Conclusion: Although the differences between treatment groups are not statistically significant, we conclude that SLT is effective in patients who had been treated by ALT, but the effect of SLT is inversely proportional to the range of the area previously treated by ALT.

Abstract

Aim: To compare the effectiveness of SLT in patients who had a previous ALT treatment with patients without a history of ALT. Materials and Methods: 208 eyes of 166 patients were divided into 3 major groups according to having a previous ALT treatment or not.Group A: no previous ALT, Group B: previous 180° ALT, Group C: previous 360° ALT. The major groups, then re-categorized according to the quadrantal relationship of the previous ALT and recent SLT procedures. Statistical evaluations were done by using ANOVA and t-tests.Results: Within the major groupings, A,B and C are similar in mean follow-up and in baseline IOP. However they differ in the mean change in IOP, that being -5.5, -4.4 and -3.5 mmHg respectively. Conclusion: Although the differences between treatment groups are not statistically significant, we conclude that SLT is effective in patients who had been treated by ALT, but the effect of SLT is inversely proportional to the range of the area previously treated by ALT.

Özet

Amaç: İlk kez SLT tedavisi uygulanmış olgular ile, daha önceden ALT tedavisi görmesine rağmen göziçi basınç (GİB) yüksekliği nedeniyle SLT ile yeniden tedavi edilen olgular karşılaştırılmıştır. Yöntem: Çalışma kapsamına 208 göz alınmıştır. Olgular primer olarak SLT yapılanlar (Grup A) önceden 180° ALT uygulananlar (Grup B) ve önceden 360° derece ALT uygulananlar (Grup C) olmak üzere üç grupta karşılaştırılmıştır. Bu 3 ana grup yine SLT yapılan kadran miktarı ve bölgesi göz önünde tutularak, alt gruplara ayrılmıştır. Son muayenede ameliyat öncesi ortalama GİB düzeylerinden farklılığı saptamak için t-testleri, gruplararası karşılaştırma için ANOVA testi uygulanmıştır. Bulgular: A, B ve C ana gruplar, ortalama izlem süresi ve ameliyat öncesi ortalama GİB değerleri açısından eşdeğer bulunmuştur. Ancak ameliyat sonrası ortalama GİB değişiklik değeri sırasıyla ; -5.5 mmHg, -4.4 mmHg ve -3.5 mmHg olarak farklılık göstermiştir. Tartışma: Gruplararası farklılık istatistiksel olarak anlamlı olmamakla beraber, SLT'nin ALT uygulanmış trabeküler alanda da GİB düşüklüğü oluşturabilecek etkinliğe sahip olduğunu ancak bu etkinliğin ALT uygulanmış alan arttıkça, azaldığını düşünmekteyiz.
