As a bee scientist and medical doctor, I have recently been contacted by an ophthalmologist in California who noted a couple of cases of visual problems in beekeepers caused by central retinal vein occlusions. I am not aware of this being an ailment of particular concern to beekeepers, but I thought I would inquire among the Bee List subscribers to see whether anyone else is aware of increased prevalence of central retinal vein occlusions in beekeepers. If anyone has any information, please let me know. regards, scott \ ----------------------------- ()())8 Scott Camazine / Penn State University Department of Entomology 501 ASI Building University Park, PA 16802 814-863-1854 [log in to unmask]
