Abstract

Objectives: To investigate the efficacy of single dose intravitreal dexamethasone implant in patients with diabetic macular edema (DME) resistant to anti-VEGF therapy. Materials and Methods: Twenty eyes of 14 patients (8 male, 6 female; mean age, 65±5.7 years) with DME resistant to intravitreal ranibizumab injections were studied. A single intravitreal dexamethasone implant was injected into each eye and patients were followed up for 6 months. Response to therapy was assessed monthly by measuring intraocular pressure (IOP), best-corrected visual acuity (BCVA), and central foveal thickness (CFT). Results: Baseline (before injection) IOP was 14.9±2.7 mmHg and did not change significantly in the six months following injection. Baseline BCVA was 1.04±0.35 LogMAR and improved to 0.86±0.31 at month 1 without statistical significance (p=0.056). CFT was significantly lower in all monthly measurements compared to its baseline value of 682.2±229.2 μm. During the follow-up period, endophthalmitis, significant cataract, or rhegmatogenous retinal detachment were not detected. Conclusion: Intravitreal dexamethasone implant injection is associated with significant CFT reduction for up to six months without causing any complications. Although BCVA did not improve in parallel with the CFT reduction, intravitreal dexamethasone implant should be considered as an effective and safe treatment option in the management of DME patients resistant to anti-VEGF injections.

Özet

Amaç: Anti-VEGF tedaviye dirençli diyabetik maküla ödemi (DMÖ) olgularında tek doz intravitreal deksametazon implantınetkinliğinin araştırılmasıdır.Gereç ve Yöntem: İntravitreal ranibizumab tedavisine dirençli diyabetik maküla ödemi olan 14 hastanın 20 gözü çalışmaya dahiledildi. Her bir göze tek doz intravitreal deksametazon implant enjeksiyonu uygulandı ve hastalar altı ay süreyle izlendi. Tedavi yanıtıaylık göz içi basıncı (GİB), en iyi düzeltilmiş görme keskinliği (EİDGK) ve santral foveal kalınlık (SFK) ölçümleri ile değerlendirildi.Bulgular: Tedavi öncesi GİB 14,9±2,7 mmHg’idi ve enjeksiyon sonrası altı aylık dönemde anlamlı değişim göstermedi. Tedavi öncesiEİDGK 1,04±0,35 LogMAR düzeyindeydi ve birinci ayda istatistiksel olarak anlamlıklık göstermeksizin 0,86±0,31 LogMAR düzeyineyükseldi (p=0,056). SFK, tedavi öncesi 682,2±229,2 μm’luk değere göre tedavi sonrası tüm aylarda istatistiksel olarak anlamlı derecededaha inceydi. İzlem süresince endoftalmi, anlamlı katarakt veya regmatojen retina dekolmanı görülmedi.Sonuç: İntravitreal deksametazon implant, altı aylık dönem içerisinde herhangi bir komplikasyona yol açmaksızın SFK’de anlamlıderecede incelme sağlamaktadır. SFK’deki incelmeye paralel olarak EİDGK artışı sağlanamamış olsa da intravitreal deksametazonimplant anti-VEGF enjeksiyonlarına dirençli DMÖ olgularının tedavisinde etkili ve güvenilir bir tedavi yöntemi olarak göz önündebulundurulmalıdır.
