Evaluation of Ocular Surface Parameters and Systemic Inflammatory Biomarkers in Hazelnut Harvesters.

Abstract

Aim: To assess the relationship between systemic inflammation markers and ocular surface parameters in hazelnut harvesters.

Material and method: This prospective study included 30 patients presenting with moderate ocular surface diseases during the hazelnut harvesting season. A detailed ophthalmological examination was performed during the harvesting season and the first month after the end of treatment (control). Schirmer test, tear break-up time (TBUT), and ocular surface disease index (OSDI) scores were determined. In complete blood count analysis, in addition to the evaluation of inflammatory cells, the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) were calculated.

Results: Eosinophil percentage had a high level of negative correlation with the TBUT and Schirmer values and a high level of positive correlation with the OSDI score during the hazelnut picking season (r = -0.727, r = -0.735, r = 0.750, respectively). During the hazelnut harvesting season, the NLR and SII parameters had a moderate level of negative correlation with the TBUT (r = -0.29 and r = -0.276) and Schirmer (r = -0.33 and r = -0.298) values and a moderate level of positive correlation with the OSDI score (r = 0.389 and r = 0.264).

Conclusion: In hazelnut harvesters, ocular allergy and inflammation may be associated with systemic biomarkers.
