ROGANO, Luiz A.; ASSIS, Marushcka and TEIXEIRA, Manoel J.. Horner syndrome after stereotactic Parkinson's surgery. Arq. Neuro-Psiquiatr. [online]. 2003, vol.61, n.2A, pp.248-249. ISSN 0004-282X. http://dx.doi.org/10.1590/S0004-282X2003000200015.
We present ten patients with Parkinson's disease who underwent stereotactic ablative radiofrequency procedures. Seven patients underwent pallidotomy, two subthalamotomy and VIM, and one subthalamotomy. Seven developed miosis and all semiptosis ipsilateral immediately after the procedure. The occurrence of Horner's syndrome is probably due to the lesion of sympathetic fibers among hypothalamus, Forel's field and thalamus after the stereotactic procedure.
