Visual features extracted from retinal fundus images have been increasingly used for glaucoma detection, as those images are generally easy to acquire. In recent years, genetic researchers have found that some single nucleic polymorphisms (SNPs) play important roles in the manifestation of glaucoma and also show superiority over fundus images for glaucoma detection. In this work, we propose to ...

PURPOSE To evaluate the peripapillary and perifoveal retinal perfusions of young healthy eyes with a tessellated fundus using optical coherence tomography (OCT) angiography. METHODS Thirty-five Chinese subjects with a tessellated fundus and 35 subjects without a tessellated fundus from a population-based cross-sectional study in Shanghai were included. All participants underwent OCT angiograp...

PURPOSE To compare the measurements of drusen area from manual segmentation of color fundus photographs with those generated by an automated algorithm designed to detect elevations of the retinal pigment epithelium (RPE) on spectral domain optical coherence tomography (SD-OCT) images. METHODS Fifty eyes with drusen secondary to nonexudative age-related macular degeneration were enrolled. All ...

In this issue of the Journal of Pediatric Ophthalmology & Strabismus, Ng, Lanigan, and O’Keefe present their findings regarding fundus fluorescein angiography in the management and screening of retinopathy of prematurity (ROP). Recently, there has been interest in photographic documentation of ROP in hospitals lacking sufficient ophthalmologic staff. Images created in the intensive care nursery...

Retinal fundus images are widely used in diagnosing and providing treatment for several eye diseases. Prior works using retinal fundus images detected the presence of exudation with the aid of publicly available dataset using extensive segmentation process. Though it was proved to be computationally efficient, it failed to create a diabetic retinopathy feature selection system for transparently...

The reproducibility of digital photogrammetry of optic nervehead photographs taken with the Zeiss fundus camera with Allen stereoseparator, the Donaldson fundus camera, and the Zeiss fundus camera with twin-prism separator were evaluated. Reproducibility of the various quantitative factors was significantly better when the two types of simultantic cups. Larger per cent errors were encountered w...

fundal gallbladder abnormalities result from broad spectrum of pathologic that most of them have no pathological significance and normally causes no symptoms. conversely, early incidental detection of malignant lesions is important because symptomatic lesions are often incurable. so use proper imaging to differentiate between them is important. although ultrasound has been the choice screen met...

Aim: To study Retinitis Pigmentosa as a cause of blindness in patients attending Regional Eye Hospital, Kurnool for blind certificate. Methods: A total 1020 all age groups to certificate during the period August 2020 2022 were included and examined which include visual acuity testing using Snellen chart, refraction, slit lamp biomicroscopy,intra ocular pressure measurement Goldmann Applanation ...

BACKGROUND The purpose of this study was to examine cone photoreceptors in the macula of patients with retinitis pigmentosa using an adaptive optics fundus camera and to investigate any correlations between cone photoreceptor density and findings on optical coherence tomography and fundus autofluorescence. METHODS We examined two patients with typical retinitis pigmentosa who underwent ophtha...
