While the primary method for evaluating diabetic retinopathy involves direct and indirect ophthalmoscopy, various imaging modalities are of significant utility in the screening, evaluation, diagnosis, and treatment of different presentations and manifestations of this disease. This manuscript is a review of the important imaging modalities that are used in diabetic retinopathy, including color fundus photography, fluorescein angiography, B-scan ultrasonography, and optical coherence tomography. The article will provide an overview of these different imaging techniques and how they can be most effectively used in current practice.

Fundus fluorescein and indocyanine green angiography : a

The human fundus is a complex structure that can be easily visualized and the world of ophthalmology is going through a golden era of new and exciting fundus imaging techniques; recent advances in technology have allowed a significant improvement in the imaging modalities clinicians have available to formulate a diagnostic and treatment plan for the patient, but there is constant on-going work to improve current technology and create new ideas in order to gather as much information as possible from the human fundus. In this article we shall summarize the imaging techniques available in the standard medical retina clinic i. Adaptive optics, autofluorescence, confocal scanning laser ophthalmoscope, fluorescein angiography, indocyanine green angiography, multispectral, ophthalmoscopy, optical coherence tomography, retinal imaging, retinal oximetry, retro-mode imaging, wide-angle. The invention of the ophthalmoscope by von Helmholtz in triggered a cascade of other innovations and data analysis tools that has led to an increasingly accurate assessment of patients with retinal disease. In the twenty-first century amongst other techniques, ophthalmologists have access to a vast array of equipment and technology to image the fundus including the slit-lamp, fundus cameras, fundus fluorescein angiography FFA , indocyanine green angiography ICG , fundus autofluorescence FAF , optical coherence tomography OCT.

Choroidal folds. Corresponding author. Choroidal folds is considered the most prevalent funduscopic finding in cases of orbital tumors. They are ripples in the retinal pigment epithelium, Bruch's membrane, the inner portion of the choriocapillaris and in some cases, may affect the neurosensory retina, and then called chorioretinal folds. Several ocular and systemic conditions are associated with the finding and must be properly investigated and, if necessary, promptly treated. In this review we discuss the general aspects of choroidal folds, emphasizing their characteristic features in the following ophthalmological imaging tests: Retinography, fundus autofluorescence, fluorescein angiography and optical coherence tomography. Choroidal folds are grooves in the retinal pigment epithelium RPE , Bruch's membrane, the inner portion of the choriocapillaris and, in some instances, the neurosensory retina, in which case they are called chorioretinal folds

It seems that you're in Germany. We have a dedicated site for Germany. Fernando Eds. Written by experts in the field of ophthalmology, this new text assists in understanding new imaging technology and the clinical information it can provide. It allows the reader to review numerous images of various pathologies and would be of interest to retina specialists and ophthalmologists. Retinal imaging has undergone dramatic changes in the last decade, characterized by constantly improving image resolution, most notably, as it applies to macular diseases, thanks to ever evolving optical coherence tomography. However, imaging retina outside of the vascular arcades has come a long way with advent of new cameras and lenses.

Imaging in Diabetic Retinopathy

Fluorescein angiography [1] FA , fluorescent angiography FAG , or fundus fluorescein angiography FFA is a technique for examining the circulation of the retina and choroid parts of the fundus using a fluorescent dye and a specialized camera. Sodium fluorescein is added into the systemic circulation, the retina is illuminated with blue light at a wavelength of nanometers , and an angiogram is obtained by photographing the fluorescent green light that is emitted by the dye. The fluorescein is administered intravenously in intravenous fluorescein angiography IVFA and orally in oral fluorescein angiography OFA. The test is a dye tracing method. The fluorescein dye also reappears in the patient urine, causing the urine to appear darker, and sometimes orange.

 - Скрестив на груди руки, он вышел из ее кабинета. Мидж горящими глазами смотрела ему вслед. - О нет, можешь, - прошептала. И, повернувшись к Большому Брату, нажатием клавиши вызвала видеоархив. Мидж это как-нибудь переживет, - сказал он себе, усаживаясь за свой стол и приступая к просмотру остальных отчетов.

Получалось, что ТРАНСТЕКСТ трудится над шифром больше пятнадцати часов. Она хорошо знала, что процессор перебирает тридцать миллионов паролей в секунду - сто миллиардов в час. Если ТРАНСТЕКСТ до сих пор не дал ответа, значит, пароль насчитывает не менее десяти миллиардов знаков.
