AIM:To compare the changes in excyclotorsion after inferior oblique(IO)recession in patients with primary and secondary inferior oblique overaction(IOOA).METHODS:We retrospectively analyzed the data obtained from patients with IOOA who underwent graded IO *** patients were followed up for at least 3 mo after *** photographs were taken preand postoperatively,and the sum of the angles of torsion in both eyes was used to analyze changes in *** were divided into two groups:those diagnosed with primary IOOA were enrolled in the 1’IOOA group,and those diagnosed with secondary IOOA caused by superior oblique palsy(SOP)were enrolled in the 2’IOOA *** before and after surgery were compared between the two ***:A total of 78 patients were enrolled in this study:34 eyes in the 1’IOOA group and 44 eyes in the 2’IOOA *** the 78 patients,torsional angle significantly decreased from 15.31°±7.40°to 12.11°±6.53°after IO recession(P<0.001).Mean preoperative torsional angle was larger in the 2’IOOA group than in the 1’IOOA group(P=0.03).In both groups,excyclotorsion significantly decreased after IO recession(P=0.001 and P<0.001,respectively);however,there was no significant difference in the amounts of changes in excyclotorsion between the two ***:Excyclotorsion is significantly larger in secondary IOOA than in primary IOOA,and a significant decrease in the torsional angle occurs after IO recession in both types of IOOA.

Dear Editor,Congenital retinal macrovessel (CRM) is defined as an abnormal large retinal vessel that encircles the foveal avascular zone (FAZ).Since the first description of a large aberrant vessel crossing the macula by Mauthnerin 1868,there have been several case reports about *** recently,Pichi et alreported clinical manifestations and multimodal retinal imaging of 49 eyes with *** their study,they had identified an association between macrovessel in the retina and venous anomalies of the brain and they emphasized the importance of systemic workups including brain magnetic resonance imaging (MRI).

The present paper investigates the effect of China＇s share of US imports on the aggregatelevel exchange rate pass-through to US import prices over the period from January 1999 to December 2008. The paper also focuses on the post-reform period, after 2005, allowing greater ftexibility of the RMB to explore the change in the role of the Chinese import share in determining the trend in the US exchange rate pass-through. Evidence reveals that China＇s share of US imports has a negative effect on the exchange rate pass-through. However, this negative effect has been moderated to a negligible level since China＇s exchange rate reform. An important implication is that the exchange rate flexibility of the RMB has been raised to a significant level may no longer cause distortion in the US competitive environment and prevent the USA from adjusting current accounts.
