| Popis: | The functional effect of the pineal gland cyst is difficult to evaluate with visual field examination. The aim of this study is to investigate the usefulness of visual evoked potentials (VEP) in patients with pineal gland cyst due to the possible compression on the visual pathway. Subjects and methods Black-and-white pattern-reversal checkerboard VEP were recorded in 75 patients (50 females and 25 males, mean age 26.3 ± 15.7 and 25.6 ± 17.6 years, respectively) with pineal gland cyst detected on magnetic resonance of the brain (subject group) and 75 age and sex-matched control subjects (control group). Amplitudes and P100 latencies were collected and later grouped as: (1) normal finding ; (2) prechiasmal ; (3) prechiasmal and postchiasmal ; and (4) postchiasmal dysfunction. Results P100 latencies differed significantly between subject (110.26 ± 13.23 ms) and control group (101.01 ± 5.36 ms) (p |
