Amaç: Çalışmanın amacı neovasküler glokom tedavisinde (NVG) intravitreal bevacizumab (İVB), panretinal fotokoagülasyon (PRFK) ve diyot lazer siklodestrüksiyon (DLSD) kombine tedavisinin etkinlik ve güvenilirliğini araştırmaktı. Gereç ve Yöntemler: Bu amaçla Nisan 2015- Temmuz 2016 döneminde NVG nedeni ile tedavi gören hastaların bilgileri geriye dönük olarak incelendi. Tedavi protokolü İVB'yi takiben PRFK ve sonrasında da DLSD uygulamasından oluşmakta idi. Hastaların tedavi öncesi ve sonrası görme keskinlikleri (GK) ve göz içi basıncı (GİB) düzeyleri karşılaştırıldı. Demografik özellikleri ve tedavi komplikasyonları da kaydedildi. Başarı ölçüsü olarak başlangıç görmenin korunması ve DLSD tekrarı dışında filtran cerrahi ve seton implantasyonu gibi ek cerrahi işlemlere gerek kalmadan GİB'in kontrol altına alınması (≤21 mmHg) olarak belirlendi. Bulgular: Çalışmaya 15'i erkek, 12'si kadın toplam 27 hastanın 27 gözü dâhil edildi. Hastaların ortalama yaşı 62±12 yıl; ortalama takip süresi 6,7±0,7 ay idi. Tedavi öncesi ortalama GK 2,62±0,76 logMAR iken, tedavi sonrasında 2,44±0,87 logMAR olarak bulundu. GİB değeri tedavi öncesi 44,1±11 mmHg iken, tedavi sonrasında ortalama 18,1±3,4 mmHg değerine düştü. Altı hastaya GİB'in yüksek seyretmesi nedeni ile ikinci kez DLSD uygulanması gerekti. Bir (%3,7) hastada ikinci DLSD uygulamasından sonra kronik hipotoni gelişti. Bunun dışında ygulanan işlemlere bağlı herhangi bir komplikasyon görülmedi. Hiçbir hastada ek olarak filtran cerrahi ya da seton implantasyonuna gerek duyulmadı. Bir (%3,7) hastada tedaviye bağlı hipotoni gelişti. Sonuç: NVG'de İVB, PRFK ve DLSD kombine tedavisi GİB'in kontrol altına alınmasında etkili ve komplikasyon oranı düşük bir yöntemdir.

Objective: The purpose of this study was to analyse effectiveness and safety of combined therapy of intravitreal bevacizumab (IVB), panretinal photocoagulation (PRP) and diode laser cyclodestruction (DLCD) in neovascular glaucoma (NVG). Materials and Methods: For this purpose, medical records of the patients with NVG who underwent treatment between April 2015 and July 2016 were reviewed. Treatment protocol contained PRP following IVB and subsequent DLCD procedures. Visual acuities (VA) and intraocular pressure (IOP) measurements were compared between baseline and post-treatment. Demographic features and complications were also recorded. The criteria of success defined as a preservation of initial visual acuity and maintaining normal intraocular pressure (≤21 mmHg) without needing any other surgery except repetition of DLCD. Results: Twenty seven patients included in the study had a mean age of 62±12 years. Mean follow-up was 6.7±0.7 months. Baseline VA was 2.62±0.76 logMAR and changed to 2.44±0.87 logMAR. Baseline IOP was 44.1±11 mmHg and decreased to 18.1±3.4 mmHg. Six patients underwent DLCD for the second time due to the high IOP. One patient (3.7%) developed chronic hypotonia after the second DLCD. No other complication related to the treatment procedures was observed. Conclusion: Combined therapy of IVB, PRP and DLCP was effective procedure on IOP control. The procedure also has low complication rates in NVG treatment.
