Dacryostenosis
Key Points
Dacryostenosis is either congenital or acquired. Symptoms include excessive tearing. Reflux of saline orfluoresceindye when flushing the lacrimal drainage system confirms the diagnosis. In congenital dacryostenosis, symptoms usually resolve by 9 months; manual decompression of the lacrimal sac may help. In acquired dacryostenosis, treat the underlying disorder. For both congenital and acquired dacryostenosis, surgery may be needed if symptoms persist.
