PURPOSE To compared the ultrasound findings of the lacrimal sac between subjects with normal lacrimal systems those with chronic dacryocystitis. METHODS A retrospective study of 10 subjects with a normal lacrimal system (Group 1) and 10 with chronic dacryocystitis (Group 2) diagnosed according to B-mode ultrasound with a 10-MHz transducer and the direct-contact technique (AVISO, Quantel Medic...

PURPOSE To evaluate the prophylactic use of antibiotics in external dacryocystorhinostomy for the prevention of postoperative complications. METHODS This study included 697 patients diagnosed with distal nasolacrimal duct obstruction and who were operated on by the same surgeon. Direct culture of the lacrimal sac content was carried out. Data were collected regarding clinical signs and sympto...

Purpose: To investigate whether neonatal dacryocystoceles and dacryocystitis are associated with nasolacrimal duct cysts, and to report the outcomes of treatment of these disorders. Methods: This was a retrospective medical record review of two groups of infants with nasolacrimal duct (NLD) obstruction. The first group had dacryocystoceles with or without dacryocystitis. The second group had NL...

OBJECTIVE To compare the efficacy of external dacryocystorhinostomy (DCR) with and without intraoperative application of mitomycin-C in patients with chronic dacryocystitis. STUDY DESIGN An experimental study. PLACE AND DURATION OF STUDY Department of Ophthalmology, Bahawal Victoria Hospital (BVH), Bahawalpur, from September 2009 to December 2010. METHODOLOGY One hundred and sixty patient...

LEUKAEMIC infiltration of the lacrimal sac is rare (Duke-Elder, 1952) and dacryocystitis due to leukaemic involvement of the sac has seldom been reported (Stokes, 1938; Busina, 1950). The number of cases recorded is increased when the reports of Sulzer and Duclos (1906), Pascheff (1927), and Weve (1928) are considered, but these authors described lymphomata of the sac without the typical blood ...

The lacrimal drainage system consists of the puncta (upper and lower within the eyelids) which are the opening to the upper and lower canaliculus. These meet at the common canaliculus and open into the lacrimal (tear) sac. This runs parallel to the nose and is separated from the middle meatus of the nasal cavity by two thin plates of bone. It continues down to become the nasolacrimal duct (tear...

DACRYOCYSTORHINOSTOMY, the operation of choice in chronic dacryocystitis, is performed in almost all cases in this clinic by a special technique. Toti (1904) first described the drainage of the lacrimal sac by removal of the bony wall. Kuhnt (1914) stitched the nasal mucosa to the periosteum. Ohn (1920) first sutured the nasal mucosa to the sac. The operation was modified by Dupuy-Dutemps and B...
