The lacrimal system is comprised of the lacrimal glands for tear production and the lacrimal drainage system for draining tears away from the eyes. Congenital lacrimal system anomalies other than nasolacrimal duct obstruction are uncommon. Congenital lacrimal fistulae are a rare developmental anomaly, and when they occur, they are usually unilateral. Fistulae and diverticulae can originate from...

BACKGROUND High-frequency B scan ultrasonography is a proven method for the assessment of anterior segment diseases. Only few studies have used sonography to examine the lacrimal drainage system. We examined the proximal lacrimal drainage system by high-resolution 20-MHz ultrasound to verify the possibility to identify intracanalicular lacrimal plugs. METHODS Eight patients who had received 1...

OBJECTIVE Myiasis is the invasion of human tissues by Diptera larvae. Ocular involvement is uncommon. Trauma is the major cause of lacrimal apparatus lesions. However, it is rarely associated with parasitic infestation. The objective of this paper is to report a case of canalicular laceration caused by Dermatobia hominis larva. DESCRIPTION An eight-year-old girl presented preseptal cellulitis...

BACKGROUND Rupture of the medial canthal ligament can be caused by many events. It remains a challenge to rebuild the drainage system and restore the function. The aim of this study was to evaluate the clinical efficacy of medial canthoplasty combined with conjunctivodacryocystorhinostomy (CDCR) in patients with medial telecanthal deformities and lacrimal drainage system damage. METHODS Twent...

AIM It appears from the literature that no standardised examination exists for patients with functional nasolacrimal duct obstruction. The role of dacryocystography and lacrimal scintigraphy was compared in the diagnosis and management of these patients. METHOD Patients who were clinically diagnosed as having unilateral or bilateral functional nasolacrimal duct obstruction were prospectively ...

Lacrimal punctal agenesis is a rare cause of congenital epiphora and may occur in isolation or in combination with other lacrimal drainage anomalies such as pathologies of the canaliculus, lacrimal sac, and nasolacrimal duct. It rarely occurs in a familial manner. If diagnosed earlier, management of this condition may be as simple as a sharp opening or may necessitate more complex interventions...

Purpose: In epiphora, dacryocystography (DCG) is established for localization of underlying dacryostenosis. DCG is of limited value concerning the depiction of periductal structures, and does not provide functional information e.g. in dysfunction of the canalicular muscle pump or relative stenoses for reasons of active instillation of the contrast agent. Dacryoszintigraphy provides sufficient f...

Dear Editor, Two cases with epiphora and medial canthal mass showed a cyst within the lacrimal sac that compressed the lacrimal drainage system. We describe a new lacrimal sac anomaly of lacrimal intrasaccal cyst, which has not yet been reported. A 31-year-old woman was referred for epiphora in her left eye for 17 years. She also presented with a 10-year history of a palpable mass below the med...
