Abstract

The research is devoted to the in vitro study of the behavior of the model system «irrigation balanced salt solution BSS − H2O» in order to further develop treatment, rehabilitation and prevention measures for patients with ophthalmic diseases. The aim of the investigation is the experimental determination and analysis of physico-chemical properties of irrigated balanced salt solution, the study of its behavior in the aquatic environment to model changes in the characteristics of intraocular fluid and further development of rehabilitation and preventive measures for ophthalmic patients. Materials and Methods. The study used methods of physico-chemical analysis, in particular, densimetry and viscosimetry of model systems containing BSS for intraocular use and double-distilled water in different volume ratios. The density of the system was determined pycnometrically (20.00 0С ± 0.05 0С; 101.3 kPa); the correction for weight loss of bodies in the air has been taken into account. Viscosity was measured under the same conditions with an Ostwald viscometer. Statistical analysis and evaluation of the reliability of the results were performed using such software products as MS Excel 2007, Google Spreadsheets, SPSS Statistics. Results. Approximate mathematical models of the dependences of density and kinematic and dynamic viscosity on the composition of the multicomponent system «BSS – H2O» were obtained with quite high coefficients of determination. Statistical significance and adequacy of model selection were tested by Student's criterion at a significance level of 5 %. To develop therapeutic, prophylactic and rehabilitation measures, mathematical models of kinematic and dynamic viscosity dependences on the density of the «BSS – H2O» system, measured under the same conditions, were built. The models also have high coefficients of determination. Conclusion. The in vitro physico-chemical analysis of the system «BSS – H2O», as well as the obtained approximate mathematical models can be used to predict possible changes in the characteristics of irrigated balanced salt solution during its long stay in the patient's eye.
