Estimation of lacrimal dysfunction indices in patients with recurrent pterygium

The rationale of the research is driven by the severity of dry eye syndrome (DES) in the pterygium recurrencies development as well as by the necessity to investigate tear dysfunction and methods for its optimal correction in this patient population. Purpose of the study. To assess the impact of tear dysfunction indices on the development of recurrent pterygium. Materials and methods. We observed 60 patients (67 eyes) with recurrent pterygium. Patients were divided into four observation groups depending on the number of recurrencies. In order to study the dynamics of the DES manifestations during the postoperative period, pathogenetic therapy was used, which included a tear fluid substitute. All patients underwent a comprehensive assessment of subjective and objective DES indices before and after surgery. Results. A positive dynamics of subjective manifestations and objective indices of DES under the action of a tear substitute after surgery was reliably confirmed. A decrease in the number of patients with type III and IV crystallization after surgery was confirmed. Conclusion. The obtained data indicate an increase in the mucin content in the tear fluid composition, which leads to a stabilization of the tear film and to a decrease in the DES intensity.
