N2 - Purpose: To examine the usefulness of OCT for studying eyes with advanced glaucoma (i.e., eyes with a 24-2 visual field [VF] mean deviation [MD] worse than –15 dB], we tested the hypothesis that if these eyes had a 10-2 total deviation (TD) map with points better than –8 dB, then the topographically corresponding regions on the circumpapillary retinal nerve fiber layer (cpRNFL) should show a preserved region. Design: Evaluation of technology study. Participants: Thirty-nine eyes from 33 patients (mean age, 68.8±9.2 years) with a diagnosis of glaucoma showed a 24-2 VF with an MD of –15 dB or less (mean, –18.94±2.95 dB). All eyes additionally had a 10-2 VF and an averaged OCT circle scan. Methods: Each scan was inspected, and preserved cpRNFL regions of the disc associated with the macula (central ±8°) were delineated. Main Outcome Measures: The number of eyes with preserved cpRNFL regions and their association with preserved VF locations (i.e., better than –8 dB) shown in the 10-2 VF TD map. Results: Thirty-eight of the 39 eyes showed 1 or more points on the 10-2 VF with TD values that were better than –8 dB (mean, 25.7±12.6 points). For all 39 eyes, there was a preserved portion of the cpRNFL on the circle scan within the disc region associated with the macula. However for 3 of these eyes, this region was hypodense and could be a challenge for the clinician to identify. Conclusions: OCT scans can be used to assess and potentially follow up the preserved regions of cpRNFL associated with the macula in eyes with advanced glaucoma if there is a preserved region on the 10-2 VF better than –8 dB.
