iris recognition is one of the most reliable methods for identification. in general, itconsists of image acquisition, iris segmentation, feature extraction and matching. among them, iris segmentation has an important role on the performance of any iris recognition system. eyes nonlinear movement, occlusion, and specular reflection are main challenges for any iris segmentation method. in this pa...

CASE REPORT A 28-year-old man who received a blunt trauma in his left eye, presented with persistent ocular hypotony (intraocular pressure: 4 mmHg) as well as loss of visual acuity (0.4), optic disc edema and chorioretinal folds in the macula. The foveal thickness, measured by optic coherence tomography, was 326 microns. Using ultrasound biomicroscopy, a desinsertion of the nasal iris and a 360...

PURPOSE To report a case of aniridia in a pseudophakic patient following blunt trauma to the eye. CASE REPORT The traumatized eye had cataract surgery through a 3.0 mm clear corneal incision 6 years prior to the incident. While there have been previous cases of traumatic aniridia in pseudophakic eyes, previous reports have all occurred closer to the time of the cataract surgery. We believe th...

PURPOSE To determine the role of the murine interleukin-8 receptor homologue (mIL-8Rh, neutrophil chemokine CXC receptor 2) in leukocyte migration using intravital microscopy in a standardized model of eye inflammation, endotoxin-induced uveitis (EIU). METHODS Two hundred fifty nanograms of E. coli endotoxin was injected into the vitreous of knockout mIL-8Rh(-/-) (n = 7) mice or heterozygous ...

PURPOSE We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma. METHODS A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye....

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: ...

They compared our approach with their technique 2 and described some advantages with their technique. They opined that our technique did not take advantage of the intrascleral fixation of the IOL because a 25-gauge vitrectomy was performed before IOL fixation. With their technique, an anterior vitrectomy was performed using 25-gauge trocars for haptic externalization. We recommend performing a ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015213484 DESCRIPTION A 12-year-old girl presented with a history of repeated headaches (with no ocular symptoms) for 3 years. There was no history of ocular trauma or surgery. On ocular examination elsewhere, she was diagnosed as having intravitreal cysticercosis aft...

purpose: to report the development of cataract after corneal damage by dungle beetle prongs. case report: a 28 year-old man, resident of the village chah setareh, sabzevar, presented complaining of trauma to the right eye with the dangle beetle while motorcycling. slit lamp examination revealed six corneal perforations, hyphema (50% of anterior chamber) percent, iris sphincter rupture, and rupt...
