| Popis: | Objective To determine if motion automated perimetry can identify early glaucomatous visual field defects in patients with suspected glaucoma (by disc), those with ocular hypertension, and those with primary open-angle glaucoma. Methods Motion automated perimetry, a foveally centered motion test, and standard visual field tests were conducted on one randomly selected eye of normal patients (n=38), patients with suspected glaucoma (by disc) (n=28), patients with ocular hypertension (n=18), and patients with primary open-angle glaucoma (n=21). Subjects' performance on both motion tests were compared with their performance on standard perimetry. Results Perimetric motion thresholds significantly distinguished the groups ( P ≤.001), while the foveally centered motion test was unable to separate them ( P ≤.32). Of the total patients, 90.5% of those with glaucoma, 39.3% of those with suspected glaucoma, 27.8% of those with ocular hypertension, and 5.3% of the normal subjects had abnormal results on motion automated perimetry testing. Perimetric motion thresholds were significantly correlated with standard visual field thresholds ( P ≤.001). Conclusion Motion automated perimetry identifies visual field defects in patients who already show standard visual field loss as well as in a moderate percentage of those with suspected glaucoma and ocular hypertension, indicating that the testing of discrete locations might be necessary for increased diagnostic utility. |
