Abstract

The recently developed wide-field imaging systems (WIS) enable 200 degrees imaging of retina by just one shot and angiographic and autofluorescence imaging of retinal periphery. In addition to facilitating the detection of retinal pathologies, WIS revealed the importance of lesions in retinal periphery and peripheral non-perfusion areas invisible by standard angiography. The novel finding of utmost importance for diabetic retinopathy (DR) patients was the 3 fold increased risk of progression assessed for peripheral DR lesions compared to that in posterior pole. Detection of peripheral non-perfusion areas in DR or retinal vein occlusion cases with refractory macular edema altered the management approach. On the other hand by means of WIS new terms have been brought into the era like “peripheral vascular leakage” whose relevance and importance is unknown for retinal vascular diseases. In age related macular degeneration, a disease known to affect the macula, WIS proved the effect on peripheral retina documented by both angiography and also peripheral autofluorescence. WIS further contributes for the detection of additional pathologies in diseases known to affect the peripheral retina like uveitis, degenerative myopia etc.WIS that enabled documentation of retinal periphery and thus seems to change the treatment modality and probably clinical classification of unknown or treatment refractory pathologies in retinal diseases where we mainly focused to macula always

Özet

Yakın zamanda kullanıma giren geniş açı görüntüleme (GAG) sistemleri sayesinde, retina 200 derecelik kısmının tek bir çekimle görüntülenmesi, retina periferinin anjiyografik ve otoflöresan görüntülerinin alınması mümkün hale gelmiştir. GAG retina hastalıklarının saptanmasını kolaylaştırmanın yanı sıra retina periferindeki lezyonların ve standart anjiyografi ile saptanamayan periferik perfüze olmayan alanların önemini ortaya çıkarmıştır. Diyabetik retinopati (DR) olguları açısından en önemli yeni bulgu, periferik DR lezyonlarının ilerleme riskinin arka kutuptakilere göre 3 kat daha yüksek olduğunun saptanması olmuştur. Tedaviye dirençli maküla ödemi olan DR ve retinal ven tıkanıklığı olgularında periferde perfüze olmayan alanların görülmesi ise dirençli olgulara tedavi yaklaşımını değiştirmiştir. Bunun yanı sıra GAG sistemleri "periferik vasküler sızıntı" gibi retina vasküler hastalıkları için yeni, henüz önemini ve anlamını çok da iyi bilemediğimiz kavramları gündeme getirmiştir. Makülanın bir hastalığı olarak bildiğimiz yaşa bağlı maküla dejenerasyonunda ise GAG sayesinde perifer retinanın da etkilendiği gerek anjiyografi gerekse periferik otoflöresan görüntülerle kanıtlanmıştır. Retina periferini etkilediği bilinen üveit, dejeneratif miyopi vb hastalıklarda ise birçok ek patolojinin saptanmasına katkıda bulunmaktadır. Perifer retinanın dokümantasyonunu sağlayan GAG sistemleri hep makülaya odaklandığımız retina hastalıklarında bilinmeyen ya da tedavi direnç gösteren patolojilerin tedavi modalitesini ve belki de bazı hastalıkların klinik sınıflamasını değiştirecek gibi görünmektedir
