Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS.

A usually benign neoplasm that arises from the cuboidal epithelium of the choroid plexus and takes the form of an enlarged CHOROID PLEXUS, which may be associated with oversecretion of CSF. The tumor usually presents in the first decade of life with signs of increased intracranial pressure including HEADACHES; ATAXIA; DIPLOPIA; and alterations of mental status. In children it is most common in the lateral ventricles and in adults it tends to arise in the fourth ventricle. Malignant transformation to choroid plexus carcinomas may rarely occur.

Microvascular loops and networks as prognostic indicators in choroidal and ciliary body melanomas. (1/1300)

BACKGROUND: Malignant melanoma of the ciliary body and choroid of the eye is a tumor that disseminates frequently, and 50% of the diagnosed patients die within 10 years. We investigated the hypothesis that, by histopathologic analysis of the arrangement of microvessels (i.e., small blood vessels) in loops and networks, we might be able to differentiate better those patients with a favorable prognosis from those with a poor prognosis. METHODS: We conducted a population-based, retrospective cohort study of melanoma-specific and all-cause mortality for 167 consecutive patients who had an eye surgically removed because of malignant choroidal or ciliary body melanoma during the period from 1972 through 1981. Microvascular loops and networks were evaluated independently by two pathologists who were unaware of patient outcome. RESULTS: Microvascular patterns could be assessed in 134 (80%) of 167 melanoma specimens. The 10-year probability of melanoma-specific survival was worse if microvascular loops (0.45 versus 0.83; two-sided P<.0001) and networks (0.41 versus 0.72, two-sided P<.0001) were present. In multivariate Cox regression analysis of melanoma-specific survival, the hazard ratios were 1.66 (95% confidence interval [CI] = 1.19-2.30) for the presence of loops and networks as a combined three-category variable, 2.36 (95% CI = 1.37-4.05) for the presence of epithelioid cells, 1.11 (95% CI = 1.03-1.19) for the largest basal tumor diameter (evaluated as a continuous variable), and 2.14 (95% CI = 1.25-3.67) for ciliary body involvement. CONCLUSIONS: Patients with malignant uveal melanoma who have a favorable prognosis can be distinguished from those with a poor prognosis by histopathologic analysis of microvascular patterns in uveal melanoma tumor specimens.  (+info)

Increase in the advanced glycation end product pentosidine in Bruch's membrane with age. (2/1300)

PURPOSE: To determine whether there is an age-related increase of pentosidine in human Bruch's membranes and to localize pentosidine and carboxymethyllysine (CML), two well-characterized, advanced glycation end products (AGEs) in aged human Bruch's membranes and choroid in vivo. METHODS: Human Bruch's membrane samples were isolated from the retinal pigment epithelium (RPE) and choroid and subjected to reversed-phase high-performance liquid chromatography to determine pentosidine content. A polyclonal anti-pentosidine antibody and a monoclonal antibody specific for carboxymethyllysine were used to localize AGEs in 20-month-old nondiabetic, 82-year-old nondiabetic, and 82-year-old diabetic globes. RESULTS: Human Bruch's membranes (n = 20) showed a linear age-dependent increase in pentosidine that reached approximately 0.17 millimoles pentosidine per mole hydroxyproline in late life (r = 0.896; P < 0.001). Immunohistochemical evaluation showed evidence of pentosidine in Bruch's membrane, choroidal extracellular matrix, and vessel walls in the 82-year-old nondiabetic and diabetic globes. A similar staining pattern was found with the anti-CML antibody. Basal laminar deposits and drusen stained with both antibodies in the elderly nondiabetic eye. In contrast, neither antibody stained the 20-month-old tissue. CONCLUSIONS: We provide biochemical and immunohistochemical evidence for the formation of pentosidine and CML structures in human Bruch's membrane and choroid with age. These changes could promote aging of the RPE-Bruch's membrane-choroid complex.  (+info)

Idiopathic central serous chorioretinopathy. (3/1300)

Idiopathic central serous chorioretinopathy (ICSC) is usually seen in young males with Type A personality. Clinical evaluation of the macula with fundoscopy and biomicroscopy, coupled with fluorescein angiography establishes the diagnosis. Indocyanine green angiographic studies have reinformed that the basic pathology lies in choriocapillaries and retinal pigment epithelium. Most of the ICSC resolve completely in four months, and some of them could resolve early with direct photocoagulation of the leaking site. Oral steroids have no role, and could even cause an adverse reaction.  (+info)

Clinical characteristics of CHARGE syndrome. (4/1300)

CHARGE syndrome, first described by Pagon, was named for its six major clinical features. They are: coloboma of the eye, heart defects, atresia of the choanae, retarded growth and development including CNS anomalies, genital hypoplasia and/or urinary tract anomalies, and ear anomalies and/or hearing loss. We experienced three cases of CHARGE syndrome who displayed ocular coloboma, heart defects, retarded growth and development, and external ear anomalies, and we also review the previously reported literature concerning CHARGE syndrome.  (+info)

Effects of bicarbonate ion on chick retinal pigment epithelium: membrane potentials and light-evoked responses. (5/1300)

The purpose of this study was to determine how changes in [HCO3-] alter the electrical properties of the retinal pigment epithelium (RPE). Experiments were conducted on the isolated chick retina-RPE-choroid preparation. The chamber holding the preparation allowed independent perfusion of the retinal and the choroidal surfaces. The light-evoked trans-tissue potential (TTP), the trans-epithelial potential (TEP), the trans-retinal potentials, and the intracellularly-recorded apical and basal membrane potentials were studied. Increasing the [HCO3-]0 in the choroidal bath from 25 to 40 mEq/1 led to an increase in the TTP and TEP. The same change in the retinal bath decreased the TTP because of a biphasic change of the RPE membrane potentials. There was also an increase in the amplitudes of the TEP, the c-wave and the slow PIII. The light-evoked subretinal K+ decrease was greater which is consistent with an increase in the photoreceptor light response. These observations indicated that the decrease of TTP resulted from a basal membrane hyperpolarization followed by an apical membrane depolarization induced by an increase in retinal [HCO3-]0. The relationship of these potential changes to the human bicarbonate responses is discussed.  (+info)

Dendritic cells and macrophages in the uveal tract of the normal mouse eye. (6/1300)

BACKGROUND/AIMS: Dendritic cells (DC) and macrophages are components of the immune cell populations in the uveal tract whose density, distribution, turnover, and function may play a role in the maintenance of immunological homeostasis in the eye. Little is known of these cells in the mouse eye despite this being the predominant experimental model in many studies of ocular immune responses and immunoinflammatory mediated eye diseases. The aim of the present study was to obtain further immunophenotypic data on resident tissue macrophages and DC populations in the mouse uveal tract. METHODS: Pieces of iris, ciliary body, and choroid dissected from perfusion fixed BALB/c mice were incubated whole in a variety of anti-macrophage and DC monoclonal antibodies (mAbs). Labelled cells were visualised using either single or double immunoperoxidase techniques. RESULTS: Quantitative analysis and double immunolabelling revealed that 80% of F4/80(+) cells (a mAb that recognises both DC and macrophages) in the iris are macrophages (SER4(+)). The iris contained a network of Ia+ cells (412 (SD 130) cells/mm2) of which two thirds appear to be DC. A similar pattern was observed in the ciliary body and choroid. Only a few DC in the uveal tract were very weakly reactive for mAbs which recognise B7-1 (CD80), B7-2 (CD86), beta2 integrin (mAb N418), and multivesicular bodies associated with antigen presentation (mAb M342). CONCLUSIONS: The present study reveals that the mouse uveal tract, like the rat, contains rich networks of DC and resident tissue macrophages. The networks of resident tissue macrophages in the mouse uveal tract closely resemble similar networks in non-ocular tissues. The phenotype of uveal tract DC suggests they are in the "immature" phase of their life cycle, similar to Langerhans cells of the skin, thus implying their role in situ within the eye is antigen capture and not antigen presentation.  (+info)

Zinc deficiency and oxidative stress in the retina of pigmented rats. (7/1300)

PURPOSE: To determine the effect of moderate zinc deficiency on antioxidant defenses and measures of oxidative stress in the retina and retinal pigment epithelium (RPE) of Brown Norway Rats. METHODS: Twenty-four rats were housed individually and divided into three groups of 8 rats each. Group 1 was fed ad libitum a semipurified control diet formulated to contain 50 parts per million [ppm] total zinc; group 2 was fed ad libitum an identical diet but containing 5 ppm total zinc; and group 3 was pair-fed the control diet but restricted in amount to that consumed by group 2. Food intake was measured daily and the rats weighed weekly. After 6 weeks, the rats were killed and the following measurements were made: serum zinc, serum alkaline phosphatase, retinal zinc, RPE-choroid zinc, RPE-choroid catalase, liver metallothionein (MT), retinal MT, RPE-choroid MT, retinal catalase, and retinal thiobarbituric reactive substances (TBARS). RESULTS: The following showed statistically significant differences between groups 2 and 3, respectively: serum Zn (1216 micro/l versus 1555 microg/l, P < or = 0.01), serum alkaline phosphatase (3.75 U/mg versus 5.10 U/mg, P < or = 0.05), liver MT (4.3 microg/mg protein versus 16.7 microg/mg, P < or = 0.0001), RPE-choroid MT (1.3 microg/mg protein versus 2.2 microg/mg, P < or = 0.02), retinal MT (0.85 microg/mg protein versus 2.8 microg/mg, P < or = 0.05), and retinal TBARS (6.2 nM/mg protein versus 2.2 nM/mg, P < or = 0.05). CONCLUSIONS: The results show that retinal MT and RPE MT concentrations are very sensitive to intake of dietary zinc. The increase in retinal TBARS in group 2 indicates that moderate zinc deficiency increases oxidative stress to the retina. The results also suggest that MT is protective against lipid peroxidation of retinal membranes.  (+info)

Structural specializations of the eye in the vizcacha (Lagostomus maximus maximus). (8/1300)

Vizcachas (Lagostomus maximus maximus, Chinchillidae) are nocturnal rodents living in burrows in many regions of Argentina, Bolivia, and Chile. We have studied the eye of the vizcacha using several light and electron microscopic procedures, with the purpose of understanding the role of vision in the behavior of this species. Our observations demonstrated an avascular, rod-rich retina, with a specialized region spanning through most of the equator of the eye. In this central band, all neural retinal layers exhibited a high cell density, whereas the photoreceptor layer was characterized by the presence of very long rods. In addition, the central region was associated with a distinct pigmentation pattern, including scarce granulation of the pigment epithelium, low pigmentation of the choroid, and the selective attachment of suprachoroidal cells to the inner scleral surface. These central modifications probably form the structural basis of a reflecting tapetum. The eye of the vizcacha received both long and short ciliary vessels, and a specialized cilio-sclero-choroidal vascular network appeared at the equatorial region. Our findings suggest that the equatorial region of the eye of the vizcacha could be a highly sensitive light detector related to foraging behaviors during crepuscular or nocturnal hours.  (+info)

A total of 56 eyes had choroidal vascular hyperpermeability, of which 49 eyes (87.5%) had enhanced-depth imaging OCT images available. Mean subfoveal choroidal thickness was 389.5 ± 121.1 μm in these 49 eyes. Subfoveal choroidal thickness was less than 200 μm in four eyes (one eye with typical exudative AMD, three eyes with PCV), between 200 and 400 μm in 21 eyes (4 eyes with typical exudative AMD, 17 eyes with PCVs), and greater than 400 μm in 24 eyes (4 eyes with typical exudative AMD, 20 eyes with PCVs, Fig. 2A). Of the 168 eyes with punctate hyperfluorescent spots, enhanced-depth imaging OCT images were available in 154 eyes (91.7%). Mean subfoveal choroidal thickness was 318.6 ± 127.4 μm in these 154 eyes. Subfoveal choroidal thickness was less than 200 μm in 30 eyes (10 eyes with typical exudative AMD, 16 eyes with PCV, 3 eyes with RAP, 1 eye with myopic CNV), between 200 and 400 μm in 79 eyes (16 eyes with typical exudative AMD, 59 eyes with PCV, 1 eye with RAP, 3 eyes with ...
The impact of pregnancy on the choroid is still under investigation. The aim of this study is to compare choroidal thickness measurements of healthy pregnant women in the third trimester and healthy non-pregnant women using spectral-domain optical coherence tomography (OCT). This cross-sectional study included 122 eyes of 61 women, divided into two groups: 27 healthy pregnant women in the third trimester and 34 age-matched healthy non-pregnant women. Choroidal thickness was measured using Enhanced Depth Imaging OCT at ten different locations: at the fovea and every 500 µm from the fovea up to 2500 µm temporally and up to 2000 µm nasally. There were no significant differences in the ten measurements of choroidal thickness comparing both groups. Mean subfoveal choroidal thickness was 304.1 + 9.6 µm in the control group and 318.1 + 15.6 µm in the pregnant women group (p = 0.446). There was also no statistically significant association between gestational age and choroidal thickness measurements in the
Mean follow-up was 1.6 ± 0.76 years, without difference between the two study groups (p=0.6766). Choroid was significantly thicker in the bilateral GA group eyes compared to the fellow eye CNV group eyes at baseline (mean choroidal thickness: 170.5 ± 78.5 μm vs 129.1 ± 36.1 μm, p = 0.0371 ) and during follow-up (mean choroidal thickness: 173.2 ± 86.1 μm vs 123 ± 32.1 μm, p = 0.0340) . Mean choroidal thickness significantly decreased during follow-up only in the fellow eye CNV group (p=0.0276 in the fellow eye CNV group vs p= 0.4137 in the bilateral GA group). Mean GA area was not significantly different in the two groups neither at baseline nor at follow-up (p=0.4118 in B-FAF and p= 0.6806 in NIR-FAF at baseline, p= 0.5734 in B-FAF and p=0.8945 in NIR-FAF at follow-up) even if mean GA area significantly increased in both groups during follow-up. Mean retinal sensitivity significantly decreased during follow-up only in the bilateral GA group (p= 0.0405 in the bilateral GA group vs ...
Results The mean choroidal thickness at the fovea prior to smoking was 301.1±63.1 μm, which decreased to 284.2±56.7 μm at 1 h and 270.8±80.0 μm at 3 h following smoking (p=0.001). The mean choroidal thickness was significantly decreased following smoking at all five extrafoveal points. The difference in choroidal thickness was not statistically significant at 1 and 3 h of smoking at all six points. In the control group, the mean baseline choroidal thickness at the fovea was 270.6±57.9 μm, which was 272.5±52.4 μm at 1 h and 273.8±57.4 μm at 3 h (p=0.816).. ...

Changes in axial length and choroidal thickness after intraocular pressure reduction resulting from trabeculectomy Shinichi Usui,1,2 Yasushi Ikuno,2 Sato Uematsu,1 Yuko Morimoto,1 Yoshiaki Yasuno,3 Yasumasa Otori11National Hospital Organization, Osaka National Hospital, Osaka, Japan; 2Department of Ophthalmology, Osaka University Graduate School of Medicine, Suita, Japan; 3Computational Optics Group, University of Tsukuba, Tsukuba, JapanPurpose: To evaluate changes in axial length and choroidal thickness after trabeculectomy.Patients and methods: Fourteen patients under 80 years of age with glaucoma, were enrolled. The choroid was imaged using prototypical high-penetration optic coherence tomography (OCT) and the thickness was measured. Axial length, choroidal thickness, and intraocular pressure (IOP) were measured bilaterally at 3 pm 1 day before and 6 days after trabeculectomy. The choroidal thickness was measured at the fovea and four other locations (2 mm superior, temporal, inferior, and nasal to
Relevance of choroidal change in glaucoma has long been a focus of interest in glaucoma research. The interest has been boosted recently since the description of parapapillary choroidal microvascular dropout (MvD) using OCT Angiography (OCTA) in glaucomatous eyes. It is acknowledged that choroidal thickness varies according to IOP change. Particularly, several studies demonstrated choroidal thickening weeks or months after trabeculectomy. However, there has been paucity in the literature about longer term effect of IOP lowering on the choroidal thickness. Kojima et al. reported thickening of the macular and peripapillary choroidal thickness after one year after trabeculectomy. Interestingly, the thickening was mostly due to the increases in the interstitial areas, while the luminal area was comparable to the preoperative state.. An interesting issue regarding the role of choroid in glaucoma is that how the optic nerve head perfusion is related with choroid. While the choroid is responsible for ...

3D swept-source OCT detected FCE in 9 eyes (7.8 %). The 3D scanning protocol ‎allowed for detection of small extrafoveal excavations and the 3D segmentation method ‎coupled with en-face scans allowed for clear visualization of the morphology of the ‎excavations. In 5 eyes with FCE, unusual choroidal tissue was detected beneath the ‎FCE, bridging between the bottom of FCE and the outer choroidal boundary. In addition, ‎three of those five eyes showed a suprachoroidal space below the FCE, as if the outer ‎boundary of choroid is pulled inward by this bridging tissue. FCE was often seen within ‎the leakage point and choroidal hyperpermeability. Eyes with FCE were more myopic ‎‎(-4.42 ± 2.92 diopters), and the subfoveal choroidal thickness was significantly thinner ‎‎(301.3 ± 60.1 µm), as compared to control CSC eyes (P = .001 and .036 respectively ...
Results Of the 462 recruited participants, 273 had no diabetes (mean age was 60.1±6.8 years), 100 had diabetes but no DR (61.8±7.4 years) and 89 had DR (62.4±6.0 years). In multiple regression analysis, after accounting for relevant confounders, compared with those without diabetes, participants with diabetes had significantly thinner mean choroidal thickness (CT; mean difference (MD)=−25.19 µm, p=0.001), smaller choroidal volume (MD=−0.23 mm3, p=0.003), more inflection points (MD=1.78, p,0.001) and lesser choroidal vascular area within the foveal (MD=−0.024 mm2, p=0.001) and macular (MD=−0.095 mm2, p,0.001) regions. Among the diabetic group, subjects with DR had significantly thicker mean CT (MD=25.91 µm, p=0.001), greater choroidal volume (MD=0.24 mm3, p=0.009), lesser inflection points (MD=−0.478, p=0.045) and greater choroidal vascular area at foveal (MD=0.016 mm2, p=0.019) and macular (MD=0.057 mm2, p=0.016) regions, compared with those without DR. ...

Advances in the discovery of the causes of monogenic retinal disorders, combined with technologies for the delivery of DNA to the retina, offer enormous opportunities for the treatment of previously untreatable blinding diseases. However, for gene augmentation to be most effective, vectors that have the correct cell-type specificity are needed. While animal models are very useful, they often exhibit differences in retinal cell surface receptors compared to human retina. In this study, we evaluated the use of an ex vivo organotypic explant system to test the transduction efficiency and tropism of 7 different adeno-associated viral type 2 (AAV2) serotypes in human retina and retinal pigment epithelium-choroid: AAV2/1, AAV2/2, AAV2/4, AAV2/5, AAV2/6, AAV2/8, and AAV2/9, all driving expression of GFP under control of the cytomegalovirus promoter. After 7 days in culture, we found that AAV2/4 and AAV2/5 are particularly efficient at transducing photoreceptor cells and that AAV2/5 is highly specific ...

Choroidal pressure-flow curves were obtained before and 30 min after topical application of 0.1 ml of betaxolol (Betoptic, 0.5%, n = 10), timolol (Timoptic, 0.5%, n = 10) or saline (n = 8) by varying the MAP without controlling the IOP and by raising IOP while holding the ...
Polypoidal choroidal vasculopathy (PCV) is one of the disorders within the pachychoroid spectrum diseases. The presence of pachyvessels is one of the characteristics of pachychoroid disorders. However, the relationship between the presence of pachyvessels and the clinical characteristics of PCV eyes has not been determined. The purpose of this study was to determine the relationship between the presence of choroidal pachyvessels and the clinical characteristics of eyes with PCV. The medical records of patients who were diagnosed with PCV and were treatment-naïve were reviewed. Fluorescein and indocyanine green angiography, fundus photography, spectral domain optical coherence tomography (SD-OCT), and enhanced depth imaging OCT (EDI-OCT) were used to obtain images of the choroid. The presence of pathologically dilated outer choroidal vessels, pachyvessels, was determined by ICGA images. These pachyvessels were confirmed to correspond with the large choroidal vessels in the EDI OCT images. The PCV eyes
This study aimed to analyze the choroidal characteristics in eyes with polypoidal choroidal vasculopathy (PCV, affected eyes) and unaffected fellow eyes, a
Polypoidal choroidal vasculopathy (PCV) is a disease of the choroidal vasculature.  It is present in both men and woman of many ethnicities, characterized by serosanguineous detachments of the pigmented epithelium and exudative changes that can commonly lead to subretinal fibrosis. Evidence supports that symptomatic patients with PCV can have complete regression without severe vision loss with photodynamic therapy (PDT) and anti-VEGF treatment.  
PurposeRecent studies have found a choroidal thickening in amblyopic eyes and suggested that there might be a relationship between the choroid and amblyopia. The present study aimed to evaluate the effect of a six-month treatment of amblyopia on choroidal thickness in anisometropic hyperopic amblyopic children. ...
PURPOSE To compare the 12-month real-world visual and disease activity outcomes of eyes with polypoidal choroidal vasculopathy (PCV) treated with a combination of photodynamic therapy (PDT) and anti-vascular endothelial growth factor (VEGF) injections (combination group) versus those eyes treated with anti-VEGF monotherapy alone with rescue PDT being used as required (monotherapy group). DESIGN Database comparative observational study. PARTICIPANTS Eyes with PCV as graded in the Fight Retinal Blindness! database from Australia, New Zealand, Singapore, and Switzerland.

Macular edema is a common cause of visual loss at uveitic patients. The aim of our study was to investigate retinal and choroidal thickness at the macula in anterior (AU) and intermediate (IMU) uveitis and in healthy individuals using spectral domain optical coherence tomography (SD-OCT). Case-control study of 21 patients with AU and 23 patients with IMU and 34 age-matched healthy controls was performed with Spectralis SD-OCT (Heidelberg Engineering, Germany). High resolution SD-OCT scans and macular mapping were applied for automated measurement of retinal thickness. Standardized, masked manual measurement of the choroidal thickness was performed in the center of the ETDRS fields on enhanced depth imaging (EDI) scans. Evaluation of central retinal subfield thickness, 3 mm and 6 mm perifoveal rings was performed in the corresponding ETDRS zones in patient groups. The mean central retinal subfield thickness was significantly higher in IMU (368.65 ± 115.88 μm, p = 0.0003), but not significantly
Summary: The purpose of the study is to analyse the effectiveness of pedicled RPE (retinal pigment epithelium) - choroid graft autotranslocation in scarred neovascular age-related macular degeneration (AMD) treatment. Material and Methods. Pedicled RPE - choroid graft autotranslocation was performed on 8 patients with scarred wet AMD. Follow-up was from 6 to 30 months. Visual acuity, ophthalmoscopy, optical coherent tomography and indocian-green angiography were analysed. Results. The average visual acuity increased from 0.009±0.006 to 0.018±0.022 (p=0.15). Visual acuity increased in 50% of the patients. In 50% of patients visual acuity decreased, which was associated with proliferative vitreoretinopathy in post-op period with retinal detachment formation. No cases of choroidal neovascularization recurrence were detected. According to angiography data normal choroidal perfusion in the rotated RPE - choroid patch was revealed after 1 month during the follow-up examination. Conclusion. Pedicled ...

The present study looked at the CT in POAG subjects (cases) compared with normal healthy subjects (controls) using SD-OCT and SS-OCT at the peripapillary and subfoveal locations. In our study, the CT measured on SD-OCT in cases was found to be thicker compared with controls in both peripapillary and macular area, however this difference was not statistically significant. The lower confidence limit of mean difference at all the points was in negative values on SD-OCT and a few points in SS-OCT, implying that in few patients the CT was thin in cases compared with controls. Similarly, a meta-analysis by Zhang et al (evaluating 22 studies) compared CT in glaucoma and normal subjects using EDI mode SD-OCT and found no significant difference in CT in POAG and normal subjects.6 This observation on SD-OCT might be due to poor sclerochoroidal delineation.. On SS-OCT, we found thicker CT in cases compared with controls in peripapillary and macular area, but only PPCT was statistically significantly ...
Choroid is one of the structural layers, playing a significant role in physiology of the eye and lying between the sclera and the retina. The segmentation of this layer could guide ophthalmologists in diagnosing most of the eye pathologies such as choroidal tumors and polypoidal choroidal vasculopathy. High signal-to-noise ratio and high speed imaging in Spectral-Domain Optical Coherence Tomography (SD-OCT) make choroidal imaging feasible. Several variables such as pre-operative axial length (AXL), time of day and age affect thickness of the choroidal vascularization and should be considered for segmentation of this layer. These days most of the eye specialists manually segment the choroidal layer which is time-consuming, tiresome and dependent on human errors. To overcome these difficulties, some studies have introduced different automatic choroidal segmentation methods. In this paper, we have conducted a comprehensive review on existing recently published methods for automatic choroidal segmentation

The market presents significant growth opportunities for vendors. Companies are increasingly forming strategic alliances and engaging in M&A to increase their market share. As the development cost of ophthalmic drugs is high, small biotechnology firms are forming alliances with big pharmaceutical companies for product development.. Ask Sample PDF of Choroidal Neovascularization Market Report @ http://www.marketreportsworld.com/enquiry/request-sample/10278447 According to the Choroidal Neovascularization report, Better infrastructure in terms of healthcare facilities and sophisticated treatment options has led to a rise in the life expectancy rates, leading to a rise in the number of people over 60 years. The normal aging process results in reduced choroidal blood flow, which leads to ischemia. This, in turn, leads to increased expression of VEGF and development of excess blood vessels resulting in choroidal neovascularization and finally the loss of vision. With the increase in older ...

Habitual smoking is associated with an increased risk of coronary artery disease, cerebral and peripheral vascular disease, including ocular diseases like age-related macular degeneration or diabetic retinopathy. Data of a recent study performed in the investigators lab revealed abnormal choroidal blood flow regulation in chronic smokers as compared to age-matched non-smoking subjects during isometric exercise. However, no information is yet available about the regulation of retinal vascular tone in habitual smokers.. Thus, in the current study, the investigators set out to investigate whether the regulation of retinal vessels diameters is affected in habitual smokers. It has been shown in several reports that stimulation with diffuse luminance flicker, increases retinal arterial and venous diameters, indicating for the ability of the retina to adapt to changing metabolic demands. In the current study we use this effect as a tool to investigate whether the flicker induced vasodilatation is ...
The patient was a 15-year-old girl with an established diagnosis of Alagille syndrome (AS) since early life. Her medical history was significant for systemic manifestations of AS including liver transplantation and pulmonary artery balloon dilation. She had an unusual triangular facies characterized by a broad overhanging forehead, deep set, hyperteloric eyes and small pointed chin. Her bestcorrected visual acuity was 1.0 in both eyes. Slit-lamp examination was positive for posterior embryotoxon in both eyes. Funduscopy revealed diffuse choroidal hypopigmentation with increased visibility of the choroidal vessels and symmetric, well-circumscribed macular discoloration (Figure 1). A circumferential chorioretinal atrophy was also detected in the peripheral retina (Figure 1). Fundus autofluorescence (FAF) imaging clearly defined hypofluorescent areas in the peripapillary regions that extended along the macula and had a sleep mask appearance (Figure 2). Peripheral circumferential chorioretinal ...
Previous studies have shown that wild-type retinas implanted with subretinal devices undergo photoreceptor degeneration in the region immediately overlying the device.5,18 The death of photoreceptors was attributed to the blockage of choroidal blood flow to the outer retina due to the solid nature of the subretinal implant. The inclusion of perforations was hypothesized to increase the health of the retina overlying the device. Our results show that INL thickness on the stimulating side of the IPA in retinas with solid IPAs is the same as IPAs with 5-μm perforations (Fig. 4). This indicates that the INL is less sensitive to the blockage of choroidal blood flow than the photoreceptors. Furthermore, the retinas with solid IPAs do not form pseudo-rosettes or undergo glial fibrosis, compared with IPAs with perforations. While the mechanism of retinal pseudo-rosette formation is unclear, higher rates have been observed in several retinal pathologies including retinal detachment,27 retinal ...

Choroidal neovascular are the new blood vessels that grow just below the retina and interrupt the vision. Choroid, which is responsible for oxygen and nutrients supply to the eye, is the area between the retina and the sclera, where the blood vessels grow and cause choroidal neovascularization (CNV).
The posterior choroidal artery is not in fact a single artery, although it is commonly referred to as such. The posterior choroidal arteries, often numbering up to 10 or 11 per hemisphere, are divided into medial posterior choroidal artery and la...

This is a 2-step process combining a light-activated drug called Visudyne (verteporfin) with light from a cold laser directed onto the abnormal area of retina. Once activated, the drug causes the abnormal vessels to close off. PDT does not cause direct damage to the surrounding retina. Therefore, it can be used to treat new vessels that are under the centre of the macula (fovea).. Several treatments are needed to keep the leaking blood vessels closed and stop the progression of wet MD. Close follow up and monitoring is needed to determine if further treatment is required.. Unlike anti-VEGF drugs with which the vision is usually maintained, patients undergoing PDT continue to lose vision in the first 6 months. Their vision then stabilises so that the eye does not progress to severe vision loss.. PDT is now rarely used to treat ordinary wet MD. It is sometimes used in conjunction an anti-VEGF drug to treat a type of MD called polypoidal choroidal vasculopathy (PCV) as some of these cases do not ...
Wetas complex existing approach already modeled the cornea and the corneal bulge of the eye, along with the scalera, and the Iris, - which are kind of obvious, but now we also matched the choroid, explained Williams. The choroid, also known as the choroid coat, is the vascular layer of the eye, containing connective tissues, that lies between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm. The choroid is inside surface of the eye, Williams explains. If you were to cut a persons eye open, youd see that theres this black material on the inside of the eyeball. It is a sort of an inky black thin little film that sits inside your eye to keep your eye from seeing a lot of white reflection that might otherwise just bounce around on the white surface of the inside of your eye. While common wisdom in simple medical texts describes the choroid coat as black, Weta discovered something ...

In the current study, quantitative mapping of choroidal thickness and volume and qualitative analysis of choroidal vascular integrity showed loss of choroidal tissue including the choriocapillaris layer in the convalescent stage of VKH. Additionally, loss of the choriocapillaris and the thinning of the choroid in the sub-macula area correlated with increased duration of the disease, lower VA, and the presence of structural changes in the retina.. Normal sub-foveal choroidal thickness measured by SD-OCT ranges from 260 to 287 μm and varies by age, refractive error, and ethnicity [24-26]. Choroidal thickness varies based on the nature of posterior segment pathology as well. For instance, choroidal thickness increases in hyperopia [24], acute VKH [14, 15, 18], central serous chorioretinopathy [27, 28], and polypoid choroidal vasculopathy [29, 30]. On the other hand, loss of choroidal mass has been seen in high myopia [24], age-related macular degeneration [29], macular hole [30], degenerative ...

Conventional fluorescein angiography also was performed. Results. Laser- targeted angiography revealed CNV as an abnormal pattern of brightly fluorescent vessels. The flow pattern of the bolus and histology, performed in some cases, ...
TY - JOUR. T1 - Influence of the time of day on axial length and choroidal thickness changes to hyperopic and myopic defocus in human eyes. AU - Moderiano, Daniel. AU - Do, Michelle. AU - Hobbs, Sam. AU - Lam, Vy. AU - Sarin, Simran. AU - Alonso-Caneiro, David. AU - Chakraborty, Ranjay. PY - 2019/5. Y1 - 2019/5. N2 - Research in animal models have shown that exposing the eye to positive or negative spectacle lenses can lead to predictable changes in eye growth. Recent research indicates that brief periods (1-2 h) of monocular defocus results in small, but significant changes in axial length and choroidal thickness of human subjects. However, the effects of the time of day on these ocular changes with defocus are not known. In this study, we examined the effects of monocular myopic and hyperopic defocus on axial length and choroidal thickness when applied in the morning (change between 10 a.m. and 12 p.m.) vs the evening (change between 5 and 7 p.m.) in young adult human participants (mean age, ...
In this article the ability of ultrahigh resolution ophthalmic optical coherence tomography (OCT) to image small choroidal blood vessels below the highly reflective and absorbing retinal pigment epithelium is demonstrated for the first time. A new light source (λc=1050 nm, Δλ=165 nm, Pout=10 mW), based on a photonic crystal fiber pumped by a compact, self-starting Ti:Al2O3 laser has therefore been developed. Ex-vivo ultrahigh resolution OCT images of freshly excised pig retinas acquired with this light source demonstrate enhanced penetration into the choroid and better visualization of choroidal vessels as compared to tomograms acquired with a state-of-the art Ti:Al2O3 laser (Femtolasers Compact Pro, λc=780 nm, Δλ=160 nm, Pout=400 mW), normally used in clinical studies for in vivo ultrahigh resolution ophthalmic OCT imaging. These results were also compared with retinal tomograms acquired with a novel, spectrally broadened fiber laser (MenloSystems, λc=1350 nm, Δλ=470 nm, Pout=4 mW) ...
Choroidal neovascularization (CNV) is a key pathological feature of several of the leading causes of vision loss including neovascular age-related macular degeneration. Here we show that a calreticulin anti-angiogenic domain (CAD)-like peptide 27, CAD27, inhibited in vitro angiogenic activities, including tube formation and migration of endothelial cells, and suppressed vascular sprouting from rat aortic ring explants. In rat model of laser-induced CNV, we demonstrate that intravitreal injection of CAD27 significantly attenuated the formation of CNV lesions as measured via fundus fluorescein angiography and choroid flat-mounts (19.5% and 22.4% reductions at 10μg and 20μg of CAD27 injected, respectively). Similarly, the reduction of CNV lesions was observed in the groups of rats that had received topical applications of CAD27 (choroid flat-mounts: 17.9% and 32.5% reductions at 10μg/mL and 20μg/mL of CAD27 installed, respectively). Retinal function was unaffected, as measured using

BACKGROUND AND OBJECTIVE To determine whether magnesium sulphate could induce controlled hypotension, reduce choroidal blood flow, provide a dry operative field and could be compared with sodium nitroprusside in the recently raised issue of the use of hypotensive anaesthesia in eye surgery, i.e. for choroidal tumour surgery as the choroid is the most fragile and vascular structure in the eye. METHODS Forty adult patients undergoing choroidal melanoma resection and anaesthetized with 2.5 mg kg(-1) propofol, followed by a constant infusion of 120 microg kg(-1) min(-1), and remifentanil 1 microg kg(-1), followed by a continuous infusion of 0.25 microg kg(-1) min(-1), were randomly assigned to two groups to receive either magnesium sulphate or sodium nitroprusside. RESULTS Controlled hypotension was achieved at the target systolic pressure of 80 mmHg within 107 +/- 16 and 69 +/- 4.4 s for magnesium sulphate and sodium nitroprusside, respectively. Choroidal blood flow decreased by 24 +/- 0.3% and 22 +/

Choroidal neovascularization describes the growth of new blood vessels that originate from the choroid through a break in the Bruch membrane into the sub-retinal pigment epithelium (sub-RPE) or subretinal space. Choroidal neovascularization (CNV) is a major cause of visual loss.
In order to find abnormal blood vessels under the retina and/or to identify conditions that can cause retinal swelling and reduced vision, it is sometimes necessary to perform a test called angiography.. This test is performed by injecting a dye into the vein of the arm, then photographing the dye as it passes through the circulation in the back of the eye. Depending on the pattern of dye transmission and leakage, certain disease processes can be identified. Two different dyes are commonly used: fluorescein and indocyanine green. Special digital cameras joined to computers are used to maximize the effectiveness of this test.. Doctors choose fluorescein angiography to study diseases of the retinal and choroidal blood vessels within the eye. The results of this test enable the physician to diagnosis many abnormalities of the retina and choroid that could not be diagnosed accurately otherwise. The results of this study also serve as a guide to laser treatment for many diseases of the retina and ...
(R,R)ZX-5 is a NO regulatory compound, which could significantly increase choroidal blood flow in New Zealand rabbit. The aim of this paper is to investigate the molecular mechanism of (R,R)ZX-5 promoting NO production. Besides this, we also investigated the antiangiogenic activity of (R,R)ZX-5. Analysis of Western blot showed that (R,R)ZX-5 up-regulated the expression of Akt, p-Akt (Thr473), eNOS and p-eNOS (Ser1177), down-regulated the expression of Cyclin D1 in human retinal endothelial cells and escalated the intracellular free Ca2+ concentration. Additionally, (R,R)ZX-5 inhibited the growth of blood vessels in the chick chorioallantoic membrane model. It is concluded that (R,R)ZX-5 promotes choroidal blood flow through PI3K/Akt-eNOS and Akt-Ca2+-eNOS pathways. Additionally, (R,R)ZX-5 can inhibit angiogenesis.

Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.

AU - Sinha, Debasish. AU - Lutty, Gerard Anthony. PY - 2012/3. Y1 - 2012/3. N2 - VEGF 165b is an anti-angiogenic form of VEGF 165 produced by alternative splicing. The localization of pro-angiogenic VEGF 165 and anti-angiogenic VEGF 165b was investigated during development of the vasculatures in fetal human eyes from 7 to 21 weeks gestation (WG). The fetal vasculature of vitreous, which includes tunica vasculosa lentis (TVL), had moderate VEGF 165 immunoreactivity at 7WG and very little VEGF 165b. Both forms were elevated at 12WG. VEGF 165 then decreased around 17WG when the TVL regresses but VEGF 165b remained elevated. In choroid, VEGF 165 was present in forming choriocapillaris (CC) and retinal pigment epithelium (RPE) at 7WG while VEGF165b was present in CC and mesenchymal precursors within the choroidal ...
This test is similar to fluorescein angiography in that a dye is injected into the vein in the arm and we take photographs over time to help us diagnose problems in the back of the eye. The difference, however, is that the dye is used to study mainly the choroidal circulation, or the layer of blood vessels underneath the retina. ICG angiography is used less frequently than fluorescein angiography, but it can be especially useful in cases where blood obscures visualization of the retina. ICG angiography is also performed with a digital (computerized) system at Retina Care Specialists, allowing for immediate interpretation by the physician.. ...

In this paper, we proposed a method based on the Freeman chain code to segment and count rhesus choroid-retinal vascular endothelial cells (RF/6A) automatically for fluorescence microscopy images. The proposed method consists of four main steps. First, a threshold filter and morphological transform were applied to reduce the noise. Second, the boundary information was used to generate the Freeman chain codes. Third, the concave points were found based on the relationship between the difference of the chain code and the curvature. Finally, cells segmentation and counting were completed based on the characteristics of the number of the concave points, the area and shape of the cells. The proposed method was tested on 100 fluorescence microscopic cell images, and the average true positive rate (TPR) is 98.13% and the average false positive rate (FPR) is 4.47%, respectively. The preliminary results showed the feasibility and efficiency of the proposed method ...
