Abstract
INTRODUCTION: Pseudoexfoliation syndrome (PES) is an age-related process associated with glaucoma and cataracts. It increases the risk of complications during cataract surgery. Blood neutrophil-to-lymphocyte ratio (NLR) is shown to be an effective biomarker of inflammation in PES. We aimed to investigate association of NLR and pseudoexfoliation (PEX) related cataract surgery complications. METHODS: A total of 210 eyes who underwent cataract surgery between January 2016 and January 2020 in our department were analyzed retrospectively. Patients were grouped with respect to developing complications and the two groups were compared. Medical records were reached to obtain neutrophil and lymphocyte values to calculate NLR. Data obtained were analyzed using chi-square test. Receiver operating characteristics curve analysis was performed to determine cutoff, sensitivity and specificity values. p value of ≤ 0.05 was considered statistically significant. RESULTS: The mean age was 68.1 ± 7.2 years and mean NLR was 2.11 ± 0.81. Complications were observed in 32 (15.2%) of the patients (group 1). Neutrophil counts (5.19 ± 0.64 vs. 4.43 ± 0.86, p < 0.001) and the NLR (2.68 ± 0.73 vs. 2.01 ± 0.81, p < 0.001) of group 1 were significantly higher than group 2. The ROC analysis revealed a cutoff value of 2.33 for NLR to predict cataract surgery complications with sensitivity of 87.5% and specificity of 78.1%. CONCLUSION: There is an association between NLR and increased risk of complications during cataract surgery in PES patients. NLR can be used as an easy method to help ophthalmologists in predicting the risks associated with cataract surgery in PEX eyes.
