Purpose: To investigate the clinical features and prevention of ocular injuries associated with the mistaken use of superglue as eyedrops. Methods: Medical records of 13 patients with ocular superglue injury who visited our hospital from January 1, 2002 to December 31, 2004 were analyzed. The clinical features of ocular superglue injury and causes of using superglue instead of eyedrops for each patient were analyzed. Results: The present study involved 15 eyes of 13 patients, including seven men (53.8%) and six women (46.2%), ranging from 6 to 72 years of age, with a mean age of 38.4 years. Ocular superglue injuries were corneal abrasion in all patients. The bonding of eyelids (eight cases, 61.5%) and eyelashes (two cases, 15.4%) were identified. Ocular injuries were treated conservatively and resolved without complications. The major cause of mistaken use of superglue was similarly packaged eye drops (11 cases, 84.6%). Other causes included poor eyesight (one case) and unsupervised children (one case). Conclusions: The availability of eyedrops in various ocular diseases has recently increased, and superglue is found in many households, wherefore incidence of ocular superglue injuries can increase. Therefore, modifying the design of superglue bottles and providing proper education for patients to prevent ocular superglue injury is important. J Korean Ophthalmol Soc 2010;51(10):1398-1402

With uniform heat generation from the inner surface of the cylindrical heater placed in a cross flow boundary condition, heat flow that is conducted along the wall of the heater creates a non-isothermal surface temperature and non-uniform heat flux distribution. In the present investigation, the effects of circumferential wall heat conduction on convection heat transfer is investigated for the case of forced convection around horizontal circular tube in cross flow of air. The wall conduction number which can be deduced from the governing energy equation should be used to express the effect of circumferential wall heat conduction. It is demonstrated that the circumferential wall heat conduction influences local Nusselt numbers of one-dimensional and two-dimensional solutions.
