A 6-year girl of Indian ethnicity was referred for poor vision. Examination showed bilateral persistent pupillary membrane covering the central pupil. When pupil was dilated, iris strands were connecting the central 1.5 mm diameter circular membrane with the pupillary margins (Figure 1). Homatropine 2% eye drops, 12-hourly, and spectacle correction of astigmatism failed to improve acuities bett...

In this paper we present a novel hybrid CPU-GPU approach for rendering curvilinear grids. Visibility sorting is accomplished by parallel peeling cells off the grid, utilizing an active cell peeling front. In each step, we compute the ray-cell intersection coordinates on the GPU, perform accurate volume integration (CPU), and determine the set of active cells for the next iteration (GPU). The ap...

A set of highly connected proteins (or hubs) plays an important role for the integrity of the protein interaction network of Saccharomyces cerevisae by connecting the network's intrinsic modules. The importance of the hubs' central placement is further confirmed by their propensity to be lethal. However, although highly emphasized, little is known about the topological coherence among the hubs....

PURPOSE The evaluation of anatomic and visual outcomes in macular hole cases treated with internal limiting membrane (ILM) peeling, brilliant blue (BB), and 23-gauge pars plana vitrectomy (PPV). MATERIALS AND METHODS Fifty eyes of 48 patients who presented between July 2007 and December 2009 with the diagnosis of stage 2, 3, or 4 macular holes according to Gass Classification who had undergon...
