Influence of Amblyopia on High-Pass Resolution Perimetry

Abstract

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.

A morpho-functional study of amblyopic eyes with the use of optical coherence tomography and microperimetry

“…6 Stability of fixation has been shown to be abnormal in amblyopia. 8,22 In addition, in many studies 2,6,8,23,24 authors have identified central depressions in amblyopic patients, especially in those presenting with severe amblyopia and deprivation amblyopia. Johnson 8 reported that amblyopia is associated with a generalized depression of light sensitivity (greatest at the fovea and correlated with visual acuity loss) and small focal deficits.…”
