Isolated inferior oblique paresis from brain-stem infarction. Perspective on oculomotor fascicular organization in the ventral midbrain tegmentum.
We present the case of an isolated inferior oblique muscle paresis from ventral midbrain infarction involving the oculomotor fascicular fibers. Based on this case and a review of the literature, the anatomic organization of the oculomotor nerve fascicles and of the pupillary fibers in the ventral midbrain tegmentum is proposed.
