Abstract

Optic disc drusen (ODD) are benign congenital anomalies of the optic nerve characterized by calcified hyaline bodies. While superficial drusen can be diagnosed easily during fundus examination, detecting buried drusen requires the use of additional imaging methods such as B-scan ultrasonography (USG), fundus fluorescein angiography (FFA), computed tomography (CT) and fundus autofluorescence (FAF). ODD can be detected by USG with the presentation of highly reflective round structures. ODD appear as hyperautofluorescent areas on FAF and bright spots on CT scans. FFA can be helpful in differentiating ODD from true optic disc edema. Optic disc edema shows early hyperfluorescence due to diffuse leakage whereas ODD presents as well-defined hyperfluorescence in the late phase. In recent years, it has been reported that optical coherence tomography (OCT) examination has allowed more detailed evaluation of ODD and yielded useful findings for the differentiation of optic disc edema from ODD. In this review, the role of OCT in the diagnosis of ODD is discussed.

Özet

Optik disk druseni (ODD) kalsifik hyalin birikimi ile karakterize optik sinirin iyi huylu konjenital anamolisidir. Yüzeyel yerleşimli ODD'ler fundus muayenesi esnasında kolayca teşhis edilirken, gömülü olanları tespit edebilmek için B-tarama ultrasonografi (USG), fundus floresein anjiyografi (FFA), bilgisayarlı tomografi (BT), fundus otofloresan (FOF) görüntüleme gibi ek yöntemlere ihtiyaç duyulmaktadır. ODD, USG'de yüksek reflektiviteli yuvarlak yapılar şeklinde tespit edilirler. ODD, FOF'ta, hiper-otofloresan alanlar BT'de beyaz, parlak cisimcikler şeklinde görünürler. FFA, ODD'nin gerçek optik disk ödeminden ayrımında faydalı olabilmektedir. Optik disk ödeminde erken fazda yaygın sızıntıya bağlı hiperfloresans, ODD'de ise geç fazda düzgün sınırlı hiperfloresans görünür. Son yıllarda literatürde optik koherens tomografi (OKT) ile ODD'nin daha detaylı değerlendirildiği ve optik disk ödeminde ayrımında yardımcı bulgular sağladığı bildirilmektedir. Bu derlemede, OKT'nin ODD teşhisindeki yeri literatür eşliğinde irdelenecektir.
