I read with interest the article regarding the clinical significance of retinal spontaneous venous pulsations (SVPs) that was published in the January issue of the Archives (35:37-40, 1978). I presented a paper on this subject at the eighth annual Neurology Resident's and Fellow's Symposium at the University of Miami School of Medicine in June 1975. My work confirms Dr Levin's finding and was published in the Journal of the Florida Medical Association (64:355-357, 1977). It was determined at that time that the incidence of SVPs decreased with increasing age. Other factors besides spinal fluid pressure were obviously involved since the incidence of SVPs was only 40% in this group of 420 consecutively studied, neurologically ill patients. Patients with seizure disorders, cerebrovascular disease, and other CNS problems had a lower-than-expected incidence of SVPs, which is frequently associated with normal CSF pressure. Sixty-five patients underwent lumbar puncture. One patient had
