PURPOSE To report a distinct type of calcification in hydrophilic intraocular lenses in complicated, traumatized eyes with a history of intraocular gas use. DESIGN Observational case series. METHODS Three cases of hydrophilic intraocular lens (IOL) opacification confined to the pupillary area are reported from clinical practice in London, UK. Clinical(More)
Recognition of discrete planar contours under similarity transformations has received a lot of attention but little work has been reported on recognizing them under more general transformations. Planar object boundaries undergo projective or affine transformations across multiple views. We present two methods to recognize discrete curves in this paper. The(More)
PURPOSE To investigate the effect of 180° versus 360° primary selective laser trabeculoplasty (SLT) on tonographic outflow facility and intraocular pressure (IOP). DESIGN Prospective, single masked randomised clinical trial. PARTICIPANTS Patients with untreated primary open angle glaucoma or ocular hypertension both with IOP > 21-35 mmHg. METHODS 40(More)
We report the first case of iris vascular tuft (Cobb's tuft) causing recurrent spontaneous hyphema and raised intraocular pressure that underwent laser photocoagulation (LaP). For the first time, we report fluorescein angiogram guided LaP of the lesion and feeder vessels and 1 year angiographic follow up. We also review indications and outcomes of LaP of(More)
Polygon approximation is an important step in the recognition of planar shapes. Traditional polygonal approximation algorithms handle only images that are related by a similarity transformation. The transformation of a planar shape as the viewpoint changes with a perspective camera is a general projective one. In this paper, we present a novel method for(More)
Community detection in social networks is a well-studied problem. A community in social network is commonly defined as a group of people whose interactions within the group are more than outside the group. It is believed that people’s behavior can be linked to the behavior of their social neighborhood. While shared characteristics of communities have been(More)
Allo-anti-M often has an immunoglobulin G (IgG) component but is rarely clinically significant. We report a case of hemolytic disease of the fetus and newborn along with prolonged anemia in newborn twins that persisted for up to 70 days postbirth. The aim was to diagnose and successfully manage hemolytic disease of newborn (HDN) due to maternal(More)
Monitoring system calls made by an application is useful for debugging, for diagnostics as well as for security applications. Existing tools for monitoring system calls either suffer from a large runtime overhead, or require root permission to change the kernel of the operating system. We propose an approach that tackles both of these issues. We implemented(More)
