The number of patients with diabetes mellitus in the Russian Federation on January 1, 2019 is more than 4.5 million people, which is 3.12% of the population of the Russian Federation. Metabolic disorders in diabetes mellitus cause physicochemical changes, including a violation of acid-base balance (pH). Aim. To study the effect of diabetes mellitus and ocular prosthetics on the acid-base balance of the prosthetic cavity. Materials and methods. From 2018 to 2021 - 185 patients of both sexes from 21 to 80 years old (57.73±17.34 years old) were examined. 47 patients using an eye prosthesis and without diabetes mellitus (group I); 93 patients using an eye prosthesis with diabetes (group II), which were divided into two subgroups depending on the level of glycated hemoglobin (HbA1c): II-a subgroup - 47 patients with HbA1c up to 7.5%, II-b group – 46 patients with HbA1c more than 7.5%; 45 patients, without an eye prosthesis and without diabetes mellitus (group III). Results. In patients with an ocular prosthesis and without diabetes, a shift in pH to the side of acidosis was observed. In patients with an ocular prosthesis and with diabetes mellitus, the greatest shift in the pH of the conjunctival cavity to the side of acidosis, depending on the level of HbA1c (8-8.5 – in 25.8% of cases, 9-9.5 – in 43% of cases, and <10 – in 31.2% of cases). Conclusions. The presence of an ocular prosthesis in the conjunctival cavity leads to a shift in pH to the side of the alkaline side. The progression of the pH shift to the side of acidosis directly depends on the HbA1c level in patients, and the combination of two factors (the use of an ocular prosthesis in the conjunctival cavity and the presence of diabetes in the anamnesis) leads to an aggressive shift in the pH of the conjunctival cavity to the side of acidosis. Key words: acid-base balance, ocular prosthesis, diabetes mellitus.
