Abstract

Purpose: To analyse the prognostic factors and the association of baseline prism diopter with third, fourth and sixth cranial nerve palsies

Methods: 43 cases of cranial nerve palsies were included in the study. The ocular deviation was measured with a baseline prism bar cover test (PBCT) and grouped according to etiology and the cranial nerve. Group comparison was done based on the baseline PD and the recovery duration. Recovery was defined as less than 8 PD of deviation or absent subjective diplopia of the patient.

Results: The recovery duration had a significant association between the type of cranial nerve involvement (p-Value = 0.021). There was also a significant association between the baseline prism diopter and the type of cranial nerve involvement (p-Value = 0.002).

Conclusion: Recovery duration depends on the type of cranial nerve involvement. There is a significant association between the baseline prism diopter and the type of cranial nerve involvement.
