The tip diameter of the standard Goldmann applanating prism was reduced from 7.0 mm to 4.0 or 4.5 mm, but the endpoint of intraocular pressure measurement-applanation of a circle of cornea having a diameter of 3.06 mm-was not changed. The "minified" tonometers exhibited standard mechanical calibration characteristics in three standard configurations. The 4.5-mm tonometer was calibrated for cynomolgus monkey eyes in vivo by open and closed stopcock manometry. By open stopcock manometry, between… CONTINUE READING
