Senile Choroidal Vascular Patterns and Drusen
Archives of Ophthalmology, 1963The laminar structure of the eye has provided a unique opportunity to study such structures as retinal vessels, corneal and trabecular endothelium, lens epithelium, and retinal pigment epithelium in flat mounts. Depigmented choroid has also been studied in whole mounts, but to our knowledge, no study has been made heretofore of flat mounts which permit

Inflammatory Choroidal Vascular Membranes
2020Inflammatory choroidal neovascularization (CNV) is a sight threatening complication of noninfectious and infectious uveitic disorders. It is the third most common cause of CNV after age-related macular degeneration (AMD) and pathologic myopia. In this review, we provide an overview of inflammatory CNV including a review of the pathogenesis, the ...

Physiology of the choroidal vascular bed
International Ophthalmology, 1983The choroidal vascular bed has many interesting features such as relatively wide but flat capillaries, fenestrated capillary walls and an enormous blood flow. The high flow rate results in a high oxygen tension in the tissue and is also of importance in the temperature control of the eye.

[Choroidal vascular occlusion].
Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2011Systemic lupus erythematosus (SLE) is a chronic, relapsing and remitting autoimmune disease of unknown etiology. As in other rheumatic diseases sicca syndrome is often present. Additionally retinal vascular pathologies such as cotton wool spots and intraretinal hemorrhages are present in 7-8% of patients with SLE.

Vascular modifications within a choroidal osteoma
Documenta Ophthalmologica, 1993We report a case of choroidal osteoma followed-up for 7 years. During this lapse of time the choroidal osteoma showed slight enlargement, development of subretinal hemorrhage and modifications of intratumoral vascularization. Some large intratumoral vessels visible at first examination disappeared at follow-up, while other vessels not observed before ...

Exploring choroidal angioarchitecture in health and disease using choroidal vascularity index
Progress in Retinal and Eye Research, 2020The choroid is one of the most vascularized structures of the human body and plays an irreplaceable role in nourishing photoreceptors. As such, choroidal dysfunction is implicated in a multitude of ocular diseases. Studying the choroid can lead to a better understanding of disease pathogenesis, progression and discovery of novel management strategies ...

Choroidal vascular aneurysm with massive choroidal hemorrhage.
Annals of ophthalmology, 1992A rare case of a choroidal vascular aneurysm arising from the short posterior ciliary artery is reported in a 40-year-old woman. The aneurysm was detected by fluorescein angiography. It caused recurrent choroidal hemorrhage with blindness as the outcome. The diagnosis of aneurysm would have been missed without fluorescein angiography.

CHOROIDAL VASCULARITY INDEX AND CHOROIDAL THICKNESS IN EYES WITH RETICULAR PSEUDODRUSEN
Retina, 2019Purpose: To evaluate choroidal vascularity index (CVI), choroidal thickness, choroidal volume, and choroidal intensity in subjects with nonneovascular age-related macular degeneration (NNVAMD) with and without reticular pseudodrusen (RPD). Methods: We included 60 eyes of 35 subjects

Submacular choroidal vascular pattern
Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1974The submacular choroidal vascular pattern was investigated by experimental occlusion of either one of the temporal short posterior ciliary arteries (SPCAs) or 1, 2, 3 or all of the vortex veins in 87 rhesus monkey eyes and evaluation of their filling defects and anastomoses by fluorescein fundus angiography (FFA).

OCT angiography and evaluation of the choroid and choroidal vascular disorders
Progress in Retinal and Eye Research, 2018The recent introduction of optical coherence tomography angiography (OCTA) has remarkably expanded our knowledge of the choroid through in vivo investigation of the anatomical and pathological features of this important vascular layer. New insights elucidating the morphological features of the choroid, in both physiological and pathological conditions,
