purpose : to determine the association between retinal vascular diameter and its branching angles with diabetic retinopathy (dr) stages in diabetic patients methods : a descriptive analytic cross-sectional study was conducted in 62 diabetic patients (120 eyes) referred to farabi eye hospital between june 2008 and december 2009. digital fundus photography pictures were imported into photoshop so...

BACKGROUND AND PURPOSE Hemodynamics have been shown to play an important role in the initiation and progress of intracranial aneurysms, and are considered well-related to vascular configuration. The purpose of this study was to quantify the vascular geometry change due to intracranial stent placement and to discuss its potential effects on hemodynamics. MATERIALS AND METHODS Imaging data of p...

Purpose:To evaluate the vestibulocochlear symptoms and audiological findings in patients with radiologically detected vascular compression of abnormally localized vertebral artery at cerebellopontine angle. Materials Methods: Patients magnetic resonance imaging (MRI) an image due to angulated or lateralized included. The degree based on was noted by radiologist. patients’ medical records were i...

PURPOSE We aimed to investigate the angular changes after Y-stenting of the basilar bifurcation aneurysms. METHODS A total of 19 patients (age range, 27-80 years; mean age, 52.5 years) underwent Y-stent coiling for basilar bifurcation aneurysm. Three vascular angles (α, β1, β2) were measured in the anteroposterior plane. β1 and β2 represented the angles between the basilar artery and the prox...

The use of antibody to vascular endothelial growth factor to treat neovascular glaucoma yields good anatomic results in most cases. However, this type of glaucoma can cause angle closure with decompensation of intraocular pressure secondary to fibrovascular tissue contraction in the anterior chamber. Our surgical technique treats the cause by removing the anterior chamber fibrous complex after ...
