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...

Background: Amiodarone is a drug that is used for treatment of cardiac arrhythmia after cardiac ischemia. This drug as b blocker decreases arrhythmia rate but it has many side effects on different tissues. Since there are rare reports about changes of lacrimal glands, this research has been carried out to study the morphological and ultrastructural changes of lacrimal gland cells after amiodaro...

Cysticercosis, a parasitic tissue infestation caused by larval cysts (cysticercus cellulosae) of the pork tapeworm, Taenia solium, most commonly affects the central nervous system, subcutaneous tissue, skeletal muscle, heart muscle, and the eye. Ocular adnexal infestation in cysticercosis can involve various sites within the eye like vitreous humor, subretinal tissue, extraocular muscle, and la...

Background: To report the clinical experience and analysis of our results with Ritleng intubation system in patients with congenital and acquired nasolacrimal duct obstruction. Methods: Silicone intubation with the Ritleng lacrimal system was performed in 17 patients (20 eyes) from March 2001 to March 2003 to relieve nasolacrimal duct obstruction following the failure of nasolacrimal duct probi...

LEUKAEMIC infiltration of the lacrimal sac is rare (Duke-Elder, 1952) and dacryocystitis due to leukaemic involvement of the sac has seldom been reported (Stokes, 1938; Busina, 1950). The number of cases recorded is increased when the reports of Sulzer and Duclos (1906), Pascheff (1927), and Weve (1928) are considered, but these authors described lymphomata of the sac without the typical blood ...

PURPOSE Dacryocystorhinostomy (DCR) is widely accepted as the procedure of choice for surgical correction of lacrimal drainage system obstruction distal to common canaliculus in adulthood. The success rate of DCR has been reported to be from 63% to 99%. DCR failure has been attributed to membranous occlusion of the rhinostomy site caused by soft tissue scarring. More recently, use of mitomycin ...

INTRODUCTION Injury is a known cause of monocular blindness. Ocular trauma may affect lacrimal canaliculi and the extraocular muscle. We report this case as it includes injury to lid, lacrimal canaliculi and inferior rectus. CASE DESCRIPTION A 25-year-old male presented with an injury caused by a sharp object that resulted in a conjunctival tear, lid tear involving the lacrimal canal, and rup...

PURPOSE The purpose of this study was to examine the histochemical distribution of carbonic anhydrase (CA) in lacrimal glands from rats and rabbits; and to determine if age- and/or sex-related differences exist in the amount and distribution of CA in the rat lacrimal gland. METHODS Lacrimal glands from young (3-12 wk) and aged (2-2.5 yr), male and female F344 rats and male rabbits were fixed ...
