Objective: Aim of this study is evaluation of the predictive effect of biomarkers evaluated by optical coherence tomography(OCT) on vision for at least 6 months in patients who received anti-VEGF therapy for diabetic retinopathy(DR) and who could not receive treatment due to the COVID-19 pandemic.
Material and methods: Age, number of previous injections, pre-injection and last visit best corrected visual acuity(BCVA), HbA1C values, OCT, CMT and OCT biomarkers were evaluated at least 6 months post-injection of patients who received minimum 3 doses of Anti-VEGF due to DR in our clinic between the 7th month of 2019 and the 1st month of 2020. The chi-square test, the paired t test, the regression analysis were used for statistical analysis.
Results: A total of 61 patients, 82 eyes were included in the study, 33 patients(53.2%) were women. Mean age was 64.2(±7.2) years, and BCVA was 0.23±0.19 and 0.25±0.23 at pre-injection and final follow-up, respectively. Initial CMT was 418.6±143.2, and at the last control it was 496.6±134.7 micrometers. The effect of OCT biomarkers on final vision was evaluated; the absence of DRIL, intact EZ-ELM and HRNS below 20 and CMT less than 350 µm after the last injection were found to be statistically significant(p<0.05).
Conclusion: In this process, patients with DR could not receive treatment even though they had an anti-VEGF indication; patients with deterioration in retinal layers, high CMT had worse vision levels. We think that the treatment-free follow-up period of patients who do not have these findings can be extended.

Anti-Vasküler Endotelyal Büyüme Faktörü Uygulanamayan Diyabetik Retinopatili Hastalarda Optik Koherens Tomografi Biyobelirteçlerinin COVID-19 Pandemi Sürecinde Değerlendirilmesi

Öz

Amaç: Diyabetik retinopati (DR) için yükleme ve idame tedavisi alan ve COVİD-19 pandemisi nedeniyle Anti-VEGF uygulanması gerektiği halde tedavisini alamayan hastalar üzerinden optik koherens tomografinin (OKT) ile değerlendirilen biyobelirteçlerinin en az 6 aylık sürede görme üzerine prediktör etkisinin değerlendirilmesi amaçlanmıştır.
Gereç ve yöntemler: Kliniğimizde DR nedeniyle 2019’nin 7.ayı ve 2020’in 1.ayı arası en az 3 doz Anti-VEGF yapılan ancak pandemi nedeniyle sonraki aylarda tekrar tedavi edilemeyen hastaların yaşı, önceki enjeksiyon sayıları, enjeksiyon öncesi, en az 6 ay sonrası en iyi düzeletilmiş görme keskinlikleri (EİDGK), HbA1C değerleri, OKT ile SMK ve OKT biyomarkerları değerlendirildi.
Bulgular: Çalışmaya toplam 61 hastanın, 82 göz dahil edildi, 33 hasta (%53,2) kadındı. Ortalama yaş 64,2 (±7,2), enjeksiyon öncesi ve son kontrolde EİDGK sırasıyla 0,23±0,19 ve 0,25±0,23 idi. İlk SMK 418,6±,143,2, son kontrolde 496,6±134,7 mikrometreydi. SMK’nın 350 µm’den düşük olan hastalarda istatistiksel olarak daha iyi görsel sonuçlar bulundu (p<0,05). OKT biyobelirteçlerinin son görme üzerine etkisi regresyon analizi ile değerlendirildiğinde ise DRIL olmaması, EZ-ELM’nin intakt ve HRNS’nın 20 altında olması istatiksel olarak anlamlı bulundu (p<0,05).
Sonuç: DR’li hastalarda Anti-VEGF endikasyonu olduğu halde tedavi alamadıkları bu süreçte; retina tabakalarında bozulma, yüksek SMK bulunan hastaların görme seviyeleri daha kötü seviyede seyretmiştir. Bu bulguları olmayan hastaların tedavisiz takip süresinin uzatılabileceğini düşünmekteyiz.
