Abstract

Objective: To evaluate corneal endothelial cell count and morphology according to senile nuclear cataract grade in patients with nuclear cataract. Material and Method: One hundred twenty three eyes of 90 patients and 26 eyes of 16 healthy volunteers were recruited in this study. All patients with nuclear cataract diagnosis were divided into 6 groups based on LOCS 3 classification. After detailed ophthalmologic examination, corneal endothelial cell count and morphology were assessed by using specular microscopy. The ANOVA test was used for comparison of endothelial cell density, variation coefficient, standard deviation and hexagonality values obtained from specular microscopy between the groups. A p value less than 0.05 was assessed as statistically significant. Results: The study included 26 healthy eyes, 20 eyes with grade 1 cataract, 23 eyes with grade 2 cataract, 25 eyes with grade 3 cataract, 26 eyes with grade 4 cataract, 15 eyes with grade 5 cataract and 14 eyes with grade 6 cataract. There was no statistically significant difference between the control group and the 6 cataract groups in measurements terms of age and gender (p=0.14 and p=0.21, respectively). The mean of endothelial cell count were as follows: control group: 2.321±265 cells/mm2 (1.900-2.925 cells/mm2), grade 1 cataract group: 2.431±278 cells /mm2 (1.982-2.820 cells/mm2), grade 2 cataract group: 2.428 ± 357 cells/mm2 (1.920-2.991 cells/mm2), grade 3 cataract group: 2.369±352 cells/mm2 (1.795-2.696 cells/mm2), grade 4 cataract group: 2.540 ± 294 cells/mm2 (1.890-2.797 cells/mm2), grade 5 cataract group: 2.311±341 cells/mm2 (1.890-2.425 cells/mm2) and grade 6 cataract group: 2.294 ± 345 cells/mm2 (1.958-2.529 cells/mm2). There was no statistically significant difference between the groups (p=0.40). No significant difference was observed in the coefficient of variation, standard deviation and hexagonality between the groups (p=0.55, 0.49, 0.85, respectively). Conclusion: In this study, significant difference in endothelial cell density and morphology were not found between different cataract grades. This result might be related with different mechanisms and pathways causing oxidative damage in cornea and lens although the oxidative damage is responsible for pathological progresses in both tissues. The studies investigating this issue with longer follow-up are needed.

Özet

Amaç: Nükleer kataraktı bulunan hastalarda kataraktın evresine göre kornea endotel sayı ve morfolojisini değerlendirmektir. Gereç ve Yöntem: Çalışmaya 90 hastanın 123 gözü ve 16 sağlıklı gönüllünün 26 gözü dahil edildi. Çalışmaya alınan katarakt tanısı olan tüm hastalar LOCS 3 sınıflamasına göre 6 gruba ayrıldı. Detaylı oftalmolojik muayene sonrası endotel hücre sayısı ve morfolojisi speküler mikroskopi ile değerlendirildi. Speküler mikroskopiden elde edilen endotel hücre sayısı, varyasyon katsayısı, standart sapma ve heksagonalite değerleri gruplar arasında ANOVA testi ile kıyaslandı. p<0,05 değeri istatistiksel olarak anlamlı kabul edildi. Bulgular: Kontrol grubu 26 göz, Evre 1 katarakt grubu 20 göz, Evre 2 katarakt grubu 23 göz, Evre 3 katarakt grubu 25 göz, Evre 4 katarakt grubu 26 göz, Evre 5 katarakt grubu 15 göz, Evre 6 katarakt grubu 14 gözü kapsıyordu. Kontrol grubu ve 6 katarakt grubu arasında yaş ve cinsiyet bakımından istatistiksel olarak anlamlı fark yoktu (yaş ve cinsiyet için sırasıyla p=0,14 ve p=0,21). Ortalama endotel sayısı gruplara göre aşağıdaki şekildeydi: Kontrol grubu: 2,321±265 hücre/mm2 (1,900-2,925 hücre/mm2), Evre 1 katarakt grubu: 2,431±278 hücre/mm2 (1,982-2,820 hücre/mm2), Evre 2 katarakt grubu: 2.428±357 hücre/mm2 (1,920-2,991 hücre/mm2), Evre 3 katarakt grubu: 2,369±352 hücre/mm2 (1,795-2,696 hücre/mm2), Evre 4 katarakt grubu: 2,540±294 hücre/mm2 (1,890-2,797) hücre/mm2), Evre 5 katarakt grubu: 2,311±341 hücre/mm2 (1,890-2,425 hücre/mm2), Evre 6 katarakt grubu: 2,294±345 hücre/mm2 (1,958-2,529 hücre/mm2). Gruplar arasında istatistiksel olarak anlamlı fark yoktu (p=0,40). Gruplar arasında varyasyon katsayısı, standart sapma ve heksagonalite ölçümlerinde anlamlı fark gözlenmedi (sırasıyla p=0,55, 0,49, 0,85). Sonuç: Bu çalışma sonucunda nükleer kataraktın farklı evreleri arasında endotel hücre sayısı ve morfolojisinde istatistiksel olarak anlamlı fark saptanmadı. Bu sonucumuz her iki dokunun patolojik gelişmelerinde oksidatif hasar sorumlu olsa da, oksidatif hasara yol açan mekanizmaların ve yolların farklı olmasından kaynaklanıyor olabilir. Bu konuyu araştıran daha uzun takip süreli çalışmalara ihtiyaç vardır.
