Ultrasound parameters of normal lacrimal sac and chronic dacryocystitis

Ultrasound parameters of normal lacrimal sac and chronic dacryocystitis.

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...

Lectin cytochemistry of the lacrimal sac epithelium in experimental dacryocystitis.

PURPOSE To study the glycoconjugates in the lacrimal sac epithelium of Japanese white rabbits with experimentally induced chronic dacryocystitis. METHODS Chronic dacryocystitis was induced by a subcutaneous injection of albumin followed by an injection of Staphylococcus aureus into the lacrimal sac. The histological appearance of the lacrimal sac was studied using the alcian blue-periodic aci...

Structural changes in the lacrimal sac epithelium and associated lymphoid tissue during experimental dacryocystitis

PURPOSE To examine structural changes in the lacrimal sac epithelium and associated lymphoid tissue of rabbits with experimentally induced dacryocystitis. METHODS Experimental dacryocystitis was induced by an inoculation of Staphylococcus aureus into the lacrimal sac. The histological changes of the inflamed lacrimal sac epithelium and associated lymphoid tissue were studied by light and elec...

Lacrimal sac mucoepidermoid carcinoma.

A single case of mucoepidermoid carcinoma of the lacrimal sac was considered worth reporting as there are only four other cases described in the literature. The importance of the correct histological diagnosis and the management are discussed. This appears to be the first study of the ultrastructure of lacrimal sac mucoepidermoid tumour.
