One of the sign for diagnosing diabetic retinopathy is Intraretinal Microvascular Abnormalities (IRMA). IRMA is located in the superficial retina area that adjacent to the non-perfusion area resulting venous beading at least two quadrant in the fundus image. The difficulties in venous beading detection are the characteristics of the objects in retinal blood vessel images were varied. There are ...

A digital imaging technique is utilized in almost all the fields. Based on image processing concept image particle shape can be analyzed in detail. Nowadays, in eye clinics, imaging of the eye fundus with modern technology is in high demand because of its worth and expected lifetime. Eye fundus imaging is considered a noninvasive and painless route to screen and monitor the micro vascular disti...

AIMS/BACKGROUND The study aimed to determine the influence of increased intraocular light scatter on the contrast in scanning laser ophthalmoscope (SLO) images and to examine to what extent SLO images can visualise the fundus through media opacities due to cataract. METHODS Intraocular light scatter was estimated from measurements of letter contrast sensitivity before and after cataract surge...

BACKGROUND/PURPOSE Light-chain deposition disease (LCDD) is a rare condition characterised by deposition of monoclonal immunoglobulin light chains (LCs) in tissues, resulting in varying degrees of organ dysfunction. This study reports the characteristic clinical ocular findings seen in advanced LCDD upon development of ocular fundus changes. This is the first report to describe this entity in v...

OBJECTIVE To show true color scanning laser ophthalmoscope (SLO) images produced by simultaneously imaging the retina with red, green, and blue lasers. METHODS Low-power red, green, and blue lasers were combined using fiber optics. By rapidly pulsing the lasers, each point on the fundus is illuminated by the 3 colors in quick succession, with the total power level being similar to that from a...

PURPOSE To characterize longitudinal structural changes in early stages of late-onset retinal degeneration to investigate pathogenic mechanisms. METHODS Two affected siblings, both with a S163R missense mutation in the causative gene C1QTNF5, were followed for 8+ years. Color fundus photos, fundus autofluorescence images, near-infrared reflectance fundus images, and spectral domain optical co...

OBJECTIVES This study was designed to investigate the value of 3-D optical coherence tomography (3-D OCT) combined with fundus photochromy in the diagnosis of acute central serous chorioretinopathy (CSCR). SUBJECTS AND METHODS 3-D OCT and fundus photochromy were performed on 30 patients (36 eyes) with acute CSCR. Fluorescein angiography (FA) was also performed to confirm the diagnosis and to ...

PURPOSE To evaluate a spectral imaging technique to detect the area of internal limiting membrane (ILM) peeling after vitrectomy for idiopathic macular hole. MATERIALS AND METHODS In a prospective study, 15 eyes of 15 patients with idiopathic macular holes were tested. After vitrectomy with ILM peeling, retinal images were taken with color fundus photography, red-free fundus photography, and ...

OBJECTIVE Telemedicine reporting of diabetic retinopathy (DR) screening using ultra-widefield (UWF) fundus camera. MATERIALS AND METHODS Cross-sectional study of diabetic patients who visited the endocrinology department of a private multi-specialty hospital in United Arab Emirates between April 2015 and January 2017 who underwent UWF fundus imaging. Fundus pictures are then accessed at the R...

Digital fundus Image analysis plays a vital role in computer aided diagnosis of several disorders. Image acquired with fundus camera often have low grey level contrast and dynamic range .We present a new method for fundus image contrast enhancement using Discrete Wavelet Transform (DWT) and Singular Value Decomposition(SVD).The performance of this technique is better than conventional and state...
