ABSTRACT

Dysthyroid optic neuropathy is an important secondary pathological condition of thyroid-associated ophthalmopathy, characterized clinically by several clinical manifestations, including reduced visual acuity, impairment of color vision, relative afferent pupillary defect, and optic disk edema or atrophy. Ophthalmological auxiliary examination shows abnormal vision field and visual evoked potential, etc., and imagining examination shows orbital apex crowding, which can assist diagnosis. The pathogenesis of this disease is still unclear. With previous studies proposing that it was related to optic nerve compression, stretch, and ischemia. Treatment methods include high-dose intravenous glucocorticoid, orbital decompression, orbital radiation therapy, and biological agent. This article systematically reviews the research progress on the epidemiological characteristics, pathogenesis, diagnosis, and treatment of this disease, with a view to providing useful reference for future in-depth clinical practice and scientific research.
