Analysis of Visual Field Defect in Patient with Brain Lesion

ABSTRACT

PURPOSE: In this study we analyzed the results of visual field tests in patients diagnosed with a brain lesion in an ophthalmology clinic. METHODS: The medical records of 55 patients who underwent visual field examinations and diagnosed with brain pathology using magnetic resonance imaging (MRI) from January 1, 2005 to June 30, 2014 were retrospectively investigated. RESULTS: Of the 55 patients (MF = 3025), 31 displayed symmetrical hemianopsia, a typical visual field defect associated with brain lesions. Twenty-four patients showed atypical visual field defect (20 showed normal visual field despite the brain lesion, 3 had bilateral narrowing of the peripheral visual field in 2 cerebral infarctions and 1 multiple sclerosis, and 1 had horizontal inferior visual field defect in 1 eye from nasopharyngeal cancer). CONCLUSIONS: Patients having a brain lesion with the optic tract invasion may present with atypical visual field defects. The peripheral visual field constriction and horizontal inferior visual field defect in 1 eye could be the visual field defect in patients with a brain lesion.
