Abstract

Purpose: To compare the outcomes of grid laser photocoagulation and intravitreal (IV) injections of bevacizumab treatments in patients with macular edema secondary to branch retinal vein occlusion (BRVO). Materials and Methods: Records of 15 patients treated with grid laser photocoagulation (group 1) and 12 patients treated with IV bevacizumab injections (group 2) for macular edema secondary to BRVO reviewed retrospectively. Best corrected visual acuity (BCVA) and central macular thickness (CMT) obtained by Stratus OCT were measured. Results: Mean follow-up time was 9.9±3.1 months in group 1 and 13.2±7.6 months in group 2. BCVA improved significantly from 0.73±0.28 logMAR to 0.55±0.36 logMAR in grid laser photocoagulation group and 0.94±0.43 logMAR to 0.55±0.44 logMAR in IV injection group (respectively p=0.010 and p=0.011). CMT was decreased from 391.6±119.1 μm to 336.4±128.7 μm in group 1 and from 555.7±130.3 μm to 354.2±144.0 μm in group 2. In between group comparisons there were no difference in initial BCVA and BCVA change (respectively p=0.136 and p=0.155). But both initial CMT measurements and CMT improvements were statistically different (respectively p=0.003 and p=0.027). No significant correlation was found between BCVA change and CMT change in both groups. Conclusion: IV bevacizumab injection and grid laser treatment result in significant improvement of visual acuity for patients with macular edema secondary to BRVO.

Özet

Amaç: Retinal ven dal tıkanıklığına (VDT) ikincil maküla ödemi tedavisinde grid lazer fotokoagülasyon ile intravitreal (İV) bevacizumab enjeksiyonu sonuçlarını karşılaştırmak. Gereç ve Yöntem: VDT’ye ikincil maküla ödemi nedeni ile grid lazer fotokoagülasyon ile tedavi edilmiş olan 15 hasta (grup 1) ile bevacizumab enjeksiyonu yapılan 12 hastanın (grup 2) bulguları retrospektif olarak incelendi. İşlemler öncesinde ve sonrasında en iyi düzeltilmiş görme keskinliği (EİDGK) ve optik kohorens tomografi (OKT) ile elde edilen santral maküla kalınlığı (SMK) ölçümleri yapıldı. Bulgular: Ortalama takip süresi grup 1’de 9.9±3.1, grup 2’de 13.2±7.6 aydı. EİDGK grup 1’de 0.73±0.28 logMAR’dan 0.55±0.36 logMAR’a, grup 2’de 0.94±0.43 logMAR’dan 0.55±0.44 logMAR’a yükseldi ve bu yükselme istatistiksel olarak anlamlı bulundu (sırasıyla p=0.010 ve p=0.011). SMK grup 1’de 391.6±119.1 μm’den 336.4±128.7 μm’ye, grup 2’de 555.7±130.3 μm’den 354.2±144.0 μm’ye geriledi. Gruplar arasında başlangıç EİDGK düzeyi ile EİDGK değişimi açısından istatistiksel olarak anlamlı fark saptanmadı (sırasıyla p=0.136 ve p=0.155), ancak başlangıç SMK ve SMK değişimi açısından istatistiksel olarak anlamlı fark saptandı (p=0.003 ve p=0.027). Her iki grupta da EİDGK ve SMK arasında korelasyon saptanmadı. Sonuç: Hem grid lazer fotokoagülasyon hem de İV bevacizumab enjeksiyonu VDT’ye ikincil maküla ödeminde anlamlı iyileşme sağlamaktadır.
