Abstract

The visual acuity of the patient with ethambutol optic neuropathy will recover within 3 to 4 months after discontinuing the drug. We studied the extent of the recovery of other visual functions. Thirty-six axial type ethambutol optic neuropathy patients, who visited our neuro-ophthalmology clinic from January, 1990, to December, 1993, were included in this study. Fifteen patients (29 eyes) regained their visual acuity to better than 1.0. The average follow-up period following the recovery is 21.7 months. Pattern reversal VEP, Farnsworth-Munsell 100-Hue color vision test, critical flicker frequency (CFF), visual field perimetry, contrast sensitivity and edge-light pupil cycle time were assessed for every affected eye. Latency (P100) of visually evoked potential was delayed in 34.5% (10/29) of eyes. In color vision, 48.3% (14/29) of eyes had deutan or tritan defect. An abnormality of red CFF with value lower than 31 Hz was revealed 51.7% (15/29) eyes. In the visual field, 58.6% (17/29) of eyes had paracentral scotoma, arcuate scotoma, or enlargement of physiologic blind spot. Contrast sensitivity was depressed in 62.1% (18/29) of eyes, mainly at middle and low spatial frequency. Pupil cycle time was prolonged in 72.4% (21/29) of ...Continue Reading
