Topiramate, an antiepileptic drug is reported to cause various ocular adverse effects like acute onset myopia, glaucoma. Visual field defect is an uncommon, serious treatment emergent adverse effect. We are reporting two cases of suspected topiramate induced visual field defects.Both the cases were on topiramate for more than 6 months as add-on therapy at daily doses ranging from 100-150mg. The...

tion. She described distortion without scotoma on the Amsler grid bilaterally (Figure 1C). Examination findings were otherwise normal except for stage 2 papilledema in both eyes (Figure 2D) and moderate enlargement of the physiologic blind spots on automated perimetry in both eyes. The MRI results were normal. Lumbar puncture showed an opening pressure of 410 mm CSF, with normal indices. Result...

Is anything new in functional testing? There have been many attempts to refine psychophysical and electrophysiological techniques over the last 20 years to enable earlier detection and/or possibly provide an objective means for monitoring function. While a few techniques survive in clinical practice, there has generally not been any major breakthroughs in recent times in the functional testing ...

The difference in threshold sensitivities that are found when examining the visual field (VF) with static versus kinetic perimetric methods is called stato-kinetic dissociation (SKD). In this pilot study, we describe a semi-automated procedure for quantifying SKD. Fifteen patients with VF defects were examined with kinetic and static perimetry. SKD values were defined as positive when the stati...

PURPOSE To compare the visual fields (VFs) of preperimetric open angle glaucoma (OAG) patients (preperimetric glaucoma VFs, PPGVFs) with the VFs of healthy eyes, and to discriminate these two groups by using the Random Forests machine-learning method. METHODS All VFs before a first diagnosis of manifest glaucoma (Anderson-Patella's criteria) were classified as PPGVFs. Series of VFs were obtai...
