GONZALEZ, Timothy J.; PAEZ, Laura G.; CULMAN, Miguel A.  and  DURAN C., Sandra Carolina. Relationship between dry eye and Type 2 Diabetes Mellitus. Salud, Barranquilla [online]. 2023, vol.39, n.1, pp.206-227.  Epub Nov 18, 2023. ISSN 0120-5552.  https://doi.org/10.14482/sun.39.01.611.729.

Diabetes mellitus is a metabolic pathology that alters glucose levels in the body, being type 2 more prevalent, which can lead to modular systemic diseases that cause different metabolic disorders and cellular changes. Regarding ophthalmological alterations, diabetic retinopathy and dry eye can be highlighted, the latter being a chronic inflammatory condition causing damage to the ocular surface. Therefore, this review will provide information on the factors associated with the development of the dry eye in diabetes, highlighting changes in glycemia and the role of glucose metabolism on ocular structures such as the lacrimal gland, Meibomian glands, and the microvasculature, which can condition neuropathic disorders that lead to ocular symptoms, biological events such as changes in epigenetic expression, oxidative stress, and inflammation are prescribed, which presumably play an important role in diabetes and dry eye, for which the evaluation and analysis of tears in this population is done necessary, taking into account the changes in the ocular structures in diabetes and the new research on biomarkers of diabetes through the tear film.

Keywords : diabetes mellitus; dry eye; glucose; tear film; inflammation.
