[Amblyopia and the visual field]

The author examined 20 hypermetropic eyes with functional amblyopia with application of the objectively sciascopically determined diopters and, separately, without such correction, during the investigation of the visual field using Goldmann kinetic light perimetry in photopia. The starting hypothesis was statistically tested by means of differences of the two arithmetic mean values. Based on the obtained results, the author has found that the values denoting the degree of visual field damage are in correlation with the degree of visual acuity decrease. He also observed that the application of the objectively determined dioptric value leads to the normalization of the visual field in amblyopic persons, although it does not improve visual acuity. This is an important observation, since extensive visual field failings without the introduction of the objectively determined correction may raise suspicion of a retrobulbar inflammation or atrophy of the optic nerve.
