We tried to better characterize non organic ocular disorders in children and adolescents: particularly clinical, perimetric and electrophysiological features.
We performed a prospective study in 25 cases during a period of 16 months.
Non organic ocular disorders were seen among young girls between 9 and 11 years, mostly with bilateral, symmetrical and rapid visual loss. The symptoms were variable in time and responded favorably to suggestion. The ocular examination was normal. Visual field was abnormal in 52% of cases and very often showed a spiral (or snail) picture or a tubular constriction. 7' pattern visual evoked potentials were present in 88% of cases. The acuity was 20/20 in 92% of cases after the consultation and 100% later.
The ophthalmic and electrophysiologic examination confirmed our diagnosis and eliminated more severe pathology.
