introduction: according  to  the  latest  statistical  and  epidemiological  studies,  copd  will  become  the  fourth  leading  cause  of  death  in  2030  worldwide.  scientists  are  studying  on  methods  to  diagnose  copd  in  the  patients  in  early  stages,  because  it  is  a  curable  and  preventable  disease  in  early  stages.  in  this  study,  evidences  of  hyperinflation  on  ...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

conclusions although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inev...

Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...

purpose: to evaluate the histopathologic features of trabeculectomy specimens and the results of tra-beculectomy in relation with these features in patients with chronic primary glaucoma. methods: this interventional case series included 30 eyes of 28 patients with primary chronic glaucoma who underwent trabeculectomy between 2004 and 2006. each case was followed for 6 months post-operatively. ...

PURPOSE To evaluate the characteristics of peripheral anterior synechiae (PAS) in primary angle-closure glaucoma (PACG). METHODS We reviewed the charts of 155 patients (244 eyes) with PACG. We divided these patients into one of four clinical subtypes: acute angle-closure glaucoma (ACG), chronic ACG, angle-closure hypertension, and ACG suspect. The prevalence, extent, and location of PAS were ...

A study of the postoperative evolution of 70 eyes subjected to trabeculectomy over a 3-year period is reported. This is the operation of choice in our department in cases of chronic open-angle glaucoma and chronic angle-closure glaucoma. The study showed that in 35.7% of the operated eyes the intraocular pressure was increased on the second postoperative day and became normal within a week. Thi...

Three groups of patients (those with chronic open-angle glaucoma, glaucoma suspects, and normals) were subjected to both tonography and suction cup analysis. The data, analyzed by an electrical model of the eye, showed that (1) venous pressure opposing aqueous outflow is higher in patients with chronic open-angle glaucoma and in glaucoma suspects than in normal patients; and (2) lack of pressur...
