However, drug effectiveness is short and ellipsoid zone loss seems to be the main problem that limits the success of treatment in this diffi cult-to-treat patient population.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Purpose: To assess the short-term safety and effi cacy of intravitreal dexamethasone implant (DEX implant) in patients with persistent diabetic macular edema.Materials and Methods: A retrospective study was conducted 24 eyes of 19 patients with persistent diabetic macular edema (>=250 ?m) though macular laser and antivegf agents.
📊
Key Findings & Data:Best corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure(IOP), adverse events and morphological changes on OCT were examined at baseline, month 1, 3 and 4.Results: Preoperative mean BCVA was 0.80±0.40 (logMAR) and signifi cantly improved 1 (0.59±0.30) and 3 months (0.64±0.35) after injection (p<0.001).

Abstract

Purpose: To assess the short-term safety and effi cacy of intravitreal dexamethasone implant (DEX implant) in patients with persistent diabetic macular edema.Materials and Methods: A retrospective study was conducted 24 eyes of 19 patients with persistent diabetic macular edema (>=250 ?m) though macular laser and antivegf agents. Best corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure(IOP), adverse events and morphological changes on OCT were examined at baseline, month 1, 3 and 4.Results: Preoperative mean BCVA was 0.80±0.40 (logMAR) and signifi cantly improved 1 (0.59±0.30) and 3 months (0.64±0.35) after injection (p<0.001). Preoperative mean CMT was 586±203?m and decreased to 230±77 and 274±115 1 and 3 months after injection (p<0.001), respectively. Mean BCVA and CMT values were also similarly improved for the 4 month follow-up. Reinjection required after 3 months in 63% and after 4 months in 88% of patients. No serious adverse events were observed. 21 % of patients only had a preserved ellipsoid zone.Conclusion: DEX implant seems to be an effective and safe treatment in patients with persistent diabetic macular edema. However, drug effectiveness is short and ellipsoid zone loss seems to be the main problem that limits the success of treatment in this diffi cult-to-treat patient population.

Özet

Amaç: Persistan diabetik makula ödemi olan hastalarda intravitreal Deksametazon implantın (DEX implant) kısa dönem etkinlik ve güvenirliğinin değerlendirilmesiGereç ve Yöntemler: Retrospektif bu çalışmada uygulanan maküler lazer ve anti-VEGF ajanlara rağmen makula ödemi devam eden(>=250 ?m) 19 hastanın 24 gözü değerlendirildi. En iyi düzeltilmiş görme keskinliği (EİDGK), santral makula kalınlığı(SMK), göz içi basıncı(GİB), yan etkiler, OCT'deki morfolojik değişiklikler başlangıçta, 1, 3, 4.aylarda değerlendirildi. Bulgular: Enjeksiyon öncesi ortalama EİDGK 0.80±0.40 (logMAR)'dan 1. ve 3. aylarda sırasıyla 0.59±0.30 ve 0.64±0.35 logMAR'a yükseldi (p<0.001). Enjeksiyon öncesi ortalama SMK 586±203 ?m iken 1. ayda 230±77 ?m 3. ayda ise 274±115 ?m'a düşmüştür (p<0.001). Ortalama EİDGK ve SMK 4. ay takip hastalarında da benzer şekilde düzelme gösterdi. %63 hastada 3.ay sonunda reenjeksiyon gerekirken, %88 hastada ise 4.ay sonunda enjeksiyon gerekmiştir. Hiçbir hastada ciddi bir yan etki izlenmemiştir. Sadece %21 hastada ellipsoid zonun sağlam olduğu gözlenmiştir. Sonuç: DEX implant persistan diabetik makula ödemi olan hastalarda etkili ve güvenli bir tedavi olarak gözükmektedir. Ancak bu zor tedavi edilen hasta grubunda ilacın etkinliği kısadır ve ellipsoid zon hasarı tedavinin etkinliğini kısıtlayan en önemli etmendir.
