The Reversibility of Visual Field Defects in the Juvenile Glaucoma Cases

Abstract

In the early stage of juvenile glaucoma cases, we followed up the changes of the spot-like scotomas in the Bjerrum area with newly developed our Quantitative Maculometry with direct fundus examination and the other perimetries. In the present study, we analysed the relationship between the appearance of scotomas and the defects of the arcuate nerve fiber bundles which were photographed through red-free filters, in other words, we marked the scotomas on the fundus photographs and determined their accurate position in the fundus. In some cases with no nerve fiber bundle defects, the scotomas diminished or disappeared after the intraocular pressure was controlled. However, if the nerve fiber bundle defects had already appeared, the scotomas did not diminish under the control of the ocular pressure. In the cases of the juvenile glaucoma, the scotomas without nerve fiber bundle defects were considered that they have the possibility of a transient loss of the nerve fiber function.
