Definitive Treatment of Congenital Lacrimal Sac Fistula

Abstract

The procedure we describe is believed to be a rational and effective approach to the rare but preplexing problem of congenital lacrimal sac fistula. The procedure is based on the principles of: (1) definite location of the lacrimal sac for protection of canaliculi and sac through probe insertion; (2) fastidious dissection of the tract to its base; and (3) positive testing of the suture and sac site for leakage.
