purpose: to compare clinical and confocal scan outcomes after descemet stripping automated endothelial keratoplasty (dsaek) performed for fuchs’ endothelial dystrophy versus pseudophakic bullous keratopathy. methods: in this retrospective comparative study, 47 consecutive eyes of 39 patients with the diagnosis of fuchs’ endothelial dystrophy (n=29, group 1) or pseudophakic bullous keratopathy (...

purpose: to report the outcomes of manual lamellar keratoplasty (lkp) in patients with delayed-onset mustard gas keratitis (mgk) and compare visual outcomes between subgroups with simultaneous or sequential klal and lkp. methods: in this retrospective, interventional study, 52 eyes of 37 male survivors of chemical warfare with mgk who underwent lkp were included. the results were evaluated with...

OBJECTIVE To evaluate the outcome of repeated intravitreal injections of triamcinolone acetonide for the treatment of exudative age-related macular degeneration. METHODS This prospective, comparative nonrandomized clinical interventional study included 13 patients with progressive exudative age-related macular degeneration with occult, or predominantly occult, subfoveal neovascularization. Al...

looks set to come under increasing challenge this fall as a senior Republican, the Senate majority leader, Bill Frist, said this summer he would support legislation to remove some of the administration's limitations on such research. The move is likely to result in a showdown between the president and the Senate. Frist, a heart and lung transplant surgeon, and a close ally of the president, had...

PURPOSE To describe the cumulative 5 year incidence of visual field loss in adult Chinese in Greater Beijing. METHODS The Beijing Eye Study 2006 included 3251 subjects (mean age 60.4±10.1 years) who had participated in the Beijing Eye Study 2001 and returned for re-examination. All participants underwent a comprehensive eye examination, including visual field test by frequency doubling thresh...

Using a synthetic method, the phase behavior of CO2 (1) + cyclooctane (2) binary system was for first time experimentally studied between 292.95 K and 373.55 K. In this temperature range, bubble- dew-point pressures, ranging from 13.2 to 183.4 bar were measured carbon dioxide mole fractions 0.1014 0.9701. A total 96 experimental data points acquired. The obtained using high-pressure cell by vis...

the present study aims to investigate the system of the visual transitivity by analyzing the images of american english file (2014) and cutting edge (2005) series based on halliday’s (1976) systemic functional linguistics and kress and van leuween’s (1997-2006) social semiotics. the system of visual transitivity refers to a type of process which determines how represented participants are label...

among abundant image denoising methods proposed so far, the use of patchbased algorithms have attracted a lot of attention from image processingcommunity. although these methods are very powerful in presentation of highquality results, the impact of human visual system (hvs) is ignored in sole of them.in this paper the human visual geometry is used in preparation of a new method forimage denois...

OBJECTIVE To determine the effect of posterior capsulotomy on macular thickness, intraocular pressure and endothelial cell loss in pseudophakic patients with posterior capsule opacification using the other eye of every patient as a control. METHODS An observational prospective study was conducted on 31 pseudophakic patients with posterior capsular opacification in one eye, using the other eye...
