For patients with decompensating congenital fourth nerve palsy, indications for intervention include cosmetically or functionally unacceptable head position, and onset of increasing frequency of diplopia.

Patients with acquired disease from tumors or compressive lesions are usually significantly disturbed by symptoms and are likely to require prism or, in some cases, surgical intervention.
