EMGs were recorded from the gastrocnemius and anterior tibialis muscles of 77 adult subjects in response to perturbation of stance by upward toe tilts. Subjects aged 22-88 y were initially grouped in seven decades (20s-80s). Each presented a history free of ear disease, eye disease not correctable by lenses, neurological disease, and persistent difficulty with balance or dizziness. All demonstrated functionally normal balance for their age on routine dynamic posturography. EMG recordings yielded onset and offset latencies, durations, and integrated amplitudes of the short and medium latency responses of the gastrocnemius and the long latency responses of the anterior tibialis. Analysis of the data revealed statistically significant left-right differences in amplitude of response and statistically significant height, gender, and age effects. Procedural issues were discussed; data were summarized for normative purposes; and suggestions were made for dealing with statistically significant differences in a clinical environment.

Dizziness stands for vertigo (rotatory and nautic) and dysbalance/unstability. Vertigo originates from the vestibular central nervous system; no eye disease, but nystagmus is often present. Dysbalance/unstability: normal ophthalmological findings exclude ophthalmological pathogenesis. Ophthalmological pathology, especially recently developed may be involved. Uncorrected glasses, eye drops (by systemic absorption), flickering light, and migraine may also cause dysbalance/unstability. Rapid referral to specialist is recommended by fast development of: decreased visual acuity, visual field defects, strabismus, eye movement pathology and nystagmus.

We describe two cases with complaints of atypical headache who were initially diagnosed as having psychiatric problems, but who, after careful evaluation, were found to have an underlying eye disorder. Both patients were known to have an ophthalmic history. Patient A, a 21-year-old female, presented with severe headache, which was so disabling that she was declared unfit for work. A diagnosis of tension headache was made and she received psychological treatment with neurofeedback, homeopathy and acupuncture, which had no effect. Patient B, a 26-year-old male, complained of extreme photophobia, nausea and dizziness. The patient was diagnosed as having a conversion disorder and was admitted to a psychiatric clinic and given psychotropic treatment. Careful ophthalmological examination revealed that an ocular deviation was causing the symptoms in both patients and could be treated appropriately with strabismus surgery. These cases emphasise the importance of a thorough general medical and ophthalmic history and proper examination at all times without putting a psychiatric stigma on the patient.
