作者： marlene Thorn Taber Ph D

Having spent five years in Ukraine and Russia eating pelmeni (a kind of jiaozi) and vareniki(dumplings), teaching English sometimes, teaching dance a lot and lecturing about the privatization of theater and intellectual property, it was time to find warmer places to work. Why I thought China would be less cold is hazy, but(continued)

In the spring of 2004, Xu Ying accompanied Campbell Britton, a female teacher working on her doctorate from the University of California, Los Angeles (UCLA) to a classroom at the National Academy of Chinese Theatre Arts. She was there to give some lectures about theatre in Brazil; he was there as an alumnus of the academy and as a friend of Campbell, having met her when he was a guest professor of Chinese Opera at UCLA.

AIM：To describe a novel technique of creating a landing strip within the trabecular meshwork to guide trabecular micro-bypass stent（iStent） implantation in patients who underwent ***：Thirty-four eyes from 30 patients who underwent i Stent implantation after phacoemulsification from May 2014 to February 2015 were included in our retrospective study. All iStents were implanted via the ＂landing strip＂ technique. A 25-gauge microvitreoretinal blade was used to bisect the trabecular meshwork to less than 1 clock-hour, effectively creating a landing strip. The iStent applicator was pressed along the landing strip and then the stent was released into the trabecular meshwork. RESULTS：Of the 34 eyes with iStent implantation, 27（79.4%） eyes had primary open-angle glaucoma, 6（17.6%） eyes had pseudoexfoliation glaucoma, and 1（2.9%） eye had ocular hypertension. At 6-month follow-up（n=17）, the mean number of hypotensive medications decreased from 2.2±1.2 at baseline to 0.8±1.3（P=0.05） and mean intraocular pressure decreased from 19.7±4.1 mm Hg at baseline to 16.7±2.1 mm Hg（P=0.58）. Two eyes（5.9%） required subsequent trabeculectomy. CONCLUSION：The ＂landing strip＂ technique appears to be an effective way to assist with iS tent implantation.
