The Crigler method was effective in managing congenital nasolacrimal duct obstruction cases.

A Survey of Management of Congenital Nasolacrimal Duct Obstruction by Pediatric Primary Health Care Providers in Spain

“…The lacrimal duct is the last to canalize during development (5) and the membrane can spontaneously open within several weeks of birth, before the onset of lacrimation. Often the child needs to be maintained with massage to empty the sac or hydrostatic massage (Crigler massage) (6,13,17,18).…”

“…Congenital nasolacrimal duct obstruction (CNLDO) due to an imperforate membrane at Hasner valve is the most common abnormality of the lacrimal system in childhood (1,2). The incidence of CNLDO varies from 1.75% (1) to 6%-12% (3) to 20%-30% (4, 5) of normal newborns (6). Only Society in Castilla-León, Spain (APAPCYL).…”

Dilatação por cateter-balão (dacrioplastia) para tratamento das obstruções congênitas do ducto lacrimonasal

“…A dacrioestenose congênita pode ser tratada inicialmente de forma conservadora porque as obstruções podem se resolver espontaneamente no primeiro ano de vida (2) . Massagem digital de Crigler e colírios antibióticos são os mais recomendados inicialmente (3)(4) . Para crianças com lacrimejamento persistente, uma simples sondagem do ducto lacrimonasal pode ser terapêutica em 90% dos casos (5)(6) .…”
