To study the effect of pH on the conjunctival cavity. Materials and methods. All patients underwent the following studies: Biomicroscopy of the conjunctival cavity, evaluation of the cosmetic effect of prosthetics, sensation and comfort, and bacterial culture of the discharge. The results of the study. As a result of the study, it was found that patients using ocular prostheses with concomitant diabetes mellitus have a pH shift in the conjunctival cavity to the alkaline side, which will lead to partial inflammatory reactions of the conjunctival cavity, resulting in a decrease in the desired cosmetic effect Conclusion. Diabetic patients require a lot of attention and a more thorough approach to meeting the conditions for normalizing the pH of the conjunctival cavity, and the terms of replacing the prosthesis, as a result, achieving a good cosmetic effect.

One of the important medical and social problems in patients with anophthalmos today is the elimination of a cosmetic defect [3,7].The eye prosthesis has not only cosmetic, but also therapeutic and prophylactic value, protecting the eye cavity from the irritating effect of environmental factors. Prolonged absence of a prosthesis in the conjunctival cavity causes a chronic inflammatory process and its reduction [2,4,8]. The aim of the study: To improve the functional and cosmetic effect of ocular prosthetics in patients with anophthalmos and subatrophy. Materials and methods: Ophthalmological, electron microscopic, laboratory research methods were used in the work. Conclusions: Primary ocular prosthetics should be carried out within the first month after surgery. The presence of an adequate musculoskeletal stump provides high results of the cosmetic effect of ocular prosthetics. Individual ocular prosthetics is the most optimal type of prosthetics, which achieves the expected cosmetic and functional results.

The aim of the study was to study the effect of wearing an eye prosthesis by patients with type 2 diabetes on the level of acid-base balance of the conjunctival cavity. Materials and methods. Biomicroscopy of the conjunctival cavity, the pH of the discharge from the conjunctival cavity and HbA1c in the blood were determined. Conclusions. The constant presence of an ocular prosthesis in the conjunctival cavity leads to a shift in the acid-base balance to the alkaline side, and the patient's history of diabetes also leads to the same result. The shift in the pH of the conjunctival cavity directly depends on the level of glycated hemoglobin, and the combination of these factors leads to a more aggressive shift of the pH to the alkaline side.
