title: Modified periodontal probe for simplified forced duction measurements.
abstract: A periodontal probe has been modified for use at surgery as a quantitative length-tension measuring device. It is simple and rapid to use, as well as inexpensive. In addition to zero length and tension, readings can be made at 25 g and 30 g of tension. Results of the test are described in four patients with restrictive or paralytic strabismus.
