Abstract

Purpose: To investigate the effects of age, sex, glaucomatous optic nerve change and pre-treatment intraocular pressure level on the ocular hypotensive effect of latanoprost in primary open-angle glaucoma cases. Materials and Methods: Primary open-angle glaucoma cases 99 in number who latanoprost treatment had been begun between January 2003 and January 2005, were included to our retrospective study. The cases were divided into groups according to their ages (40-59 year-old and &#8805;60 yearold), pre-treatment intraocular pressure (22-26 mmHg and 27-32 mmHg) and cup/disc ratios (0.2-0.4 and 0.5-1.0). The eyes with higher intraocular pressure; in the case of equality, the right eyes were enrolled. Post treatment amount of decrease in intraocular pressure and percentage of decrease and necessity of change the therapy between the groups were compared statistically by non-parametric t-test, chi-square test and Mann-Whitney U test. Results: Percentage of decrease in intraocular pressure was 28.02%(0-53%) at the post-treatment third month and 32.4%(0-56%) at the post-treatment first year. The change or addition of other anti-glaucoma drops were necessary in 20 cases (20.2%) within the first year of treatment. In respect to ocular hypotensive effect of latanoprost no statistically significant differences were detected between the groups according to their ages, sex and cup/disc ratios (P=0.15, P=0.35 P=0.95.) But pre-treatment intraocular pressures were found to have statistically significant effect on the decrease in intraocular pressure after latanoprost therapy (P<0,001). The necessity of the change or addition of other anti-glaucoma drops were found to be more frequent in male cases and cases with higher cup/disc ratios. Conclusion: It was concluded that ocular hypotensive effect of latanoprost is more in patients with high pre-treatment intraocular pressure; but age, sex and optic nerve changes had no statistically significant effect.

Özet

Amaç: Primer açık açılı glokom olgularında, yaş, cinsiyet, glokomatöz optik sinir hasarı ve tedavi öncesi göz içi basıncı değerleri gibi faktörlerin, latanoprost’un etkinliği üzerine olan etkilerinin araştırılması. Gereç ve Yöntem: Ocak 2003-Ocak 2005 yılları arasında kliniğimizde primer açık açılı glokom teşhisi konan ve latanoprost tedavisi başlanan 99 olgu, ilacın etkinliğini değiştirebilecek faktörler yönünden retrospektif olarak incelendi. Olgular yaşlarına göre 40-59 yaş ve 60 yaş ve üstü, göz içi basıncı değerlerine göre 22-26 mmHg ve 27-32 mmHg arası ve hastalığın evresi yönünden kap/disk oranı 0.2-0.4 ve 0.5-1.0 arası olarak ikişerli gruplara ayrıldı. Olguların göz içi basıncı yüksek olan gözleri veya göz içi basınçlarının eşit olması durumunda sağ gözleri değerlendirmeye alındı. Tedavi sonrası göz içi basıncı değerlerindeki sayısal-yüzdesel düşüşler ve ilaç değişim veya ilaç eklenme gereksinimi yönünden gruplar arasındaki farklılıklar, nonparametrik t-testi, ki-kare testi ve Mann-Whitney U testi ile istatistiksel olarak kıyaslandı. Bulgular: Göz içi basıncında tedavi sonrası 3. ayda ortalama %28.02 (%0-53), 12. ayda ise %32.4 (%5-56) oranında düşüş sağlandı. Tedavi sonrası ilk 1 yıl içerisinde, 20 olguda (%20.2) ilaç değişimi veya ikinci bir ilaç ilavesi gerekti. Latanoprostun göz içi basıncını düşürmedeki etkinliği açısından, olguların yaşı, cinsiyeti ve kap/disk oranının istatistiksel olarak anlamlı ölçüde etkisi saptanmazken (P=0.15, P=0.35 P=0.95), tedavi öncesi göz içi basıncı değerlerinin ise, tedavi sonrası göz içi basıncı değerindeki düşme miktarı ve yüzdesi üzerine, anlamlı ölçüde etkili olduğu görüldü (P= 0.001). Erkek hastalarda ve kap/disk oranı yüksek olanlarda tedavi değişikliği ihtiyacının daha fazla olduğu görüldü. Sonuç: Primer açık açılı glokom olgularında latanoprost etkinliğinin, tedavi öncesi göz içi basıncı yüksek olgularda daha fazla olduğu, ancak yaş, cinsiyet ve glokomatöz optik sinir hasarı seviyesinden etkilenmediği sonucuna gidildi.
