Background and Objective: Uterus of rat with polycystic ovary (PCO) may show pathological features. We provided pathological evidence for the rat uterus with NO-induced PCO.    Materials and Methods: Wistar rats (weighing 200-250 g) were kept diestrous to receive L-arginine (50 mg/kg) intraperitoneally (i.p.) for 9 days/once a day. Control group solely received saline (1 ml/kg, 9 days/once per ...

The aim of this study was to determine the prevalence of polycystic ovary morphology (PCO) among Nigerian women attending for pelvic ultrasound. This was a retrospective study of the ultrasound scan findings of all women who attended for pelvic ultrasound scan at a new teaching hospital in southern Nigeria from the commencement of ultrasound services on 1 March to 31 July 2010. The main indicat...

This paper demonstrates the wide variety of systems for the analysis of posterior capsular opacification (PCO). No single system has been proved to be a gold standard and it is difficult to comment on the advantages of one system over another with the limited current knowledge on the effects of PCO on vision. There are few studies that actually compare the different systems of analysis. Researc...

purpose : a review of posterior capsule opacification (pco) after cataract surgery and some affecting factors methods : a cross-sectional study was designed to study cataract patients who underwent cataract surgery between 2003 and 2006 in farabi eye hospital, tehran, iran. random sampling was done. those with a history of uveitis, intraocular surgery, and eye trauma were excluded from the stud...

Posterior Capsule Opacification (PCO) is the commonest complication of cataract surgery occurring in up to 50% of patients by 2 to 3 years after the operation [1]. This paper proposes a new approach for the assessment of PCO digital images. The approach deploys an unsupervised learning technique for clustering image pixels into different regions based on chromatic attributes. The innovation asp...

JANUARY 2008 I CATARACT & REFRACTIVE SURGERY TODAY I 23 T he success of the continuous curvilinear capsulorhexis at reducing complications and providing satisfactory refractive outcomes depends on its centration, location, and size. Studies have demonstrated that the capsulorhexis’ diameter should be small enough to overlap 360o of the IOL optic’s periphery to reduce the risk of posterior capsu...

BACKGROUND Peritoneal absorption of CO(2) during abdominal insufflation in laparoscopy may disrupt the acid-base equilibrium and alter the physiological response to stress. Current nonventilated rodent models of laparoscopy do not manage the CO(2) load of pneumoperitoneum, but ventilated surgical rodent models are invasive (tracheotomy) and may independently induce the inflammatory response. ...

PURPOSE To describe a new method of measuring posterior capsule opacification (PCO) and intraocular lens (IOL) rotation and report the validation of the method. SETTING Ophthalmology Department, St. Thomas' Hospital, and Medical Imaging, Department of Physics, King's College, London, United Kingdom. METHOD A new interactive software program, POCOman, was developed for the semiobjective asse...
