Table 1.
ON Eyes (n = 51) | Non-ON Eyes (n = 65) | ||
---|---|---|---|
Age | 41.0 ± 9.2 | 40.5 ± 9.9 | |
Number of ON Attacks | |||
1 attack (%) | 37 (73%) | NA | |
>1 attack (%) | 14 (27%) | NA | |
Months since last ON attack | 78.9 ± 80.5 | NA | |
Visual Acuity | |||
20/20 or better (%) | 32 (63%) | 60 (92%) | |
20/20 to 20/50 (%) | 19 (37%) | 5 (8%) | |
Years since MS diagnoses | 8.6 ± 6.6 | 5.0 ± 4.4 | |
HVFa mean deviation (dB) | −5.15 ± 6.36 (n = 47) | −2.26 ± 3.63 (n = 57) |
HVF refers to Humphery visual field 30-2 or 24-2 threshold tests. Four ON eyes and 8 non-ON eyes had unreliable HVF (fixation loss, false positives or false negatives > 33%) and were excluded for calculating HVF mean deviation.
