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 کاملA study of clinico Pathological Correlation of Naso lacrimal duct obstruction
Objective: To study the age and the sex distribution among the primary and secondarily acquired Nasolacrimal duct obstruction . Methods: we conducted a prospective observational study among randomly selected 100 patients presented with epiphora to ENT department during 2year period ie; from march 2013-march 2015. After confirming presence of Nasolacrimal duct obstruction (NLDO) by opthalmologic...
متن کاملEnd-to-side Anastomosis for Obstruction of the Naso-lacrimal Duct.
IN all the operations commonly performed for obstruction of the nasolacrimal duct, the side of the sac, and not the end, is used for the anastomosis (Fig. 1). The medial wall of the sac is incised vertically over the greater part of its extent to provide the anterior and posterior flaps. This radically alters the anatomy and destroys any chance of pumping action by the orbicularis. The upper en...
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 کاملCongenital fistula of lacrimal duct.
CONGENITAL fistula of the lacrimal duct is very rare, and is usually associated with other congenital anomalies (Duke-Elder, 1932, 1952; Gray, 1949; Spaeth, 1948). The epithelium of the ducts and alveoli of the lacrimal gland is derived from a series of ectodermal invaginations in the region of the superior conjunctival fornix. Early buds form the orbital portion, while secondary buds from abov...
