Development of training aids for the simplified W.H.O. trachoma grading system. A preliminary note.
A simplified scheme for the grading of trachoma and its complications has been developed by the W.H.O. Programme for the Prevention of Blindness. This scheme has been field-tested in several countries, and the results have demonstrated a good observer agreement. The development of training aids for the use of this scheme by non-specialist health personnel is in progress. This will include a slide series, two manuals for the clinical examination and for the analysis of the reliability of results obtained, plus a simple trachoma grading card for field staff. It is envisaged that these aids will be available as from 1991, and that they will allow a number of countries to set up a system for regular surveillance and evaluation of trachoma.
