Computer-assisted interpretation of resolution visual fields was performed in 147 normal subjects and 174 consecutive patients with known chiasmal or retrochiasmal lesion. The program identified 99% of normal subjects, and provided support for the correct diagnosis in 64% of patients with chiasmal and 83% of patients with retrochiasmal lesions. In conclusion, computer-assisted interpretation of resolution visual fields can provide considerable support to the final diagnostic decision in patients with lesions of the visual pathways.

In order to find out to which extent high-pass resolution perimetry would detect any changes in patients treated for glaucoma, resolution perimetry results were evaluated from 56 glaucoma patients and 15 untreated ocular hypertensive patients followed for 2 to 3 years. Fifty-nine of the 71 examined patients showed lower resolution thresholds, i.e. increased sensitivity, after 2 years, compared to initial values. The threshold decrease was significantly larger in the treated glaucoma patients (median 1.22 dB) than in the untreated ocular hypertensive patients (0.48 dB). The threshold decrease in the untreated ocular hypertensive group corresponds to the previously described learning effect. In 35 of the 56 treated glaucoma patients the thresholds improved more than 0.84 dB, the upper confidence limit in the untreated group, which may indicate a beneficial effect of antiglaucoma therapy in these patients. The threshold change was unrelated to initial resolution threshold and cannot be explained by a 'sorting' effect. The observations in the current study using resolution perimetry indicate that improved visual function can be demonstrated in many patients treated for early glaucoma, at least during the first 2 years of treatment.

Seventeen subjects with amblyopia due to strabismus and anisometropia were examined using high-pass resolution perimetry. In addition to the standard technique, testing the 5–30° visual field, an optional program testing the central 4° visual field was used. Threshold elevation was confined to the central 4° visual field and strongly correlated with visual acuity, expressed as minimum angle of resolution. Standard high-pass resolution perimetry did not reveal any significant abnormalities in the amblyopic subjects. In conclusion, the technique is useful for the diagnosis of ocular or neurologic disorders also in subjects with a high degree of amblyopia.
