We measured frequency-of-seeing curves for tiny (1.125 and 3.375 min arc) stimuli flashed briefly at absolute threshold to estimate the density of foveal cones in normals and in subjects with Stargardt's macular dystrophy. Foveal absolute thresholds for Stargardt's were elevated 1.5 log units over normal. Analysis using Poisson counting statistics indicated that the quantal absorption to stimul...

We compared several indices of foveal visual function between two groups of people aged 60 and older. One group was comprised of individuals who had good acuity in one eye, but had a history of exudative aging macular degeneration (AMD) in the other eye. We measured visual function in these individuals' good eyes only. The second group was a normative group; it was comprised of individuals who ...

OBJECTIVE To collect a normative database of macular thickness, retinal nerve fiber layer (RNFL) thicknesses, and optic nerve topography in the healthy eyes of children aged 3 to 17 years using optical coherence tomography (OCT) measurements. METHODS Scans were obtained for 286 healthy children (black, 114; white, 154; other, 18). Each child had a dilated eye examination, an axial length meas...

INTRODUCTION Macular oedema is the main cause of visual impairment following retinal vein occlusion. The purpose of this study was to evaluate the anatomical and functional outcome of pars plana vitrectomy and internal limited membrane (ILM) peeling for macular oedema secondary to retinal vein occlusion. CLINICAL PICTURE This pilot study is a prospective nonrandomised series of 11 eyes of 11 ...

OBJECTIVE To assess the relative stabilities of optical coherence tomography (OCT)-based retinal volume and central foveal thickness measurements in the setting of eccentric or inconsistent fixation. METHODS Ten healthy right eyes underwent multiple macular OCT centered at fixation. To model the effect of eccentric or inconsistent fixation, OCT was repeated with scan centers precisely shifted...

IN a previous paper (van Balen and Henkes, 1960) we indicated the possibility of recording the response of the occipital lobe to light-stimulation in man. The use of Dawson's superimposition method together with the mathematical integration method enabled us to record the responses in all normal subjects. The specific response of the visual cortex consists of four different components: a small ...

Background: Localized macular edema and retinal nerve fiber layer (RNFL) thinning have been reported shortly after laser in situ keratomileusis (LASIK) in adults. However, it is still unclear how LASIK affects the retina of children. This study aimed to investigate the macular retina and RNFL thickness in children with refractive amblyopia who underwent femtosecond laser-assisted LASIK (FS-LASI...

This report describes a case of angiographically documented foveal avascular zone (FAZ) enlargement after a single intravitreal injection of bevacizumab for macular edema secondary to central retinal vein occlusion (CRVO). A 71-year-old female was treated with an intravitreal bevacizumab injection for macular edema following CRVO. Despite successfully decreased edema one month after injection, ...

OBJECTIVE To investigate the safety and efficacy of intravitreal triamcinolone acetonide as treatment for macular edema associated with central retinal vein occlusion (CRVO). METHODS We reviewed the medical records of 13 consecutive patients (13 eyes) with macular edema associated with CRVO who were treated with an injection of intravitreal triamcinolone acetonide (4 mg) at the University of ...
