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 ...

N2 - This study evaluated the effects of the topical β-adrenergic antagonist betaxolol and the non-selective β-adrenergic antagonist timolol on the choroidal pressure-flow relationship. Pentobarbital-anesthetized rabbits were instrumented with hydraulic occluders on the aorta and inferior vena cava to control MAP an ear artery cannula to measure mean arterial pressure (MAP), and two vitreous cannulas to control and measure intraocular pressure (IOP). Choroidal blood flow was measured by laser Doppler flowmetry with the fiber- optic probe tip positioned over the posterior pole. 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

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 ...

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 ...
Researchers at the Queensland University of Technology (QUT) are overcoming a gap in the eye health market by turning deep learning tools to eye scans in a bid to better identify diseases like glaucoma.. In a paper recently published in scientific journal Nature, the researchers outlined how a number of artificial intelligence (AI) techniques were used to analyse Optical Coherence Tomography (OCT) scans to give optometrists and ophthalmologists more information about eye health.. OCT scans are commonly used to measure and monitor the thickness of tissue layers in the eye, indicating changes to health over time.. The studys lead author, Dr David Alonso-Caneiro, said that while standard OCT processing tools define and analyse retinal tissues layers well, "very few clinical OCT instruments have software that analyses choroidal tissue".. "The choroid is the area between the retina and the sclera, and it contains the major blood vessels that provide nutrients and oxygen to the eye.. "So we trained a ...
When blood vessels grow rapidly in the choroidal tissue under the retina, the damage to vision can be fast and severe. These blood vessels leak resulting in damage and scarring of the retina. Anti vascular edothlelial growth factors (Anti-VEGF) are substances used to inhibit the expansion of these blood vessels. Avastin has become the most common anti-VEGF treatment for wet macula degeneration, and it requires ongoing injections into the eye. Due to the anti-VEGF nature of Squalamine, it has been tried in the past to restrict the new blood supply to growing tumors. Now it looks like it may be used by eye doctors to help prevent the damage new blood vessel growth creates in macular degeneration. ...
Choroidal neovascularization information including symptoms, causes, diseases, symptoms, treatments, and other medical and health issues.
The suprachoroidal space is normally virtual because the choroid is in close apposition to the sclera. As fluid accumulates, this space becomes real, and the choroid is displaced from its normal position.
