purpose : the aim of this study is to measure the endogenous cortisol levels in the patients with central serous chorioretinopathy (cscr) and also, evaluate the short-term effect of oral ketoconazole in the treatment of both acute and chronic cscr. methods : in this prospective interventional case series 12 patients with acute cscr and 7 patients with chronic cscr (including one patient with bi...

purpose : to determine the nerve fiber layer and macular thickness by optical coherence tomography (oct) in emmetropic, high-myopic and high-hyperopic eyes methods : one hundred five eyes of 55 randomly selected healthy subjects between 20 and 30 years old were included in this study. the eyes were categorized in three groups (high-myopic, emmetropic and high-hyperopic) according to their cyclo...

purpose: to measure peripapillary retinal nerve fiber layer (rnfl) thickness in normal human eyes by optical coherence tomography (oct). methods: eighty-one eyes of 45 normal participants were studied. each person underwent a complete ophthalmic examinations, including measurement of visual aquity and intraocular pressure and evaluation of the anterior segment, optic disc, and retinal nerve fib...

purpose: to determine peripapillary retinal nerve fiber layer (rnfl) thickness by three-dimensional optical coherence tomography (3d-oct) in a normal iranian population and to evaluate the concordance of these measurements with those obtained by the second generation of optical coherence tomography (oct ii). methods: in a cross-sectional observational study, 96 normal iranian subjects 20-53 yea...

BACKGROUND No reports exist concerning in vivo optical coherence tomography visualization of the epidural space and the blood patch process in the epidural space. In this study, we produced real-time two-dimensional and reconstructed three-dimensional images of the epidural space by using optical coherence tomography in a porcine model. We also aimed to produce three-dimensional optical coheren...

Abstract: Optical coherence tomography is a non-invasive method of imagining the anterior and posterior segment eye. It commonly used in ophthalmic practice to diagnose monitor various pathologies eyeball. angiography (OCTA) useful tool visualize entire retinal choroidal microvasculature, allowing assessment perfusion without intravenous dye administration.

INTRODUCTION AND OBJECTIVES The clinical benefits of optical coherence tomography-guided percutaneous coronary intervention are unclear. Therefore, in this study we sought to evaluate the impact of optical coherence tomography guidance on stent strut coverage following drug-eluting stent implantation. METHODS A total of 101 patients in 105 lesions were randomly assigned to receive percutaneou...
