SP 740 OP 747 DO 10.1136/bjo.60.11.740 VO 60 IS 11 A1 D R Lucas A1 A C Dunham A1 W R Lee A1 W Weir A1 F C Wilkinson YR 1976 UL http://bjo.bmj.com/content/60/11/740.abstract AB Tissue removed from nine new cases from 18 hours to 20 weeks after injury by a golf ball contained crystalline and other foreign material to which there was a mild inflammatory reaction followed by macrophagic activity and fibrosis. Optical and electron probe analysis showed that the crystalline material was crushed barytes containing small quantities of muscovite as is typical in natural deposits. The centres of several golf balls were shown to contain essentially identical material. By contrast with previous reports, no zinc sulphide was found. The form and frequent location of the deposits in the conjunctiva as compared with cornea and eyelid is related to the structure of these tissues.
