To acertain the diagnosis the following examinations must be made: a slitlamp examination of the lacrimal puncta, of the conjuctiva and of the anterior segment of the globe (Busse and Hollwich, 1978), the 'lacrimal punctum excursion test' (Jtinemann and Schulte, 1974), the diagnostic irrigation of the lacrimal passage (Bangerter, 1953), the nasal dye test (Fischer, 1918), the canaliculus test (West, 1918), the Jones test I and II (Jones, 1966), the standardized A-scan echography (Rochels et al, 1984) and the dacryocystography (Figure 9, 12) (Aubaret, 1911;Szily, 1914;Busse et al, 1979;Gullotta and Denffer, 1980).
