BACKGROUND/AIM Until recently, diagnosis of disorders of the lacrimal system has depended on digital dacryocystography and on clinical examinations such as the fluorescein dye test, lacrimal probing, and irrigation. The lacrimal system and its mucous membranes can now be viewed directly with a lacrimal endoscope. While the first endoscopes were rigid and limited by poor picture quality in axial...
PURPOSE To study the practice of dacryocystorhinostomy (DCR) surgery by ophthalmologists in the United Kingdom (UK) looking at the evaluation techniques used, surgical variations, and follow-up management of DCR cases. METHODS A mail-shot questionnaire was designed and distributed to every UK consultant ophthalmologist on the specialist register held by the Royal College of Ophthalmologists. ...
PURPOSE To compare gene expression profiles of lacrimal gland duct and acinar cells after laser capture microdissection (LCM) and identify molecular networks related to K+ secretion, testing the hypothesis that duct cells are responsible for high K+ levels in tears. METHODS Frozen sections of lacrimal glands from five rats were subjected to LCM to isolate pure samples of duct and acinar cells...
Chronic graft-versus-host disease (cGVHD), a serious complication following allogeneic HSCT (hematopoietic stem cell transplantation), is characterized by systemic fibrosis. The tissue renin-angiotensin system (RAS) is involved in the fibrotic pathogenesis, and an angiotensin II type 1 receptor (AT1R) antagonist can attenuate fibrosis. Tissue RAS is present in the lacrimal gland, lung, and live...
Dacryocystorhinostomy (DCR) is the standard procedure for treatment of acquired nasolacrimal duct obstruction (NLDO), which can be performed with an external or endonasal approach. Numerous variations DCR have been described in literature that report varying rates success. The aim this study to describe approach and success rate DCR, nasal mucosa, bone lacrimal mucosa are sequentially removed.
Inflammation and impaired secretion by lacrimal and salivary glands are hallmarks of the autoimmune disease, Sjögren's Syndrome. These changes in the lacrimal gland promote dryness and inflammation of the ocular surface, causing pain, irritation and corneal damage. The changes that initiate and sustain autoimmune inflammation in the lacrimal gland are not well-established. Here we demonstrate t...
PURPOSE To describe the change of lacrimal gland volumes in Korean patients with thyroid-associated ophthalmopathy (TAO) via computed tomography (CT). METHODS A retrospective review of CT images from 217 TAO patients and 135 control subjects was performed. The TAO patients were diagnosed between May 2005 and May 2014 and had a CT performed on initial presentation (330 orbital CT scans). These...
A 40-year-old woman presented with vague headaches and blurred vision. Contrast-enhanced magnetic resonance imaging of the brain revealed bilaterally symmetrical diffuse enlargement of the lacrimal glands. A fine needle biopsy of the lacrimal gland was consistent with sarcoidosis. Although, isolated lacrimal gland involvement is rare, it may be the initial clinical presentation of sarcoidosis, ...
BACKGROUND Pyogenic lacrimal gland abscesses are uncommon and thus may not be immediately clinically recognized without a high index of suspicion. FINDINGS We present two patients with preseptal cellulitis and characteristic low-attenuation fluid collections in the lacrimal glands demonstrated on computed tomography (CT). CONCLUSIONS Lacrimal gland abscesses should be considered when dacryo...
