Summary
The adrenergic innervation of the eye of rabbits, rats, guinea-pigs, cats, and goats were studied with chemical estimates of noradrenaline and fluorescence microscopical demonstration of adrenergic fibres after sympathetic denervations. Unilateral removal of the cervical sympathetic chain usually resulted in a complete denervation of the eye. There was no significant re-innervation up to 18 weeks after the sympathectomy. In a few instances adrenergic fibres remained after unilateral sympathectomy; this at times occurred also after bilateral cervical sympathectomy. The fibres that remained in the latter event were usually confined to one side. The result suggests that fibres arising from aberrant ganglia situated cranially to the cervical sympathetic chain are confined to the homolateral side.
