DOS Times Vol. 12, No. 10 April, 2007 Congenital nasolacrimal duct obstruction is the most common cause of epiphora in children. In the majority of cases, it is due to an obstruction at the lower end of the NLD. The Ophthalmologist should have the throrough understanding of the developmental anatomy, abnormalities of the nasolacrimal system and other congenital disorders for appropriate diagnos...

The eye has two sets of structures that produce tears. Smaller tear glands help maintain a baseline level of moisture on the surface of the eye. Unfortunately, inflammatory conditions like rheumatoid arthritis, Sjogrens disease as well as aging and menopause lead to decreased tear production. As tear production diminishes, the surface of the eye starts to dry out. Further, inflammation of the o...

Background: Obstruction of the nasolacrimal duct is the most common abnormality of the lacrimal system in childhood leading to epiphora. It is found in about 20% of newborns. If not treated in time, it may be complicated by recurrent conjunctivitis, chronic dacryocystitis, and lacrimal abscess formation. Objectives: To study the outcome and complications of probing for congenital nasolacrimal d...

Introduction :The therapeutic approach in children with Nasolacrimal duct obstruction (NLDO)differs from that used in adults. While Dacryocystorhinostomy(DCR) is the most common procedure in adults. It is carried out less frequently in children. It is indicated for children with persistent NLDO refractory to probing and in cases of recurrent or chronic dacryocystitis. Aims and objectives : The ...

Introduction Mucoceles are benign expansive cystic formations, composed of a mucus-secreting epithelium (respiratory or pseudostratified epithelium). Nasolacrimal mucocele occurs in a small proportion of children with nasolacrimal duct obstruction and is characterized by a cystic mass in the medial canthus with dilation of the nasolacrimal duct; although dacryocystoceles are rare in adults, the...

PURPOSE To evaluate the nasolacrimal duct reconstitution with radio frequency for restoration of lacrimal flow in cases of nasolacrimal duct obstruction. METHODS The procedure was carried out in 16 eyes of 16 patients (13 women and 3 men) by the same surgeon, with monopolar high-frequency device at 450 kHz and 150 W, with local anesthesia under sedation. Inclusion criteria were lower lacrimal...

PURPOSE Dacryoscintigraphy is widely known to be an effective modality in diagnosing abnormalities of the lacrimal system that cause epiphora (pathological overflow of tear). However, dacryoscintigraphy rarely serves beyond the simple diagnostic use for lacrimal duct obstruction. In our study, dacryoscintigraphy results of patients with functional lacrimal duct obstruction are newly classified ...
