consistent with general and ocular health recommendations.
Oxidative stress
Oxidative stress describes an imbalance between the production of reactive oxygen species and the body’s antioxidant defences. It is a well‑established concept in biology and medicine.
Role in eye health: Oxidative stress is regarded as one of several factors involved in ageing of ocular tissues and in the pathogenesis of certain diseases (such as cataract and some forms of macular degeneration) within multifactorial frameworks that always require specialist assessment.
