In clinical trials, most of these events were reversible after topiramate discontinuation
At the optic chiasm, fibres from the nasal half of the retina, corresponding to the temporal visual field, decussate
These defects can occur in the central as well as the peripheral vision
1) •Visual field defects: consider discontinuation of TOPAMAX (5
3) • Metabolic acidosis: baseline and periodic measurement of serum In 2003, the first case of TPM-induced visual field defect was documented by Foroozan and Buono
Further investigation is required before the suspected correlation can be confirmed
Use this order to interpret your Humphrey visual field every time: Confirm it’s the right patient with name and date of birth
Compare to the previous visual fields
A thorough search of available English literature revealed only a small number of reports of
A visual field test measures how well you can see above, below, and on either side of you
normal blind spot is on the retina where the optic nerve is due to NO photoreceptors and is not noticeable
3) •Metabolic acidosis: baseline and periodic measurement of serum bicarbonate is recommended ; consider dose reduction or discontinuation of TOPAMAX Patients exhibit symmetric painless decrease of vision and colour vision, bilateral visual field defects (central or cecocentral scotomas), normal maculae, as well as normal, swollen or pale optic disc
Prophylaxis of migraine Initially 25 mg nightly for 1 wk, then increased at 25 mg daily increments at 1-wk intervals
The visual field is the portion of the subject's surroundings that can be seen at any one time [ 1]
