Abstract Purpose to test the ability of frequency-doubling technology (FDT) perimetry to detect dysthyroid optic neuropathy (DON). Methods Fifteen eyes of 15 patients with DON and 15 healthy control eyes were studied. Eligible eyes had a diagnosis of DON based on visual field abnormalities on standard automated perimetry and had visual acuity better than 20/30. FDT testing was performed using both the C-20-5 screening test and the C-20 full-threshold test. Normal and DON eyes were compared with regard to FDT mean sensitivity. Results Sensitivity ranges were 40.0%–86.7% for the screening test, and 53.3%–100.0% (total deviation) and 20.0–93.3 (pattern deviation) for the C-20 threshold test. The corresponding specificity ranges were 86.7–100.0, 33.3–93.3, and 26.7–100.0, respectively. The best sensitivity/specificity ratios were for one abnormal point depressed Conclusions FDT perimetry is a useful screening tool for DON in eyes with normal or only slightly reduced visual acuity.
