From 43 Nepalese leprosy patients skin smear negative, and treated with dapsone (diamino diphenyl sulphone), and without any sign of active leprosy or iritis, specimens from iridectomy during cataract surgery were studied histopathologically. Of 49 iris specimens only six (12%) were found to be without any histopathological change. Atrophy of the iris stroma was seen in 63% and neovascularisati...

PURPOSE To evaluate the indications, postoperative visual efficacy, and complication rate after intraocular implantation of an iris-claw aphakic intraocular lens (IOL). SETTING Oxford Eye Hospital, Oxford, United Kingdom. DESIGN Case series. METHODS This chart review comprised eyes with no capsule support that had anterior iris-fixation IOL implantation for aphakia between 2001 and 2009. ...

Purpose To report optical coherence tomography angiography (OCTA) of iris microhemangiomatosis. Observations A 75-year-old asymptomatic Caucasian man was found to have bilateral pupillary vascular lesions during cataract evaluation. Visual acuity was counting fingers in the right eye (OD) and 20/40 in the left eye (OS) with normal intraocular pressures in both eyes (OU). In each eye there wer...

PURPOSE To demonstrate the role of intravitreal bevacizumab in regression of iris neovascularization, and intraocular pressure (IOP) control in neovascular glaucoma. METHODS A retrospective random case series study was performed. Twenty eyes of 20 patients who presented with neovascular glaucoma were treated with intravitreal bevacizumab 2.5 mg in 0.1 mL. Retinal photocoagulation was performe...

PURPOSE To evaluate probable complications of ArtificialIris implantation with iris fixated intraocular lens. METHOD Development of photophobia, glare, and psychological strain during face-to-face communication in a 23-year-old man with a widespread traumatic iris defect terminate to make a decision for performing implantation of an ArtificialIris (Humanoptics, Erlangen, Germany) under the re...

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...

Aim: To evaluate the effect of intracameral lidocaine anesthesia (ILA) and subconjunctival (SLA) administered during cataract surgery on development prevalence intraoperative floppy iris syndrome (IFIS). 
 Material Method: The study involved medical records 86 patients having no risk factors other than small pupil size for IFIS whom ILA and/or SLA were applied phacoemulsification surgery. ...

Background. To analyze the effects of factors other than the ocular trauma score parameters on visual outcomes in open globe injuries. Methods. Open globe injuries primarily repaired in our hospital were reviewed. The number of surgeries, performance of pars plana vitrectomy (PPV), lens status, affected tissues (corneal, scleral, or corneoscleral), intravitreal hemorrhage, intraocular foreign b...

BACKGROUND The pulsed electron avalanche knife (PEAK-fc) is a new pulsed electrosurgical device that allows for precise, "cold" and traction-free tissue dissection. AIM To evaluate the surgical applicability, safety and potential complications of PEAK-fc in complicated cataract surgery. METHODS The study included five children with congenital cataracts, two patients with advanced senile cat...

AIM The purpose of this study was to investigate intraoperative iris behavior during some phacoemulsification maneuvers in rabbits treated with tamsulosin or finasteride. MATERIAL AND METHOD An experimental study was conducted on 26 Metis male rabbits aged 1.5 - 2 years, body weight between 3.4 and 5.6 kg, divided into three groups: Group 1 - Control, 6 rabbits; Group 2 - tamsulosin, 10 rabbi...
