This paper deals with the traffic factors related to the collisions of circular intersections. The purpose of this study is to develop traffic accident models by type of collision based on land use. In pursuing the above, the traffic accident data from 2010 to 2014 were collected from the "Traffic Accident Analysis System (TAAS)" data set of the Road Traffic Authority. A multiple regression model was utilized in this study to develop the traffic accident models by type of collision. 17 explanatory variables such as geometry and traffic volume factors were used. The main results are as follows. First, the null hypothesis that the type of land use does not affect the number of accidents by type of collision is rejected. Second, 10 accident models by type of collision based on land use are developed, which are all statistically significant. Finally, the ADT, inscribed circle diameter, bicycle lane, area of central island, number of speed hump, circulatory roadway width, splitter island, area of circulatory roadway, mean number of entry lane and mean width of entry lane are analyzed to see how they affect accident by type of accident based on land use.

Purpose: To report a case of ciliary body tuberculoma, which induced scleral melting. Case summary: A 32-year-old man, who was diagnosed with miliary pulmonary tuberculosis 1 week earlier, presented with a conjunctival injection and mass on his right eye 3 months in duration. On excisional biopsy, melted sclera and exposed uveal tissue were found; acid-fast stain was positive. Two months after anti-tuberculosis treatment, anterior granulomatous uveitis and granuloma formation on the anterior chamber angle developed. A low-dose systemic steroid therapy was added. Six weeks after systemic steroid therapy, anterior uveitis and granuloma on anterior chamber angle disappeared. Conclusions: We experienced a case of ocular tuberculosis on the ciliary body. A low-dose systemic steroid along with multi-drug anti-tubercular therapy may be an effective treatment of ciliary body tuberculoma.

Purpose: To report a case of unilateral Purtscher’s retinopathy that spontaneously resolved within 24 hours. Case summary: A 54-year-old man presented with decreased visual acuity in his left eye after a vehicle accident. When the accident occurred, his chest region was compressed by the safety belt. The case was diagnosed with Purtscher’s retinopathy based on fundus examination, flourescein angiography (FAG) and optical coherent tomography (OCT). At presentation, the best corrected visual acuity (BCVA) was 0.3 in the affected eye. Tiny Purtscher-flecken and macular edema were observed but there was no sign of retinal hemorrhage. Immediately after the trauma, OCT detected abnormally increased hyperreflectivity in the nerve fiber layer and ganglion cell layer, severe cystoid edema and serous foveal detachment. Without any treatment, BCVA was improved to 1.0 within 12 hours. Recovery of visual acuity was followed by improvement of abnormal hyperreflectivity in the nerve fiber layer, cystoid macular edema and serous foveal detachment. Conclusions: The authors of the present study report a dramatically resolved unilateral Purtscher’s retinopathy after blunt chest trauma. J Korean Ophthalmol Soc 2012;53(9):1341-1345
