This paper reviews the most common types of artifacts on the optical coherence tomography report that may be confused with glaucomatous damage.

In such cases, the probability maps (also known as deviation maps) show abnormal (red and yellow) regions, which may mislead the clinician to assume […]

Objectives: To determine the frequency and characteristics of alterations in ophthalmologic examinations of optic nerve and macula coherence tomography (OCT), and Campimetry in multiple sclerosis (MS) patients. Methods: Sixty eyes were examined, 30 of which were diagnosed with MS and 30 of the control patients, all attended at the General Hospital of the Federal District of Brazil. The patients were evaluated regarding the parameters: characteristics and alterations of the ophthalmological examination, OCT of the nerve and macula and Campimetry. Results: […]
