ABSTRACT
We evaluated the vulnerability of central nervous system (CNS) in patients with systemic lupus erythematosus (SLE) using exploratory eye movement analysis and random number generation (RNG), and compared the tests in evaluating CNS vulnerability. Nineteen patients received the tests more than a month after SLE onset in nonpsychotic status. Exploratory eye movements were analyzed using an eye-mark recorder that detects corneal reflection of infrared light, and numbers of eye fixations were counted to calculate responsive search score (RSS). Using digits 0 through 9, 100 numbers were vocally generated at a random fashion. "Seriality score" was calculated from the recorded 100 numbers. RSS of SLE patients was similar to that of normal individuals, irrespective of neuropsychiatric lupus history. Seriality score of patients having a history of neuropsychiatric lupus was higher than that of never having it (p < 0.05). No relations were confirmed between RSS and seriality score. The current study suggested heterogeneous nature of SLE in CNS vulnerability when evaluating with seriality score, but not with RSS. There seemed to be a difference between exploratory eye movement analysis and RNG in evaluating CNS vulnerability. Each test seemed to evaluate different aspects of brain function.
