Macular hole: Perceptual filling-in across central scotomas
The present study examined perceptual distortions of a vertical line before and after macular hole (MH) surgery in 25 eyes of 24 patients. Participants' perceptual reports of distortions were classified as solid, bent right/left, thinned at the center, or broken. The majority of patients (72%) reported symmetrical distortions of the line pre-operatively. After surgery, participants with larger ...
متن کاملFilling-in of retinal scotomas
In this study we examined the perception of one- and two-dimensional patterns across central retinal scotomas, caused by age-related macular degeneration. In contrast with previous studies of disrupted visual input that used the blind spot and artificial scotomas, the current study used large central scotomas caused by physical retinal damage. Such damage is associated with atrophy and long-ter...
متن کاملEffect of macular hole volume on postoperative central macular thickness.
PURPOSE To evaluate the association between macular hole volume (MHV) and postoperative central macular thickness (CMT) using spectral-domain optical coherence tomography (SD-OCT). METHODS Thirty-three eyes of 30 patients with a large full-thickness idiopathic macular hole with or without vitreomacular traction who underwent surgical intervention were included in this cross-sectional study. C...
متن کاملOptokinetic nystagmus in patients with central scotomas in age related macular degeneration.
BACKGROUND Reports on the impact of a loss in the central field of vision on optokinetic nystagmus (OKN) are varied. A study was therefore undertaken to reassess the role of the central retina in the generation of OKN in a large group of patients with age related macular degeneration. METHODS Four groups of 20 patients were examined: a control group without scotoma and three groups with absol...
متن کاملHole Filling in Images
This project relates to automated 3D model generation of Urban Environments. Ground based modeling involves a setup of two 2D laser scanners, and a digital camera mounted on top of a truck. As we drive the truck in a city, the laser scans capture depth information using the LIDAR time-of-flight principle. These laser scans are then subjected to accurate localization and 3D data processing algor...
