  • Title: Rare Cause of Blurred Vision: Unilateral Primary Dural Ectasia of the Optic Nerve Sheath.
    Author: Gozgec E, Ogul H.
    Journal: J Craniofac Surg; 2021 Jun 01; 32(4):e380-e381. PubMed ID: 33273201.
    Abstract:
    Dural ectasia, also known as meningocele of the optic nerve sheath, is a rare benign pathology. Magnetic resonance imaging has a great role in the diagnosis of this condition, which has nonspecific symptoms such as progressive blurred vision. It is observed as cerebrospinal fluid accumulation within the expanded nerve sheath around the optic nerve. Treatment is planned after differential diagnosis of other pathologies such as mass and inflammation in addition to diagnosis with magnetic resonance imaging. Medical treatment is usually sufficient, and surgical treatment is planned for progressive patients.
