Fig. 3. Threshold-related screen. This test is an Armaly full-field screening examination, intended for glaucoma testing. The examination emphasizes testing of the central field but includes screening of the peripheral nasal horizontal meridian for nasal steps and temporal periphery for sector defects. This examination is abnormal, demonstrating marked nasal constriction, a dense superior arcuate scotoma, and several abnormal areas in the inferior paracentral region. Full threshold testing is indicated to quantitate the abnormal field. |
