Bilateral optic disc head drusen manifesting as unilateral episodic visual field obscuration: A case report

Optik sinir başı druzeni (OSBD), optik diskte kalsifiye, hyalen benzeri bir materyalin birikmesi sonucu oluşur. Optik disk elevasyonu ve disk sınırlarında silikliğe neden oldukları için genellikle yanlış olarak papilödem teşhisi konulur. Bu yazıda, tek taraflı, epizodik, parsiyel görme alanı bulanıklığı şikayeti ile başvuran ve bilateral OSBD tespit edilen 22 yaşındaki kadın hasta sunulmuştur. Disk druzeninin patogenezi, tanısı ve olası komplikasyonları tartışılmıştır.

Tek taraflı, epidozik görme alanı defekti ile kendini gösteren bilateral optik sinir başı druzeni: Olgu sunumu

Optic nerve head drusen (ONHD) are formed within the substance of the optic disc due to the accumulation of calcified hyaline-like material. They are generally misdiagnosed as papilledema since they elevate the disc and blur the disc margins. In this report, we describe a 22-year-old female patient with unilateral, episodic, partial visual field obscuration diagnosed as bilateral ONHD, the and pathogenesis, diagnosis and possible complications of disc drusen are discussed.
