ABSTRACT
This work aimed to study the role of dacryocystography in the management of congenital epiphora. Twenty-four dacryocystograms of 17 children with congenital epiphora showed bilaterally of the disease in 41% of the cases. The site of obstruction was found in nasolacrimal duct. The obstruction was detected in 58.34% of the eyes in upper part of nasolacrimal duct and in 41.66% in its lower part. Lipiodol injection could relieve 33.3% of the obstructions and probings was successful in 50% while 16.7% of the obstructions did not improve. It was concluded that dacryocystography is an essential investigation in congenital epiphora. The lower the obstruction of nasolacrimal duct the better the prognosis. Lipiodol injection alone could relieve 33.3% of the affected eyes. 28.6% of the eyes with upper nasolacrimal duct obstruction were resistant to probing and need dacryocystorhinostomy
