Mobility support for Internet devices is quite important for consumer electronics and the number of the handled device is growing up quickly. However, the IP addresses are not enough for the number of the rapidly grow devices in the All-IP generation. So the IPv6 is adopted to solve these problems. Our purposed structure is based on the IEEE 802.11. However(More)
PURPOSE To evaluate the relationship between lens position parameters and intraocular pressure (IOP) reduction after cataract surgery in patients with primary open-angle glaucoma (POAG) and in nonglaucomatous patients. METHODS The main outcomes of this prospective study were percent and absolute IOP change, which were calculated using the preoperative IOP(More)
PURPOSE To compare optic nerve head (ONH) morphology of optic nerve atrophy between eyes with primary open-angle glaucoma (POAG) and eyes with a history of nonarteritic anterior ischemic optic atrophy (NAION) using enhanced depth imaging (EDI) with spectral-domain optical coherence tomography (SD-OCT). METHODS In this cross-sectional study, 121 eyes of 91(More)
PURPOSE The efficacy and sufficiency of a healthcare system is directly related to the knowledge and skills of graduates working in the system. In this regard, many different assessment methods have been proposed to evaluate various skills of the learners. Video Observation of Procedural Skills (VOPS) is one newly-proposed method. In this study we aimed to(More)
PURPOSE To evaluate different mechanisms of primary angle closure (PAC) and to quantify anterior chamber (AC) parameters in different subtypes of angle closure disease using anterior segment optical coherence tomography (AS-OCT). METHODS In this prospective study, 115 eyes of 115 patients with angle closure disease were included and categorized into three(More)
PURPOSE To compare long term efficacy of phacoemulsification in the early management of acute primary angle closure (APAC) after aborting an acute attack and performing laser peripheral iridotomy (LPI). METHODS In this nonrandomized comparative prospective study, we included 35 subjects presenting with APAC who had responded to medical treatment and LPI(More)
