A 59-year-old woman was referred to our clinic for a glaucoma evaluation. The visual acuity and intraocular pressure were normal in both eyes. However, red-free fundus photography in the left eye showed a superotemporal wedge-shaped retinal nerve fiber layer defect, and visual field testing showed a corresponding partial arcuate scotoma. In an optical coherence tomography examination, the macul...

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...

Background:Pregnancy induced hypertension, is the commonest form of life-threatening complications pregnancy. Pregnancy described as only physiological state in which most parameters are abnormal. The anatomical, and biochemical adaptations that take place a woman during short span human pregnancy profound. Compared with normotensive gravidas, patients elevated blood pressure have significantly...

Purpose: To evaluate the frequency of Age Related Macular Degeneration (ARMD) in patients presenting to a teaching hospital Pakistan, and find most common factors associated with high ARMD. Study Design: Descriptive Cross-sectional study. Place Duration Study: Layton Rehmatullah Benevolent Trust Free Eye Hospital Township Lahore from 1st January 2019 30th June 2020. Methods: A total 720 ages mo...

AIM To evaluate prospectively in an experimental model of chronic high pressure glaucoma whether the concept of a mainly diffuse pattern of optic nerve damage holds true for high pressure glaucoma. METHODS The study comprised nine eyes of nine rhesus monkeys (Macaca mulatta) with a mean age of 17.7 (SD 3.1) years (range 13-23 years). Experimental glaucoma was produced by multiple applications...
