<h3>BACKGROUND</h3> This study evaluated the ability of laser scanning tomography to distinguish between normal and glaucomatous optic nerve heads, subjects with without field loss. <h3>METHODS</h3> 57 were classified into three diagnostic groups: elevated intraocular pressure, visual fields (n=10); neuropathy (n=30); repeatable abnormality (n=17). Three 10 degree image series acquired on each subject using Heidelberg retina tomograph (HRT). From 14 HRT stereometric variables, selected a...
<h3>AIMS</h3> (i) To evaluate the relation between retinal thickness and Z profile signal width of a scanning laser tomographer in selected patients exhibiting clinically manifest circumscribed macular thickening; (ii) to compare values group age similar normal subjects with those (iii) present methodology underlying derivation. <h3>METHODS</h3> Three following conditions were selected: widespread diabetic oedema; localised hole. The because they exhibited thickening. Patients underwent...
Purpose.: The purpose of this study was to determine the within-session variability and between-session repeatability spectral Fourier-domain optical coherence tomography (Doppler FD-OCT) Doppler retinal blood flow measurements in young elderly subjects. Methods.: FD-OCT measured using RTVue system. One eye each 20 healthy (24.7 ± 2.7 years) 16 (64.6 5.1 subjects randomly selected, pupil dilated. double circular scanning pattern employed. Six (i.e., separate measurement comprising an upper a...
<h3>AIM</h3> To assess the morphological change in retinal topography using a scanning laser tomographer following macular hole surgery. compare results of tomography with clinical evaluation and visual function assessment. <h3>METHODS</h3> The sample for this pilot study comprised four eyes exhibiting different stages formation preoperatively. Subjects were assessed preoperatively at 1 3 months postoperatively. Each assessment included acuity, letter contrast sensitivity, examination...
Automatic detection of retinal blood vessels is important to medical diagnoses and imaging. With the development imaging technologies, various modals images are available. Few currently published algorithms applied multimodal images. Besides, performance with pathologies expected be improved. The purpose this paper propose an automatic Ridge-Branch-Based (RBB) algorithm vessel centerlines for (color fundus photographs, fluorescein angiograms, autofluorescence images, SLO OCT example)....
This essay is based on a ten-minute video montage, exploring creative dialectical methods to address climate change. It inspired by Robert Smithson and Martin Buber. The site-specific performance, in Ireland has universal application. methodology uses Buber's "I Thou" it" promote ecological coexistence questioning traditional aesthetics. advocates for rewilding moving beyond the picturesque embrace beauty sublime nature. shows that loss of old burial ground (on sea edge) change must be...
This reports details the chronology of vision loss for an 18-year-old Caucasian male with Leber's optic neuropathy. Findings oculo-visual assessment auxiliary in-office tests visual neural function, results neurophysiological testing, and rehabilitative therapy low aids are presented. The clinical characteristics this devastating disorder reviewed.
Retinal thickness maps obtained using a scanning laser ophthalmoscope are useful in the diagnosis of macular edema and other diseases that cause changes retinal thickness. However, measurements adversely affected by presence blood vessels. This paper studies effect vessels have on computation The is estimated maximum-likelihood resolution with anatomical constraints. segmented local image features. Comparison without vessel removal made correlation coefficient I-divergence.
