What is photosensitive epilepsy?

Epilepsy with seizures triggered by flickering or flashing lights. It also may be called photic epilepsy or photogenic epilepsy. Photosensitive epilepsy is a fairly rare form of epilepsy that can trigger a seizure on exposure to certain types of flashing or flickering lights or patterns. Only a small percent of epilepsy sufferers are photosensitive, although the condition may also manifest itself in people with no previous history of epilepsy. It is more common in younger people.


Suppressive efficacy by a commercially available blue lens on PPR in 610 photosensitive epilepsy patients.

Six hundred ten epilepsy patients were tested. Four hundred (66%) were female patients; 396 (65%) were younger than 14 years. Three hundred eighty-one (62%) subjects were pharmacologically treated at the time of investigation. Z1 lenses made PPR disappear in 463 (75.9%) patients, and PPR was considerably reduced in an additional 109 (17.9%) of them. photoparoxysmal response remained unchanged only in the remaining 38 (6.2%) patients. The response of PPR to Z1 lenses was not significantly influenced by the patients' age, sex, or type of epilepsy. No difference was found between pharmacologically treated and untreated patients.

  Treatment of photosensitivity.

Apart from individual preventive measures (use of specific television or video screens, colored glasses, etc.), prevention and warning on a larger scale are helpful.


A novel nonpharmacologic treatment for photosensitive epilepsy: a report of three patients tested with blue cross-polarized glasses.

These preliminary data suggest that blue cross-polarized lenses may be useful in the treatment of photosensitive epilepsies and that their efficacy can be predicted in the EEG laboratory.


Treatment of photosensitive epilepsy using coloured glasses.

There was a modest reduction in EEG photosensitivity with the coloured lenses but also to an equivalent or lesser extent with grey in all of the eight patients examined in this way.


Effectiveness of a particular blue lens on photoparoxysmal response in photosensitive epileptic patients.

We found that the experimental lens type was very effective for photosensitivity inhibition in epileptic subjects. Indeed, photoparoxysmal response (PPR) disappeared in 64 of 83 patients (77%) and diminished in 16 (19%).


Usefulness of blue sunglasses in photosensitive epilepsy.

These results suggest that the suppressive effect of the three sunglasses on FDP stimulation is mainly due to a luminance diminution, whereas that of blue sunglasses on RF stimulation is produced by an inhibitory effect of short wavelengths and possibly by a luminance diminution. Thus, blue sunglasses are thought to be useful in the treatment of patients with photosensitive epilepsy.

  Colour and photosensitive epilepsy.

We suggest that the blue filter allows a small percentage of light transmission and under these conditions the electrical events that follow light stimulation do not occur.
