Abetalipoproteinemia is a rare autosoma1 recessive disorder characterized by the absence of apolipoprotein B.' It is caused by mutations of the microsomal triglyceridetransfer protein gene.' Ocular manifestations include retinitis pigmentosa-like changes, nystagmus, ophthalmoplegia, ptosis, cataracts, anisocoria, and angioid ~treaks.~ Helicoid peripapillary chorioretinal degeneration (HPCD) is ...

PURPOSE To investigate the value of multimodal confocal scanning laser ophthalmoscopy (cSLO) for phenotyping fundus lesions in patients with pseudoxanthoma elasticum (PXE) and to correlate these findings with morphologic alterations detected by spectral domain optical coherence tomography (SD-OCT). METHODS Imaging was performed with a combined SD-OCT-cSLO system (Spectralis HRA-OCT; Heidelber...

INTRODUCTION We describe the long-term effectiveness and tolerability of intravitreal vascular endothelial growth factor inhibitor ranibizumab in a patient with pseudoxanthoma elasticum with bilateral macular choroidal neovascularization secondary to angioid streaks. CASE PRESENTATION A 54-year-old Caucasian man with history of heart disease presented with visual loss in his right eye. An exa...

Breakdown of boundary layer streaks is studied experimentally and compared at zero and adverse (positive) streamwise pressure gradients on a wing under fully controlled experimental conditions. The varicose mode of streak breakdown is found to be a dominant mode in the case of the adverse pressure gradient. A strong influence of pressure gradient upon the development of the streak and the secon...

Patients with beta-thalassemia may present with an acquired diffuse elastic tissue defect due to degeneration of elastic tissue along with vaso-occlusive findings in the retinal microvasculature. Here we report the case of a patient with granular-like accumulation presenting as black sunburst lesions detected by optical coherence tomography (OCT). A 38-year-old man with beta-thalassemia interme...

A 21 year old male patient reported in 2003 with complaint of diminution of vision in left eye since 1 month. Best corrected visual acuity OD was 20/20 and 20/120 OS. Fundus evaluation revealed angioid streaks in both eyes with scarred Choroidal neovascularization (CNV) in left eye [Fig. 1]. He was followed up regularly at intervals of 3 months. In 2010, he noticed blurring of vision in the rig...

Most of commercial computed tomography (CT) system employs filtered back projection (FBP) based algorithm to reconstruct tomographic image. Although FBP originated from an analytical solution, it generates streak artifacts during practical implementation due to interpolation between projection lines. The presence of streak artifacts will result in misinterpretation of tomographic features espec...

A prospective fate map of the late gastrulation mouse primitive streak has been charted in 8.5 dpc mouse embryos developed in culture, using the lineage marker DiI to label groups of cells. As at earlier stages, the fate of cells in the 8.5 dpc primitive streak is regionalised such that successively more caudal regions of the streak give rise to more lateral mesoderm. While most labelled cells ...
