Purpose: The aim of this study was to assess behavioral aspects of visual function and visuoperceptual abilities in patients with Panayiotopoulos syndrome (PS), and their possible associations with clinical and electroencephalography (EEG) findings in order to establish the possible effect of interictal paroxysmalactivityonvisual performance. Methods: The cohort included 28 patients (14 male and 14 female) of ages rangingbetween4 and 15 years.All patients underwent serial videopolygraphic studies and a detailed battery of tests assessing visual abilities, including assessment of acuity, stereopsis, visual fields, and visuoperceptual abilities; tests included the Movement Assessment Battery for Children, the Visuo Motor Integration tests, and evaluation of motion and form coherence threshold. Results: On the assessment of visual function, only 4 of the 28 (15%) had abnormal crowding acuity and one had abnormal stereopsis. On the visuoperceptual assessment, one patient had abnormal results on the Visuo Motor Integration tests, and one on the Movement Assessment Battery for Children, whereas 4 (15%) had abnormal results for form coherence threshold and one for motion threshold. Discussion: Our results suggest that, although most of our patients had focal or diffuse EEG abnormalities involving the occipital regions, abnormalities of visual and visuoperceptual function were relatively uncommon.
