Results
In 16 patients (55%) with oculomotor muscles tumors decreased contractility were revealed due to the muscle structure invasion by tumor,
there were no limitations of optic nerve movement despite adjacent position of the nerve to the tumor (Fig.
1,
Fig.
2).
Limitations of optic nerve movement were revealed in 8 patients (28%) with nerve tumors,
the globe movement and muscles contractility were unimpaired (Fig.
3,
Fig.
4).
In patients with small tumors of globe coats (n=4; 14%) there were no signs of movement limitations.
In one case (3%) the sphenoid wing meningioma with expansion to the orbit was found.
Decreased contractility of superior rectus oculomotor muscle was revealed due to the expansion growth of meningioma.
