Dark-without-pressure fundus lesions.

Coloration of fundus lesions in bilateral diffuse uveal melanocytic proliferation.

PURPOSE To report differences in the coloration of fundus lesions between Asian and Caucasian patients with bilateral diffuse uveal melanocytic proliferation (BDUMP). CASES This syndrome was detected in 2 Japanese patients, 69 and 73 years old, with lung cancer who visited our department complaining of visual disturbances. The coloration of the fundus lesions was investigated in these 2 patie...

Detection of Dark Lesions in Digital Fundus Images

Morphological Exudate Detection in Retinal Images using PCA-based Optic Disc Removal

Diabetic retinopathy lesion detection such as exudate in fundus image of retina can lead to early diagnosis of the disease. Retinal image includes dark areas such as main blood vessels and retinal tissue and also bright areas such as optic disk, optical fibers and lesions e.g. exudate. In this paper, a multistage algorithm for the detection of exudate in foreground is proposed. The algorithm se...

Electroretinogram evaluation of equine eyes with extensive 'bullet-hole' fundic lesions.

OBJECTIVE To evaluate the impact of extensive bullet-hole nontapetal fundic lesions in horses on retinal function as measured by full-field electroretinography (ERG). MATERIALS AND METHODS Full-field ERG was performed on two horses with numerous bullet-hole lesions in the nontapetal fundus of both eyes. The ERG was first recorded from the eye with the more extensive lesions in response to a l...

Fine structure in diabetic retinopathy lesions as observed by adaptive optics imaging. A qualitative study.

PURPOSE Diabetic retinopathy is diagnosed by fundus photography and optical coherence tomography (OCT) scanning. However, adaptive optics (AO) imaging can be expected to add new aspects to the knowledge of diabetic retinopathy because photographic resolution is improved by reducing the influence of optical aberrations on retinal imaging. METHODS Nineteen patients with diabetes mellitus were s...
