Other Conditions With Comitant Vertical Deviations
Other conditions and disorders featuring a hypertropia that does not change markedly from right to left gaze include innervational problems, such as superior division (partial) palsy of the third cranial nerve; and mechanical disorders, such as thyroid eye disease, congenital fibrosis of the extraocular muscles, and orbital tumors. These topics are discussed elsewhere in this volume and in other BCSC Sections.
