Retinal detachment is defined as the separation of the retina from the underlying tissue.…Retinal Detachment (Retina Detachment): Read more about Symptoms, Diagnosis, Treatment, Complications, Causes and Prognosis. Retinal folds are the finding most likely to be confused with choroidal folds but there are several distinguishing factors that can be used to differentiate between the two 1, 2, 4, 17. Retinal folds are much finer than their choroidal counterparts . They are not limited to the posterior pole but instead can be found anywhere along the retinal ... The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissues, and lying between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye, while in the outlying areas it narrows to 0.1 mm. The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms the uveal tract. The structure of the choroid is generally divided into four laye

When the membrane is thin and translucent, it is often referred to as 'cellophane maculopathy'. In these cases the membrane is seen on fundoscopy as an irregular light reflex or sheen over the macula. As the membrane thickens and contracts it creates retinal folds and is known as 'macular pucker'. Choroidal foLds Exudative RD Ring choroidal detachment Causes of Choroidal neovascular membrane with HAMMAR Causes of trabecular pigmentation with PIGMENT Use HAMMAR Histoplasmosis ARMD Multifocal Choroiditis Myopia Angiod Rupture of the choroid Use PIGMENT Pseudoexfoliation & Pigment dispersion syndrome Iritis Glaucoma (Post angle closure Sequels of choroidal detachment (five patients, 25%) and retinal folds (four patients, 20%) were the most frequent reasons for visual decrease, followed by epiretinal membrane (two patients, 10%). Retinal edema is rare in the elderly, particularly in those with a thin retinal nerve fiber layer. Very low IOP does not itself disturb me. In this case, however, the patient has choroidal folds that appear symptomatic, so I would close down the bleb. Aug 13, 2018 · If the retina is also involved i.e., grooves are noted in both the Bruch’s membrane and the retinal pigment epithelium (RPE), then the condition is known as Chorioretinal Folds A variety of causes have been attributed to Choroidal Folds which include tumor of the eye, chronic swelling of the optic disc, surgery to the eye, and inflammation of the sclera (part of the eye structure). Figure 4: Differentiating features of chorioretinal folds and elevations corresponding to specific choroidal vessels. (A) This 46 year-old patient with chorioretinal folds and oral topiramate use has a thick subfoveal choroid (461 μm) and infoldings in the choriocapillaris, RPE, and outer retina which do not correspond to specific choroidal vessels; (B) In contrast, this 84 year-old patient ...

Aug 29, 2017 · Ikuno, Y. & Tano, Y. Retinal and choroidal biometry in highly myopic eyes with spectral-domain optical coherence tomography. Invest Ophthalmol Vis Sci 50 , 3876–3880, doi: 10.1167/iovs.08-3325 ... In contrast to chorioretinal folds (Figure 1), FCEs appear to be the result of individual, intermediate-sized choroidal vessels located immediately adjacent to the underlying RPE. Chorioretinal folds appear to involve choroidal and retinal contour changes, which do not correspond to specific choroidal vessels and have a distinct appearance on ... Jan 26, 2016 · There were rare macular RPE changes and subtle choroidal folds consistent with increased choroidal thickness, as well as a superonasal peripapillary CNVM with associated exudation OD . EDI-OCT of the macula revealed thick choroid with subtle choroidal folds overlying dilated outer choroidal vessels OD .
We do not feel this entity represents true CRF, but is rather the consequence of a relatively thin choroid resulting in the RPE being draped over the more rigid underlying choroidal vessels. An epiretinal membrane is a thin sheet of fibrous tissue that develops on the surface of the macula and can cause problems with central vision. What is an epiretinal membrane? If you think of your eye as a camera, the retina is like the photographic film.
Bruch’s membrane is visible as a thin line, detached from the RPE, having remained horizontal. ... showing RPE layer with choroidal folds. ... Guide to Interpreting Spectral Domain OCT ... hypertension, choroidal folds, chorioretinal folds, peripapillary folds, retinal folds W rinkles and folds develop when a surface layer on a compliant substrate is exposed to a tensile, compressive, or shearing stress. They occur in a variety of structures and materials, across a wide range of scales in both inorganic materials and living tissues. Choroidal folds are parallel grooves or striae involving the inner choroid, the Bruch’s membrane and the retinal pigment epithelium (RPE), and sometimes the retina (chorioretinal folds) . Optical coherence tomography (OCT) provides cross-sectional images of the retina and choroid, making it useful for investigation of choroidal folds . Symptoms from choroidal folds can vary depending on their cause and the rapidity of their progression. hypertension, choroidal folds, chorioretinal folds, peripapillary folds, retinal folds W rinkles and folds develop when a surface layer on a compliant substrate is exposed to a tensile, compressive, or shearing stress.
