IN the vast majority of cases the aetiology of an acquired obstruction in the lacrimal drainage apparatus remains obscure. Overt infection is a common associate, especially with obstructions involving the naso-lacrimal duct. It is still not clear whether the infection is causal or sequential to the obstruction, or whether these two factors are simply part of a wider diathesis. At the present ti...

PURPOSE This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions. METHODS Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coate...

Dear Editor, The causes of epiphora can be separated into two categories: (1) reflex epiphora, which is caused by surface damage to the eye or infectious ocular disease, and (2) lacrimal pumping failure, which is caused by anatomical and functional failure in the outflow tract due to abnormal position of the lacrimal puncta or closure of the nasolacrimal duct [1,2]. The abnormal position of the...

Abstract Background Involvement of lacrimal apparatus by Non Hodgkin lymphoma as a first manifestation is extremely rare and only three cases have been reported in children. The purpose of this report is to determine the clinical characteristic of patient with primary involvement of lacrimal apparatus with lymphoma. Case presentation A 7-year-old girl with history of tearing, gradually prog...

AIM To compare the diagnostic information provided by digital subtraction dacryocystography (DCG) and syringing of the nasolacrimal system in patients with epiphora. METHODS Twenty-five lacrimal systems of 17 patients, who presented with unilateral or bilateral epiphora and no concurrent ocular or lid abnormality, were prospectively entered into the study. The patients initially underwent syr...

PURPOSE To evaluate the outcome of the external dacryocystorhinostomy with and without suturing the posterior mucosal flaps. METHODS This study included 106 patients with lacrimal drainage system disorders who underwent the external dacryocystorhinostomy. Fifty four patients (Group A) underwent external dacryocystorhinostomy with suturing anterior and posterior flaps of the lacrimal sac and n...

BACKGROUND Endoscopic extended maxillary mega-antrostomy (EMMA) is a mucosal sparing technique that allows maxillary drainage by gravity, with a reported symptomatic nasolacrimal duct injury incidence of 0-4%, based on history alone. Injury to the nasolacrimal duct is known to cause epiphora, a complication that is rare but more often seen in this revision surgery. OBJECTIVE The goal of this ...
