Abstract

In the past three decades, there have been countless advances in imaging modalities that have revolutionized evaluation, management, and treatment of neuro-ophthalmic disorders. Non-invasive approaches for early detection and monitoring of treatments have decreased morbidity and mortality. Understanding of basic methods of imaging techniques and choice of imaging modalities in cases encountered in neuro-ophthalmology clinic is critical for proper evaluation of patients. Two main imaging modalities that are often used are computed tomography (CT) and magnetic resonance imaging (MRI). However, variations of these modalities and appropriate location of imaging must be considered in each clinical scenario. In this article, we review and summarize the best neuroimaging studies for specific neuro-ophthalmic indications and the diagnostic radiographic findings for important clinical entities.

Keywords: Computed tomography; Imaging; Magnetic resonance imaging; Neuroophthalmology.

A 20 year old male with allergic fungal sinusitis with severe expansion of the ethmoid sinus pressing on the medial rectus and pushing the orbital content anteriorly. The CT scan (A) shows great details of the bony structure, while the T1sequence MRI with fat suppression (B) shows the great details of the soft tissue in orbit and sinus.
