Abstract

Purpose: To investigate the total oxidant status (TOS), total antioxidant capacity (TAC) and oxidative stress index (OSI) of the aqueous humor and serum in patients with mature and immature senile cataract.Materials and Methods: Cataract surgery patients (n=34) were enrolled in the study. We included 17 patients with mature cataracts (Group 1) and 17 patients with immature cataracts (Group 2). Samples of the aqueous humor and serum were taken from all patients and measured spectrophotometrically. Serum and aqueous TOS, TAC and OSI levels were compared in the two groups. The Kolmogorov-Smirnov test and Mann-Whitney U test were used for statistical analyses.Results: The mean TOS level in Group 1 and 2 patients was 508.7 ± 45.9 and 245.6 ± 15.8, respectively, which is a statistically significant difference (p=0.0001). The mean TAC level in Group 1 and 2 was 2.28 ± 0.6 and 3.83 ± 2.1, respectively. This difference was statistically significant (p=0.005). The mean OSI in Group 1 and 2 was 13.9 ± 4.1 and 10.4 ± 1.4, respectively, with the mean OSI level statistically higher in Group 1 (p=0.005). The differences in mean TOS, TAC and OSI levels in the serum were not statistically significant.Conclusion: The aqueous humor of mature cataract patients is characterised by increased oxidative stress and decreased antioxidant capacity. The increased oxidative stress may play a significant role in the pathogenesis and maturation of senile cataracts.

Özet

Amaç: Matür ve immatür senil kataraktlı hastaların serum ve aköz humörlerinde total oksidatif durum (TOS), total antioksidan kapasite (TAC), oksidatif stres indeksi (OSI) değerlerini araştırmak.Gereç ve Yöntemler: Katarakt cerrahisi yapılan 34 hasta çalışmaya dahil edildi. Hastalar matür (Grup 1, n=17) ve immatür (Grup 2, n=17) kataraktlı olmak üzere 2 gruba ayrıldı. Tüm hastalardan serum ve aköz humör örnekleri alındı ve spektrofotometrik olarak ölçüldü. Serum ve aköz TOS, TAC ve OSI değerleri 2 grup arasında karşılaştırıldı. İstatistiksel analiz için Kolmogorov-Smirnov testi ve Mann-Whitney U testi kullanıldı.Bulgular: Ortalama TOS değeri grup 1 ve 2'de sırasıyla 508.7 ± 45.9 ve 245.6 ± 15.8 olup aradaki fark istatistiksel olarak anlamlıydı (p=0.0001). Ortalama TAC değeri Grup 1'de 2.28 ± 0.6 , Grup 2'de 3.83 ± 2.1 olup, istatistiksel anlamlılık saptandı (p=0,005). Ortalama OSI değeri ise Grup 1 ve 2'de sırasıyla 13.9 ± 4.1 ve 10.4 ± 1.4 bulundu ve Grup 1 de OSI değeri istatistiksel olarak daha yüksekti (p=0.005). Serum TOS, TAC ve OSI değerleri gruplar arasında istatistiksel olarak farklı değildi.Sonuç: Matür kataraktlı hastaların aköz humörleri artmış oksidatif stres ve azalmış antioksidan kapasite ile karakterizedir. Artmış oksidatif stresin senil katarakt patogenez ve matürasyonunda rolü olduğunu düşünmekteyiz.
