![]() To detect macular damage with perimetry, the 10-2 VF test (or a modified 24-2 VF test) is essential. The eyes missed had widespread macular damage, as well as both shallow and deep local defects.Įyes with macular glaucomatous damage may be classified as normal based on the 24-2 VF alone. ![]() The individual 24-2 metrics missed between 7 (CC) and 20 (MD) eyes. Of the 59, 31 (52.5%) were missed by one or more of the 24-2 metrics. Eyes that were missed on one or more of the 24-2 metrics were classified by damage type based upon circumpapillary RNFL thickness plots.įifty-nine (41.8%) eyes were classified as “abnormal macula,” and comprised the reference standard. The number of abnormal eyes missed (i.e., false negatives) was determined for the following 24-2 VF metrics: MD pattern standard deviation (PSD) glaucoma hemifield test (GHT) cluster criteria (CC) and abnormal points within ± 10°. Eyes were classified as “abnormal macula” if abnormal regions on both the 10-2 VF and OCT plots agreed. Retinal nerve fiber layer (RNFL) and retinal ganglion cell plus inner plexiform (RGC+) probability plots were combined with 10-2 VF probability plots. One hundred forty-one eyes of 141 glaucoma patients or suspects underwent 24-2 VF (mean deviation better than −6 dB), 10-2 VF, and OCT testing. To determine the extent to which the 24-2 visual field (VF) misses macular damage confirmed with both 10-2 VF and optical coherence tomography (OCT) tests and to evaluate the patterns of damage missed. ![]()
