Paralysis of the Extraocular Muscles in Tumors of the Sella Turcica Region
Palsies of extraocular muscles in sellar tumors are only rarely observed, in contrast to disturbances of visual acuity and the visual field (Walsh 1956, 1969, Symonds 1962, German 1964). As a rule, they depend on parasellar spreading of the tumor (Cairns 1938, Weinberger et al. 1940, Nicola 1972). Computerized tomography (CT) has proved reliable in the diagnosis of hypophyseal processes (Kazner 1978) especially when there is parasellar spreading. The clinical findings are compared with the CT result in eight patients who had sellar processes with ocular muscle disorders.
