Purpose:

: To evaluate the diagnostic power of Visual Evoked Potential (VEP) and Standard Achromatic Perimetry (SAP) in a group of patients with Multiple Sclerosis (MS) and a history of optic neuritis (ON).

Methods:

: 136 eyes of 68 patients (11 male and 57 female, average age 27.18 years) with a confirmed diagnosis of MS underwent SAP and pattern VEPs. 67 eyes (49.2%) had no history of ocular involvement and a negative ophthalmologic examination, while 69 had proven ON according to physical examination. The mean deviation (MD) and the pattern standard deviation (PSD) of perimetry and the amplitude & latency of VEP in both normal and abnormal eyes were recorded. MD & PSD <0.5% and pl00 latency more than 118 millisecond were considered abnormal.

Results:

: MD was abnormal in 93.9% of the eyes with ON, PSD was abnormal in 69.4% and latency was abnormal in 55% of the affected eyes with ON. In overall, VEP can diagnose 55% of the eyes affected with ON and SAP can diagnose 96%. In statistical analysis of MD, PSD, latency and amplitude values with Mann-Whitney Test MD and PSD were statistically significant (MD has p<0.001, PSD has P<0.05, latency has p=0.83 and amplitude has p=0.38).

Conclusion:

The results of this study demonstrate that SAP is more sensitive than VEP in the diagnosis of ON .SAP is a less operator and patient dependent technique and the patient test reliability can be assessed with parameters such as False-positive response rate, False-negative response rate, Fixation loss & Short-term fluctuation measurement. Because of these advantages, SAP has better sensitivity than VEP in the diagnosis of ON. Our results suggest that clinical and subclinical visual involvement of ON can be better diagnosed using both SAP and VEP tests, together.
