I I A new method to recover and display 3D fundus lobictkn ~ow"w*n shape, inner bottom shape of eyeball, from stereo fundus image pair is developed. For the fundus stereo images, a simple stereo technique does not work, because the fundus is observed through eye lens and a contact wide-angle enlarging lens. In this yf lvLq: method, utilizing the fact that fundus forms a part of sphere, we ident...

A prospective, hospital based, clinical study was conducted in hypertensive patients referred to the eye OPD, KMCTH, Sinamangal during a period of three months to find out the incidence of fundus changes. A total of 302 hypertensive patients were included in the study and their fundus changes were evaluated by direct ophthalmoscopy. The age of the patients ranged from 30-70 years and the durati...

The wavelet-domain Hidden Markov Tree Model can properly describe the dependence and correlation of fundus angiographic images' wavelet coefficients among scales. Based on the construction of the fundus angiographic images Hidden Markov Tree Models and Gaussian Mixture Models, this paper applied expectation-maximum algorithm to estimate the wavelet coefficients of original fundus angiographic i...

PURPOSE To analyze high-resolution color photographs of the mouse fundus. METHODS A contact fundus camera based on topical endoscopy fundus imaging (TEFI) was built. Fundus photographs of C57 and Balb/c mice obtained by TEFI were qualitatively analyzed. RESULTS High-resolution digital imaging of the fundus, including the ciliary body, was routinely obtained. The reflectance and contrast of ...

The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonoph...

To report a case of bilateral isolated foveal hypoplasia in which multimodal imaging was used to confirm the diagnosis. Fundus autofluorescence imaging, optical coherence tomography (OCT), and fundus fluorescein angiography were used to describe the typical findings of a patient with isolated foveal hypoplasia. Spectral domain OCT showed absence of foveal depression and persistent inner retinal...
