Abstract

Purpose: To investigate the effects of cataract extraction on SITA perimetry in primary open angle glaucoma (POAG) patients with a glaucomatous visual field defect. Materials and Methods: Twenty three eyes of 16 POAG patients who had uncomplicated cataract surgery with phacoemulsification between 2005 and 2009 were included in this retrospective study. Best corrected visual acuity (BCVA) was measured with the Snellen test, intraocular pressure was measured with Goldmann tonometry and the visual field was analyzed with the SITA-Standard 24-2 test at the Humphrey visual field analyzer, both preoperatively and postoperatively. Visual field parameters, MD (Mean deviation) and PSD (pattern standard deviation) were also recorded. Results: The mean BCVA value of the patients was 0.25±1.72 (0.05-0.7) preoperatively and 0.74±0.25 (0.3-1) postoperatively. Postoperative BCVA was significantly better than preoperative BCVA (p=0.0001). The preoperative mean MD value was -8.56±5.42 (-3.17--24.77) and mean PSD value was 5.03±3.36 (1.81-14.31). Postoperatively these values were -6.41±4.04 (-1.41--20.33) and 4.76±2.43 (1.53-9.57) respectively. The mean postoperative MD value was significantly better than the postoperative one (p=0.002) although PSD values showed no significant difference (p=0.681). Conclusion: PSD is considered to be a more reliable parameter in the glaucoma follow up of patients with cataract, as we observed a considerable improvement in the MD in conjunction with increased BCVA after cataract surgery of the patients who had cataract and PAAG, whereas the PSD value remained unchanged.

Özet

Amaç: Glokomatöz görme alanı kaybı olan primer açık açılı glokomlu (PAAG) olgularda katarakt ekstraksiyonun SITA standart görme alanı üzerindeki etkilerini araştırmak. Gereç ve Yöntem: Komplikasyonsuz fakoemulsifikasyon yöntemi ile katarakt ameliyatı geçirmiş PAAG’lu 16 olgunun 23 gözü çalışma kapsamına alındı. Olguların ameliyat öncesi ve ameliyat sonrası Snellen testi ile en iyi düzeltilmiş görme keskinliği (EDGK) ve Goldmann tonometri ile göz içi basınçları ölçülerek Humphrey otomatize görme alanı ile SITA-Standart 24-2 testi kullanılarak görme alanı ölçümleri yapıldı. Görme alanı ölçümlerinden hesaplanan MD (ortalama sapma) ve PSD (desen standart sapma) değerleri kaydedildi. Bulgular: Olguların ameliyat öncesi EDGK değerlerinin ortalaması 0.25±1.72 (min. 0.05 max. 0.7) olup ameliyat sonrası dönemde ortalama EDGK 0.74±0.25 (min. 0.3 max 1) di. EDGK değerlerinin ameliyat öncesi ve ameliyat sonrası dönemdeki ortalamaları karşılaştırıldığında istatistiksel olarak anlamlı fark vardı (p=0.0001). Ameliyat öncesi görme alanı ölçümlerinde ortalama MD değerleri -8.56±5.42 (-3.17-24.77) ve PSD değerleri ise 5.03±3.36 (1.81-14.31) idi. Bu değerlerin ameliyat sonrası ortalama değerleri sırasıyla -6.41±4.04 (-1.41--20.33) ve 4.76±2.43 (1.53-9.57) idi. Ameliyat öncesi ve ameliyat sonrası MD değerleri karşılaştırıldığında aralarında istatistiki olarak anlamlı fark varken (p=0.002) PSD değerlerinin karşılaştırılmasında iki grup arasında anlamlı bir fark bulunamadı (p=0.681). Sonuç: Katarakt ile birlikte PAAG olan olgularda katarakt ameliyatından sonra artan EDGK’ ne bağlı olarak MD de belirgin bir iyileşme izlenirken, PSD değerinde bir değişiklik izlenmediğinden, kataraktlı olguların glokom takibinde PSD’nin daha güvenilir bir parametre olduğunu düşünmekteyiz.
