Ictal body scheme disturbance induced by looking through a small opening.
The case of a patient is reported in which seizures consisting of a feeling that the left arm was absent were induced by looking through a small opening (e.g. camera view finder). The EEG showed right parietal sharp wave discharges between and during such seizures. This observation is interpreted as an example of a reflex epilepsy triggered by the specific stimulus of looking through a small opening, and involving the right parietal lobe.
