Abstract

Purpose: To evaluate visual acuity and foveal thickness alterations after intravitreal bevacizumab injection in treatment of diabetic macular edema. Materials and Methods: 50 eyes of 43 patients with diabetic maculapathy that underwent single dose intravitreal beva- cizumab (Avastin,) injection were analyzed retrospectively. Best corrected visual acuity (BCVA) was evaluated according Snellen chart . Foveal thickness was measured with optic coherence tomography (OCT) before and 1, 3 and 6 months after injection. Patients were compared in terms of BCVA and foveal thickness at 1st, 3th and 6th months. Results: Mean follow-up period was 9.08±2.26 (6-15) months. Mean BCVA was determined as 0.29±0.19 before injection, 0.42±0.22 at 1st month, 0.37 ± 0.2 at 3th month and 0.33±0.18 at 6th month after injection. The improvement in visual acuity at 1st and 3th months were found statistically significant (p<0.01, p<0.01). The improvement in visual acuity at 6th month was not statistically significant (p=0.094). Mean foveal thickness was measured as 413.8±136 &#956;m before injection, 309.9±103 &#956;m, 330.8±123 &#956;m and 369.3±156 &#956;m at 1st, 3th and 6th months, respectively. The difference between preinjec- tion and postinjection mean foveal thickness changes was founs statistically significant (p<0.01, p<0.01, p<0.02). Conclusion: Effect of single dose intravitreal bevacizumab injection on visual acuity and foveal thickness in therapy of dia- betic retinopathy with macular edema was reached the highest value in first month. The efficacy of injection are sustained for six months, although reduced.

Özet

Amaç: Diabetik retinopatiye bağlı maküla ödemi tedavisinde intravitreal bevacizumab enjeksiyonu sonrası görme keskin- liği ve fovea kalınlığı değişikliklerini incelemek. Gereç ve Yöntem: Diabetik retinopatiye bağlı maküla ödemi tedavisi için intravitreal bevacizumab (Avastin,Genantech) uygulanan 43 hastanın 50 gözü retrospektif olarak incelendi. Hastaların her birine bir defa 1.25 mg/0.05 mI bevacizumab enjeksiyonu yapıldı. Enjeksiyon öncesi ve enjeksiyon sonrası 1. ay, 3. ay ve 6. aylarda en iyi düzeltilmiş görme keskinlikleri (EDGK) ve optik koherens tomografi (OKT) kullanılarak elde edilen fovea kalınlık değerleri kaydedildi. Hastalar 1. ay, 3. ay, 6. aydaki EDGK ve fovea kalınlıkları açısından karşılaştırıldı. Bulgular: Ortalama takip süresi 9.08±2.26 (6-15) aydı. Snellen eşeline göre ortalama EDGK, enjeksiyon öncesi 0.29±0.19, enjeksiyon sonrası 1. ayda 0.42±0.22, 3. ayda 0.37±0.2 ve 6. ayda 0.33±0.18 olarak saptandı. Birinci ve 3. aydaki görme keskinliği değerlerindeki artış istatistiksel olarak anlamlı bulundu (p<0.01, p<0.01). Altıncı aydaki görme keskinliğindeki artış ise istatistiksel olarak anlamlı bulunmadı (p=0.094). Ortalama fovea kalınlığı enjeksiyon öncesi 413.8±136 μm, 1. ayda 309.9±103 μm, 3. ayda 330.8±123 μm, ve 6. ayda 369.3±156 μm olarak ölçüldü. Birinci, 3. ve 6. aydaki ortalama santal maküla kalınlığı değerlerinde, tedavi öncesi ortalama santral maküla kalınlığı değerine göre istatistiksel olarak anlamlı azalma tespit edildi (p<0.01, p<0.01, p=0.02). Tartışma: Diabetik retinopatiye bağlı maküla ödemi tedavisinde tek doz intravitreal bevacizumab enjeksiyonunun fovea kalınlığı ve görme keskinliğine etkisi ilk 1 aylık dönemde en yüksek değere ulaşmaktadır. Enjeksiyonun etkinliği 6ay boyunca azalarak da olsa devam etmektedir.
