Imperforate puncta with blocked naso-lacrimal duct.
The isolated anomaly of imperforate lacrimal puncta was noted by Zehender (i867, I883). Similarly, blockage of the naso-lacrimal duct was noted by Crigler (1923) and Guerry and Kendig (1948), the anomaly usually being due to failure in canalization. The simultaneous occurrence of these two anomalies would appear to be very rare (Fig. i) and an extensive search of the literature has revealed onl...
متن کاملCharacterization of mucins in human lacrimal sac and nasolacrimal duct.
PURPOSE Mucins are polymers that may reduce drag and enhance tear outflow. Mucin expression and distribution in human efferent tear ducts were tested in the physiological state, and potential differences in the expression pattern were investigated in the presence of primary acquired dacryostenosis (PANDO). METHODS Expression of mucins in human lacrimal sac and nasolacrimal ducts was monitored...
متن کاملEpiphora and the bony naso-lacrimal canal.
IT is possible to obtain a radiographic view of the naso-lacrimal canal "end-on" by directing a beam of x-rays down the axis of the canal to a film held horizontally in the mouth: the centre of the film is placed near the site of the first molar tooth (Brunetti, 1930; Kopylow, 1930; Toth, 1933), or the second pre-molar. Examples of such radiographs are shown in Figs 1, 2, and 3. The present inv...
متن کاملImaging Features of Malignant Lacrimal Sac and Nasolacrimal Duct Tumors.
The purpose of this study was to present the imaging features of primary and secondary malignant lacrimal sac and nasolacrimal duct tumors and their pattern of tumor spread in 18 patients. The most common tumor histology in our series was squamous cell carcinoma. In 15/18 patients, tumor involved both the lacrimal sac and duct at the time of diagnosis. In 11/16 patients on CT, the nasolacrimal ...
متن کاملLacrimal 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.
