METHODS: Forty-two orbits and BNLCs from 21 Asian cadavers (9 men and 12 women; average age at death, 84.4 years; range, 70–99 years) had been fixed in 10% buffered formalin before use. After exposing the LF and the medial half of the BNLC, the authors measured the angles of the longitudinal axis of the LF and the BNLC relative to the aesthetic horizontal plane respectively. Based on these values, the relative orientation of the LF and the BNLC was determined and defined in terms of [DELTA] BNLC-LF. A positive [DELTA] BNLC-LF represents a nasolacrimal canal that descends posteriorly relative to the LF. RESULTS: The mean LF, BNLC, and [DELTA] BNLC-LF were 9.5°, 19.8°, and 10.3°, respectively. In 39 passages (92.9%), the [DELTA] BNLC-LF was positive, representing a nasolacrimal canal that is more posteriorly oriented than the LF. In 3 passages (7.1%), the [DELTA] BNLC-LF was equal to or less than 0°; 2 of them (4.8%) had a straight course and 1 passage (2.4%) had a negative value. CONCLUSIONS: In most patients, the BNLC is directed more posteriorly than the LF. This finding may help in preventing an inadvertent false passage during probing and intubation in patients with epiphora. 2011-12-31T13:30:00Z http://hdl.handle.net/2440/77705 Title: IgG4-related orbital disease: a meta-analysis and review Author: Andrew, Nicholas Howard; Kearney, Daniel John; Selva-Nayagam, Dinesh Niranjan Abstract: IgG4-related orbital disease (IgG4-ROD) is a recently described condition that may account for a significant proportion of idiopathic lymphoplasmacytic or sclerotic orbital lesions. This study is the first meta-analysis of published cases and reveals several differences between IgG4-related disease affecting the orbit and that affecting the pancreas. IgG4-ROD affects a slightly younger group of patients, affects men and women approximately equally, is commonly associated with salivary gland lesions, is associated with a relatively higher serum IgG4 and may confer an increased risk of non-Hodgkin Lymphoma. Its pathogenesis may involve an immune response to antigen exposure in the upper aerodigestive tract. 2011-12-31T13:30:00Z http://hdl.handle.net/2440/77662 Title: Horner Syndrome: a practical approach to investigation and management Author: Gao, Zoe Weizhi; Crompton, John Lionel 2011-12-31T13:30:00Z http://hdl.handle.net/2440/77463 Title: Pilot randomized trial of a nanopulse retinal laser versus conventional photocoagulation for the treatment of diabetic macular oedema Author: Casson, Robert James; Raymond, Grant Leslie; Newland, Henry Simpson; Gilhotra, Jagjit Singh; Gray, Timothy Lewis 2011-12-31T13:30:00Z
