Decreased cortical thickness that signifies gray matter pathology and its impact on cognitive performance is a research field with growing interest in relapsing–remitting multiple sclerosis (RRMS) and needs to be further elucidated. Using high-field 3.0 T MRI, three-dimensional T1-FSPGR (voxel size 1 × 1 × 1 mm) cortical thickness was measured in 82 regions(More)
The callosal transfer of information to the visual cortex following its unilateral deafferentation from its geniculate input was studied in both hemispheres. Deafferentation was performed in adult cats by sectioning the optic tract. Action potentials of single cortical cells and visual evoked potentials were recorded from area 17-18 boundary in acute and(More)
PURPOSE To quantify subjective visual metamorphopsia in newly diagnosed patients suffering from diabetic macular oedema (DME) and other macular abnormalities and to evaluate anti-VEGF treatment effect. METHODS Patients with DME, subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) or retinal venous occlusion(More)
PURPOSE Corneal thickness inevitably increases following Descemet's stripping automated endothelial keratoplasty (DSAEK), owing to the addition of a donor graft. The current study compares different devices in assessing post-DSAEK intraocular pressure (IOP). METHODS We compared IOP values measured by the Goldmann tonometry (GAT), iCare rebound tonometry(More)
BACKGROUND Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. OBJECTIVES To describe a case in which the application of black tea to an eye(More)
BACKGROUND AND OBJECTIVE This pilot study evaluated the clinical utility of the MacuFlow software in measuring metamorphopsia prior to and following surgery in patients with vitreoretinal diseases. PATIENTS AND METHODS Four patients with vitreoretinal disorders causing metamorphopsia were included in this pilot study. Visual acuity (VA), optical coherence(More)
