The optic nerve disk in myopic children with elevated intraocular pressure

: The optic nerve disc of short-sighted children with elevated intraocular pressure was investigated to achieve early assessment of glaucoma and to detect signs which differentiate changes in the disc caused by short-sightedness from changes caused by glaucoma. The authors examined 16 eyes of 8 short-sighted children with elevated intraocular pressure. In addition to the basic ophthalmological examination they made a digital analysis of the optic nerve disc incl. planimetric evaluation of the dimensions of the disc, excavation and the neuroretinal rim. In two patients despite the higher intraocular pressure the area of the rim was supraliminal. In three patients the narrower area of the neuroretinal rim increased the probability of glaucoma In two patients with anisometropia on the eye with greater myopia the intraocular pressure was higher and the neuroretinal rim narrower as compared with the other eye. In one patient the area of the rim was very narrow and the diagnosis of glaucoma was confirmed also by arcuate scotoma in the lower part of the visual field corresponding to the narrow rim on top.
