As powerful image editing tools are widely used, the demand for identifying the authenticity of an image is much increased. Copy-move forgery is one of the tampering techniques which are frequently used. Most existing techniques to expose this forgery need to improve the robustness for common post-processing operations and fail to precisely locate the tampering region especially when there are ...

A large family with Wagner's vitreoretinal degeneration but none of the non-ocular features of Stickler's syndrome has been studied with gene probes for type II coliagen. Recombination has been observed, thus excluding type II collagen as the site of mutation in this family. This report supports other published evidence that the WagnerStickler syndrome is genetically heterogeneous. In 1938, Wag...

AIMS Analysis of highly myopic eyes (mean myopia -11 D) with post-LASIK vitreoretinal complications (breaks, retinal detachment) that also had pre-LASIK vitreoretinal pathology (lattice, breaks). METHODS Retrospective case series. RESULTS 67 eyes in 56 patients with pre-LASIK retinal examination developed post-LASIK vitreoretinal complications. 17 of the 67 eyes (25.4%) had pre-LASIK vitreo...

PURPOSE To assess whether hyaloid adhesion is more prevalent in patients with age-related macular degeneration (AMD) than in control patients and to evaluate whether it is more prevalent in exudative AMD than in non-exudative AMD. METHODS This was a cross-sectional, controlled analytical study. Patients from the Ophthalmology Department of the Public Service Hospital of the State of São Paulo...

PURPOSE To compare the state of the posterior vitreous in exudative age-related macular degeneration (AMD) with eyes with nonexudative AMD and controls. DESIGN Prospective, observational case series. METHODS B-scan ultrasonography and optical coherence tomography (OCT) were performed in 163 eyes from 82 subjects older than 55 years, 50 eyes with exudative AMD, 57 with nonexudative AMD, and ...

Purpose Eyes with age-related macular degeneration (AMD) often harbor pathological changes in the retinal periphery and perimacular region. These extramacular changes have not been well classified, but may be phenotypically and functionally relevant. The purpose of this study was to demonstrate a novel grid to systematically study peripheral retinal abnormalities in AMD using geometric distorti...

Purpose. To evaluate the ability of spectral-domain optical coherence tomography to detect subtle amounts of retinal fluid when the choroidal neovascularization is detected as inactive via time-domain optical coherence tomography and clinical examination in neovascular age-related macular degeneration (nAMD) patients. Methods. Forty-nine eyes of 49 patients with nAMD after ranibizumab treatment...

OBJECTIVES To describe the clinical phenotype of a novel autosomal recessively inherited vitreoretinal dystrophy in one generation of a family originating from eastern Switzerland. METHODS A clinical study including electroretinographic investigations followed by laboratory-based genetic and molecular analysis. Four affected and 3 unaffected members of the family were examined. Ten candidate ...

PURPOSE The aim of this study was to evaluate the relationship between oxidative stress and human vitreous degeneration, using the presence of an evident posterior vitreous detachment (PVD) as a clinical sign and thiobarbituric acid-reactive substances (TBARS) and nitrite as oxidative biomarkers. METHODS We collected 42 vitreous samples from patients undergoing pars plana vitrectomy for two g...
