Dear Editor, Recently, we experienced two cases of lacrimal sac tumors discovered in patients who presented with persistent epiphora after receiving dacryocystorhynostomy (DCR). A 75-year-old female visited the clinic complaining persistent epiphora in the right eye for 5 years. The patient was diagnosed with nasolacrimal duct obstruction in the right eye and received a DCR twice 2 years ago at...

BACKGROUND Decreased lacrimal gland output may cause dry eye syndrome. Using a rat model, we examined the feasibility of transplanting lacrimal gland cells from newborns. OBJECTIVES To restore lacrimal gland function in eyes with compromised tear production. METHODS A model of dry eye in adult rats was developed by unilateral surgical removal of the main lacrimal gland. Tear secretion in bo...

The purpose of this study is to evaluate the effectiveness of endoscopic dacryocystorhinostomy by the posterior lacrimal sac approach without use of lacrimal stents or harvest of mucosal flaps as a valid surgical procedure for the treatment of an obstruction of the lacrimal pathways. A retrospective evaluation was conducted in a cohort of 75 patients between 2007 and 2011. A total of 78 endosco...

Chronic graft-versus-host disease (cGVHD) is a major complication of hematopoietic stem cell transplantation. Dry eye disease is the prominent ocular sequel of cGVHD and is caused by excessive inflammation and fibrosis in the lacrimal glands. Heavy chain-Hyaluronan/Pentraxin 3 (HC-HA/PTX3) is a complex purified from human amniotic membrane (AM) and known to exert anti-inflammatory and anti-scar...
