The superficial vascular plexus (SVP), the intermediate capillary plexus (ICP) and the deep capillary plexus (DCP) were analyzed separately as well as the deep vascular complex (DVC Paques M. The 3D retinal capillary circulation in pigs reveals a predominant serial organization. OCTA Measurements of the Deep Capillary Plexus. Deep capillary ischemia has some characteristic findings, and on spectral-domain optical coherence tomography, outcomes in conjunction with multimodal imaging are helpful for the diagnosis of the acute and the chronic stages of retinal deep capillary plexus ischemia. This case study reports that important retinal vascular changes in MacTel 2 occur in the deep capillary plexus of the retina, a layer poorly visualized by fluorescein angiography and, to a lesser extent, in the inner vascular plexus. Retinal vascular diseases such as diabetic retinopathy and vein occlusion affect all plexuses, but with different patterns of capillary loss and vascular malformations. Primary prevention. Ocular coherence tomography of the right eye revealed hyperreflectivity within layers of the retina and ocular coherence tomography angiography showed decreased vascular density and flow in the deep capillary plexus. Background: This study aimed to assess the influence of pubertal status on the results of optical coherence tomography angiography (OCTA) in children with type 1 diabetes (T1D).

To describe patterns of reperfusion in the superficial vascular plexus (SVP), deep capillary plexus (DCP) and choriocapillaris (CC) as detected on

HD patients had a significant reduction in macular thickness in both inner and outer superior sectors and the inferior outer sector. Conclusions: On optical coherence tomography angiography, areas of capillary nonperfusion of deep capillary plexus due to macular ischemia are associated with photoreceptor structural abnormalities and retinal sensitivity loss on microperimetry. Deep Retinal Capillary Plexus Decreasing Correlated With the Outer Retinal Layer Alteration and Visual Acuity Impairment in Pathological Myopia.

Features include; A hypereflective plaque between the outer plexiform and outer nuclear layers. However, one should always bear in mind the potential for artifacts in deep plexus visualisation (see below). OCT angiography (OCTA) is a new, non-invasive technique that images retinal vessels based on flow characteristics and has the ability to produce high resolution images of both the deep and superficial retinal capillary networks. Paracentral acute middle maculopathy (PAMM) is the result of an ischemic insult to the deep or intermediate capillary plexus, affecting the middle retinal layers [1, 2].It appears in cross-sectional optical coherence tomography (OCT) B-scans as a hyper-reflective band involving the inner nuclear layer (INL) [3,4,5].PAMM may occur in isolation or secondary to various retinal However, transient ischemia led to retinal atrophy after a few weeks. (a) An OCTA image of the superficial retinal capillary plexus (SRCP) in a 3.0 3.0 mm 2 area centered on the macula and (d) the cross-sectional segmentation of the SRCP. This highlights that the health status of deep capillary plexus and not only the choroid is important to the oxygen requirements of the photoreceptors in patients with diabetic macular ischemia. Multimodal imaging included OCT and OCTA.

Purpose: To assess microvascular blood flow of the deep retinal capillary plexus in eyes with paracentral acute middle maculopathy using optical (P = 0.02) and deep capillary plexus (P = 0.002). Alteration of inner retinal microvascular density and outer retinal sublayer thicknesses occurred in pathological myopia, especially decreased DRCP and thinner MEZ, which were significantly associated with worse BCVA. The custom-developed software was then used to quantify the vessel density for the superficial retinal capillary plexus (SRCP) and the deep retinal capillary plexus (DRCP). There were evidences suggesting that, compared with SVP, DCP is more related and vulnerable to Deep capillary plexus, outer retina and choriocapillaris are depicted free of lesions. Methods A 53-year-old woman was referred with a 1-week history of sudden onset of decreased vision in the right eye. However, early histological studies consistently revealed three distinct retinal capillary plexuses in the human macula, which were named the superficial vascular plexus (SVP), the intermediate capillary plexus (ICP), and the deep capillary plexus (DCP) 8, 9. Ophthalmology; Spectral domain OCT (SDOCT)-Outer retina is involved due to involvement of deep capillary plexus. 2017;58(13):57545763. Deep retinal capillary plexus decreasing correlated with the outer retinal layer alteration and visual acuity impairment in pathological myopia. Deep capillary plexus VD was 21.5% and DCP FAZ was 0.382 mm 2. The superficial and deep retinal capillary plexus in cases of fovea plana imaged by spectral-domain optical coherence tomography angiography. Purpose To quantitatively investigate the role of deep capillary plexus (DCP) in patients affected by type 3 macular neovascularization (MNV), compared to patients with reticular pseudodrusen (RPD) eyes and healthy controls, using optical coherence tomography angiography (OCTA). The deep capillary plexus, a single monoplanar capillary plexus located in the outer plexiform layer, has the lowest VD, a significant finding that might be used to evaluate retinal vascular diseases. Mean microaneurysm diameters with respect to capillary plexus of origin and retinal eccentricity are summarized in Table 1. Previous research suggested that the deep capillary plexus might be the primary site of venous outflow for the entire retinal microvasculature, leading the researchers of this current study to believe that the physiologic differences in structure and function between the [superficial] and [deep plexuses] might cause them to be affected differently in the menstrual Methods. An exploratory analysis of the demographic, clinical, OCTA (lesion number) and structural OCT (lesion size) was conducted. Methods: | a En face optical coherence tomography at superficial retina layer with segmentation lines of superficial capillary layer.b Optical coherence tomography angiography (OCTA) in superficial capillary plexus, whole vascular density (larger green circle), foveal vascular density (small green circle) and This highlights that the health status of deep capillary plexus and not only the choroid is important to the oxygen requirements of Invest Ophthalmol Vis Sci. The high-resolution optical coherence tomography showed the intermediate capillary plexus and deep capillary plexus at the outer borders of the inner nuclear layer. 4a, b) and more prominent in the deep retinal capillary plexus (Fig. The deep retina has no capillary plexus inside it, so it has the lowest oxygen saturation in the retina, and its tissue function relies on oxygen diffused mainly by the DCP and choroidal capillaries. The mean rate of vessel decrease in both the inferior and nasal sectors was also significantly faster in those with high myopia. PDF | Purpose: To assess retinal sensitivity and retinal morphologic changes of capillary nonperfused areas in diabetic macular ischemia. Download Citation | Quantitative analysis of retinal intermediate and deep capillary plexus in patients with retinal deep vascular complex ischemia | Aim: Methods The study was designed as an observational, cross-sectional clinical series of patients with CHM, which included 14 CHM eyes and 14 age-matched controls. Clinical examination and fluorescein angiography confirmed the diagnosis of a central retinal artery occlusion of the left eye. The FAZ area was also larger in RRD than in CSC ( p < 0.001). (c) In the deep capillary plexus (DCP), vascular flow density was lower in RRD than in CSC (p < 0.001). Jie Ye, Mengyi Wang, Meixiao Shen, Shenghai Huang, Anquan Xue, Jue Lin, Yuchen Fan, Jianhua Wang, Fan Lu, Yilei Shao. To report visualization of a case of retinal deep capillary plexus ischemia with antiphospholipid syndrome. Vascular density decreased with age in the three capillary plexuses. METHODS: The study included 14 eyes of 10 patients who were diagnosed as having diabetic retinopathy. To evaluate anatomical changes in superficial capillary (SCP) and deep capillary (DCP) retinal plexuses, as well as choriocapillaris (CC) ischemia in DM patients without diabetic retinopathy (DR) or with mild and moderate DR without diabetic macular edema (DME) using Optical coherence tomography angiography (OCTA) (DRI-Triton SS-OCT). Vascular outpouchings originate from deep capillary plexus, and there is an the absence of large vessel connections to superficial vessels. DESIGN: Prospective observational cross-sectional study. Disruption of ellipsoid zone/interdigitation zone In late stage, thinning of the outer nuclear layer may be seen Fundus photo- may not detect early lesions. Localized retinal capillary ischemia at the level of intermediate plexus is proposed as the mechanism underlying the development of these lesions. A retrospective review of the Previously available imaging modalities were unable to specifically target different layers of the retinal vasculature. The retinal capillary plexuses grid-based vessel density from the Optovue Angiovue OCTA (a) Superficial retinal vessel density map and (b) Deep retinal vessel density map from a normal subject, the (c and d) corresponding maps from one of the SLE patients.The dotted line is seen dividing the maps into nine quadrants with vessel density percentage calculated for The It has also helped to understand the middle capillary plexus abnormality in retinal vascular diseases . The vessel density of the deep parafoveal capillary plexus was significantly increased after PDT (p=0.027). Color fundus photography and 3 3-mm en face optical coherence tomography angiography segmented at the level of the deep retinal capillary plexus in 2 patients with retinal venous malformations. The vascular density in the superficial capillary plexus decreased from 49.15.02 to 42.74.89, the vascular density in the deep capillary plexus decreased from 47.65.81 to 45.36.14. To account for inter-eye correlation, generalized estimating equation (GEE) model was used. Conclusions and importance: Cocaine use has been associated with systemic and cardiac effects, as well as ocular sequelae. Nonperfusion grayish areas were more frequent in the deep capillary plexus (43 eyes, 84%) than in the superficial capillary plexus (30 eyes, 59%, P < .001). Results: Mean age was 31 years (range, 2255 years). Methods The study was designed as an observational, cross-sectional clinical series of patients with CHM, which included 14 CHM eyes and 14 age-matched controls. This case highlights the ability of OCTA to image and localize retinal disease by vascular distribution, previously difficult with conventional fluorescein angiography, and lends evidence to the belief that PAMM is caused by vascular injury to the intermediate and deep capillary plexus. 4c, d). Whole image vessel density of the deep capillary plexus in the psoriasis group was significantly lower in comparison with control subjects (47.5 6.2 vs 50.1 5.2, respectively, p = 0.03, t-test).Lower values of deep pVD in the psoriasis patients in comparison with the control group (51.6 4.9 vs 54.1 3.9, respectively, p The mean foveal avascular zone areas of the superficial capillary plexus and deep capillary plexus of the reticular pseudodrusen group were not different from those of the non- reticular pseudodrusen group (P = 0.734 and P = 0.594).The mean vascular densities of the superficial capillary plexus and deep capillary plexus of the reticular pseudodrusen group also This highlights that the health status of deep capillary plexus and not only the choroid is important to the oxygen requirements of the photoreceptors in patients with diabetic macular ischemia. The DCP functions as a vascular terminal, and the deep retina is therefore more sensitive to perfusion loss [28] [29] . PAMM is thought to be a reflection of intraretinal ischemia predominantly of the intermediate and deep retinal capillary plexuses located in the inner nuclear layer (INL). Background To test clinically relevant factors associated with quantitative artifact-free deep capillary plexus (DCP) metrics in patients with diabetes mellitus (DM). Reduced vessel density in deep capillary plexus correlates Spectral-domain optical coherence tomography (OCT) of the left eye showed paracentral acute middle maculopathy (PAMM), and OCT angiography showed severe attenuation of the deep capillary plexus. The superficial capillary plexus (a) is automatically segmented using as inner boundary the Z ILM (internal limiting membrane layer) and as outer boundary the Z IPL (inner plexiform player).The deep capillary plexus (b) inner boundary is Z IPL, while the outer is Z OPL (outer plexiform layer). Ophthalmology; These findings were published in the Journal of Glaucoma. Volumetric retinal blood ow increased by 39.934.9% in arteries and by 29.816.8% in veins. Results Comparing vascular images acquired from OCTA and confocal microscopy, we found (1) a good representation of the larger caliber retinal vessels, (2) an underrepresentation of retinal microvessels smaller than 10 m and branch points in all four retinal vascular plexuses, particularly the intermediate capillary plexus, (3) reduced visibility Intravitreal AAV2.COMP-Ang1 Attenuates Deep Capillary Plexus Expansion in the Aged Diabetic Mouse Retina Lara S.

Methods In this prospective observational study, a total of seventy-eight eyes of 78 These vessels could be visualized with unprecedented detail in three dimensions. In conclusion, we showed a strong increase in the retinal microvascular density in response to light stim-ulation, with the most pronounced effect in the supercial capillary plexus. The SCP and DCP had 2 different organizations, but the plexus The SRCP extends from the internal limiting membrane to The superficial capillary plexus (SCP) and deep capillary plexus (DCP), ONH, FAZ parameters, the flow area of the outer retina, and choriocapillaris were evaluated using OCTA. To evaluate anatomical changes in superficial capillary (SCP) and deep capillary (DCP) retinal plexuses, as well as choriocapillaris (CC) ischemia in DM patients without diabetic retinopathy (DR) or with mild and moderate DR without diabetic macular edema (DME) using Optical coherence tomography angiography (OCTA) (DRI-Triton SS-OCT).

There are two deeper capillary networks above and below the inner nuclear layer (INL) referred to as the intermediate and deep capillary plexuses, or ICP and DCP, respectively, which are supplied by vertical anastomoses from the SVP 1,2. Previous research suggested that the deep capillary plexus might be the primary site of venous outflow for the entire retinal microvasculature, leading the researchers Deep capillary plexus vessel density may predict visual recovery following successful rhegmatogenous retinal detachment surgery, according to a Deep retinal capillary plexus - although smaller changes were detected when compared to superficial plexus in inflammatory conditions, OCT-A is able to detect patterns associated with cystoid macular edema. Purpose To identify the effects of prolonged type 2 diabetes (T2DM) on the retinal microvasculature of each retinal capillary plexus in patients without clinical diabetic retinopathy (DR). When data from all retina eccentricities were pooled, the frequency of microaneurysms in the deep plexus (52.4%) was not different to that of those in the superficial or intermediate plexus (P = 0.880). None. On optical coherence tomography angiography, areas of capillary nonperfusion of deep capillary plexus due to macular ischemia are associated with photoreceptor structural abnormalities and retinal sensitivity loss on microperimetry. The spectrum of superficial and deep capillary ischemia in retinal artery occlusion. Using OCTA we have been able to show progressive changes in the vascular pattern in the deep and superficial retinal B-scan pictures showing the automatic segmentation of the vascular plexuses. Arf et al.11 subsequently reported a second patient with the lupus anticoagulant and prior venous and arterial thrombotic events who developed ischemia of the retinal deep capillary plexus.
