Abstract

Purpose: To compare and evaluate the clinical results of silicone (FP-7) and polypropylene (S-2) Ahmed glaucoma valves (AGV) in neovascular glaucoma cases. Materials and Methods: 26 eyes of 21 patients with neovascular glaucoma were included into study. In 14 eyes polypropylene (model S-2) (group 1) and in 12 eyes silicone (model FP-7) AGV were implanted. All cases were performed under local anesthesia. After fornix-based conjunctival flap was created the valve was positioned 10-12 mm posterior to the limbus in the superotemporal quadrant. Results: The patients were followed up one year. The mean age was 65.42±12.81 years (28-83 years) in group 1 and 57.58±17.21 years (25-77 years) in group 2 (p=0.216). Preoperative mean intraocular pressures (IOP) under medication were 45.46±14.60 mmHg (29-65 mmHg) and 48±8.27 mmHg (37-60 mmHg), respectively group 1 and group 2 (p=0.429). Preoperative visual acuities were between light perception (+) and 1/10 in both groups.Postoperative mean IOP at the end of one year were 18.07±3.81 mmHg and 17.58±4.44 mmHg, respectively group 1 and group 2 (p=0.938). After the operation the number of glaucoma drugs were statistically decreased in both groups (respectively p=0.007 and p=0.01). Hypotony and shallow anterior chamber were observed in 6 eyes (42.8%) in group 1 and 5 eyes (41.6%) in group 2. In group 1 two choroidal detachments and two hyphemas and in group 2 two choroidal detachments and one hyphema were observed. Regarding complications and visual acuities there were no statistically significant difference (p=1.00). In first year surgical success 64.2% in group 1 and 66.6% in group 2 (p=1.00). Conclusion: In neovascular glaucoma cases it was observed that there was no difference regarding IOP reduction and complications between either AGV.

Özet

Amaç: Neovasküler glokom olgularında silikon (FP-7) ile polipropilen (S-2) Ahmed glokom valvinin (AGV), klinik sonuçlarını karşılaştırmak ve değerlendirmek. Gereç ve Yöntem: Neovasküler glokomlu (NVG) 21 hastanın 26 gözü çalışmaya alındı.14 göze polipropilen (S-2) (1. grup), 12 göze de silikon (FP-7) model (2.grup) AGV kullanıldı. Olguların tümüne lokal anestezi altında operasyon yapıldı. Forniks tabanlı konjonktival flep hazırlanıp limbustan 10-12 mm geriye üst temporal kadrana valv yerleştirildi. Bulgular: Hastalar 1 yıl takip edildiler. Birinci grupta yaş ortalaması 65.42±12.81 yaş (28-83 yaş), ikinci grupta yaş ortalaması 57.58±17.21 yaş (25-77 yaş) idi (p=0.216). Ameliyat öncesi birinci grubun GİB ortalaması ilaçlı 45.46±14.60 mmHg (29-65 mmHg), ikinci grubun ise 48±8.27 mmHg (37-60 mmHg) idi.(p=0.429) Her iki grupta da görmeler ameliyat öncesi ışık (+) ile 1/10 aralığında idi. Ameliyat sonrası GİB ortalaması birinci yılda 1. grupta 18.07±3.81 mmHg, 2. grupta 17.58±4.44 mmHg bulundu (p=0.938). Ameliyat sonrası her iki grupta da kullanılan glokom ilaç sayıları istatistiksel olarak azalmıştı. (sırasıyla p=0.007 ve p=0.01) Hipotoni ve ön kamara sığlığı 1. grupta 6 gözde (%42.8), 2. grupta 5 gözde (%41.6) gözlendi. Birinci grupta 2 olguda koroid dekolmanı, 2 olguda hifema ikinci grupta 2 olguda koroid dekolmanı ve bir olguda hifema gözlendi. Komplikasyonlar ve görme keskinlikleri açısından istatistiksel fark yoktu (p=1.00). Birinci yılda cerrahi başarı 1. grupta %64.2, 2. grupta %66.6 bulundu (p=1.00). Sonuç: Neovasküler glokomlu gözlerde, her iki AGV arasında göz içi basıncını düşürme ve komplikasyonlar yönünden farklılığın olmadığı gözlendi.
