• retina and choroid
  • All data sets were segmented and vascular layers in the retina and choroid were identified. (arvojournals.org)
  • OCT almost centered within the 1060-nm water transmission window significantly profits from lower scattering and allows investigation of the retina and choroid at an unprecedented combination of penetration and high speed at high resolution and may provide superior clinical feasibility to commercial 800-nm devices. (arvojournals.org)
  • Fluorescein angiography (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 angiographic camera. (wikipedia.org)
  • sclera
  • Folds are best imaged with SD-OCT. The patterns of retinal and choroidal folds are the products of a complex interplay between the degree of papilledema and anterior deformation of the load-bearing structures (sclera and possibly the lamina cribrosa), both modulated by structural geometry and material properties of the optic nerve head. (arvojournals.org)
  • Iridectomy - Removal of the affected piece of the iris Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina) Iridocyclectomy - Removal of the iris plus the ciliary body muscle. (wikipedia.org)
  • degeneration
  • We also describe cell death mechanisms that have been proposed to underlie RPE degeneration in AMD and discuss the role of autophagy in the regulation of disease progression. (mdpi.com)
  • membranes
  • In PVR, RPE cells proliferate and migrate to the vitreous cavity along with other types of cells (e.g., glial cells, fibroblasts, macrophages) and form fibrocellular membranes on the retinal surface or in the vitreous. (arvojournals.org)
  • blood-retinal
  • 10 , 11 The surgical procedure releases inflammatory mediators, such as prostaglandins, leukotrienes, and cytokines, which leads to the breakdown of the blood-aqueous barrier and of the blood-retinal barrier. (arvojournals.org)
  • Breakdown of the blood-retinal barrier can alter the cytokine milieu in the subretinal space and in the vitreous 6 and trigger the activation of RPE cells. (arvojournals.org)
  • ciliary
  • Melanomas (choroidal, ciliary body and uveal) - In the early stages there may be no symptoms (the person does not know there is a tumor until an ophthalmologist or optometrist looks into the eye with an ophthalmoscope during a routine test). (wikipedia.org)
  • artery
  • The central retinal artery is the first, and one of the smaller branches of the OA and runs in the dura mater inferior to the optic nerve. (wikipedia.org)
  • patients
  • SD-OCT revealed morphologically intact choroid in STGD patients with ICGA-imaged dark atrophy. (arvojournals.org)
  • Morphological patterns of Paneth cells are a prognostic biomarker in Western Crohn's disease (CD) patients, and are associated with autophagy-associated ATG16L1 and NOD2 variants. (jci.org)
  • thickness
  • Central retinal thickness (CRT) was measured before surgery and at M1 and M3. (arvojournals.org)
  • 8 Increase in central retinal thickness (CRT) is detectable at postoperative early periods, after the first day 9 or the first week after uncomplicated phacoemulsification. (arvojournals.org)
  • birdshot
  • In contrast, white dots appear later in the disease stages of birdshot choroidopathy, serpiginous choroiditis, and APMPPE. (wikipedia.org)
  • fluorescein
  • To evaluate differences in fluorescein angiography (FA) and indocyanine green angiography (ICGA), findings between subjects affected by Stargardt disease (STGD) and atrophic AMD. (arvojournals.org)
  • Fluorescein angiography (FA) and indocyanine green angiography (ICGA) are important tools for diagnostic and pathogenetic evaluation of the two diseases. (arvojournals.org)
  • A series of black-and-white or digital photographs are taken of the retina before and after the fluorescein reaches the retinal circulation (approximately 10 seconds after injection). (wikipedia.org)
  • tissues
  • Vogt-Koyanagi-Harada disease ( VKH ), also known as Vogt-Koyanagi-Harada syndrome , uveomeningitis syndrome and uveomeningoencephalitic syndrome , is a multisystem disease of presumed autoimmune cause, that affects pigmented tissues, which have melanin . (wikipedia.org)
  • The early images allow for the recognition of autofluorescence of the retinal tissues. (wikipedia.org)
  • occur
  • The lesion may occur within the choroid, between Bruch's membrane and RPE, or between the RPE and photoreceptors. (wikipedia.org)
  • central
  • STGD is one of the most common inherited retinal dystrophies, while AMD is the most important cause of central visual acuity loss in western countries. (arvojournals.org)
  • Processes
  • They also suggest an important role of proinflammatory cytokines in overcoming local proliferative/wound-healing responses, thereby controlling the development of disease processes at the retina/RPE/choroid interface. (arvojournals.org)
  • ophthalmology
  • The findings of the study are elucidating optimized conditions for RP treatment A study done at the Department of Ophthalmology at Seoul National University College of Medicine, examined the effects of TUDCA and UDCA on laser-treated choroids of rat models. (wikipedia.org)
  • treatment
  • It is not approved by the Food and Drug Administration, in the U.S. while UDCA is approved in the United States for the treatment of primary biliary cirrhosis Ongoing research is finding TUDCA has diminishing apoptotic effects, helping with cardiac function, Huntington's disease, Parkinson's disease, and stroke. (wikipedia.org)
  • Genetic
  • Some suggest a genetic predisposition to the disease, while others postulate an abnormal immune response to a virus. (wikipedia.org)
  • area
  • A typical camera views 30 to 50° of retinal area, with a magnification of 2.5x, and allows some modification of this relationship through zoom or auxiliary lenses from 15°, which provides 5x magnification, to 140° with a wide angle lens, which minifies the image by half. (wikipedia.org)
  • Occlusion of a short or long PCA will produce a smaller choroidal infarct within the larger area supplied by the specific parent PCA. (wikipedia.org)
