Rapid confrontation screening for peripheral visual field defects and extinction
Abstract:Screening for unsuspected visual field defects should form a part of all routine eye examinations. Here, we review a procedure for finger-counting confrontation screening that tests the periphery of all visual field quadrants of each eye, yet requires a total of only four responses from the patient. In addition, the test simultaneously screens for the extinction phenomenon that can accompany unilateral brain damage. Due to its efficiency, we recommend that this procedure form the standard way that screening finger-counting confrontation be performed, with abnormal findings prompting a more detailed assessment of visual fields and further neurological examination as necessary. Our paper is not intended to suggest that finger-counting confrontation is superior to other forms of visual field screening and indeed the literature suggests its sensitivity is limited.
