- Abstract: In brain death state, bilateral pupil light reflexes are disappeared, and pupils are fixed with dilated. However, spontaneous movements such as ocular microtremor or bilateral cyclical constriction-dilatation of pupils have been rarely reported in brain death patients. We present a brain death patient whose right pupil displayed spontaneously repetitive constriction and dilatation regardless of external stimuli such as light and pain. Early recognition of this phenomenon may prohibit the delay in the diagnosis of brain death and organ transplantation.
