“…6,[17][18][19] Coronal image acquisition is optimal for visualizing the true dimensions of the ON and perioptic CSF relative to the surrounding sheath. 12 The most commonly reported macroscopic findings in MR images of patients diagnosed with papilledema are the following: 1) enlargement of the ONS, 5,6,8,9,20 2) flattening of the posterior sclera, [13][14][15] 3) protrusion of the optic papilla into the globe, 6,11 and 4) tortuosity of the ON.…”

“…5,6,8,9,[12][13][14][15] Of the many imaging techniques, MR imaging has been of particular interest because of its ability to provide gross visualization of the optic globe, ON, orbits, and optic tract. Additionally, MR imaging provides higher soft-tissue contrast and free section orientation capabilities compared with CT and appears to be more accurate in assessing the ON than sonography.…”

“…[13][14][15] Gibby et al 13 noted this finding on CT scans and considered it to be the mildest in the spec- trum of changes leading to the protrusion of the ON head into the globe. Atta and Byrne 14 noted flattening of the posterior sclera on sonography in some patients with choroidal folds and papilledema.…”

SUMMARY: Papilledema, defined as swelling of the optic disc, frequently occurs in the setting of increased ICP and in a variety of medical conditions, including pseudotumor cerebri, sinus thrombosis, intracerebral hemorrhage, frontal lobe neoplasms, and Chiari malformation. Noninvasive imaging of the ON is possible by using MR imaging, with a variety of findings occurring in the setting of papilledema, including flattening of the posterior sclera, protrusion of the optic disc, widening of the ONS, and tortuosity of the ON. Early recognition of papilledema and elevated ICP is of paramount importance for ensuring restoration of vision. Newer advanced MR imaging techniques such as fMRI and DTI may prove useful in the future to assess the potential effects of papilledema on retinal and visual pathway integrity.ABBREVIATIONS: ICP ϭ intracranial pressure; IIH ϭ idiopathic intracranial hypertension; ON ϭ optic nerve; ONS ϭoptic nerve sheath; SAS ϭ subarachnoid space

“…Measurement of RCT was also performed with the 20-MHz probe by positioning the measuring calipers on the internal retinal surface and in correspondence with the sclerochoroidal interface. An RCT of 1.5 mm was considered as maximum threshold for normality in the macular area, as stated in previous reports [12, 13]. …”

Background: In Behçet’s disease posterior segment involvement is very frequent (about 80%). Macular edema is the most commonly observed complication and is related to reduction of visual acuity. The purpose of the study was to evaluate choroidal involvement during posterior vasculitis due to Behçet’s disease. Methods: Thirty eyes (15 patients) presenting with posterior vasculitis due to Behçet’s disease were studied. All patients had been evaluated with optical coherence tomography (Stratus OCT, Zeiss) to evaluate the retinal thickness (RT) and with standardized 8-MHz A scan echography to determine the retinochoroidal thickness (RCT). Echographic evaluation with 10- and 20-MHz probes was performed in all cases. Results: In 7 eyes (23.3%), both RT and RCT were normal. In 5 eyes (16.6%), they were both increased. In the other 18 eyes (60%), the RCT was increased while the RT was normal, thus indicating a thickening of the choroid alone. No significant correlation was found between choroidal thickness and the presence of vitreal abnormalities. Neither increases in RT nor those in RCT were significantly related to visual acuity. No correlation was found between RT or RCT and pharmacological treatment. Conclusion: Choroidal inflammation could often play a primary eti- ological role during posterior vasculitis in Behçet’s disease. Echographic detection of choroidal thickening in patients with Behçet’s disease not presenting with retinal alterations or visual symptoms could represent a useful way to detect an early inflammation, in order to start a proper therapy and to influence the final visual prognosis.

“…(12) Ultrasound imaging is very helpful in determining the cause of choroidal folds, and findings can vary depending on the aetiology. The most common findings include increased subarachnoid space, flattened posterior pole, and increased thickness of the retina and choroid layer (4,5,13) . In optical coherence tomography (OCT), folds in the hyperreflective line formed by the inner portion of the choriocapillaris, Bruch's membrane, and RPE are easily identified.…”

RESUMODobras de coroide é considerado o achado fundoscópico mais prevalente nos casos de tumor orbitário. São ondulações no epitélio pigmentado da retina, membrana de Bruch, porção interna da coriocapilar e que, em alguns casos, podem acometer a retina neurossensorial, sendo então chamadas de dobras coriorretinianas. Diversas condições, oculares e sistêmicas, cursam com dobras de coroide e devem ser corretamente investigadas e, caso necessário, prontamente tratadas. Nesta revisão iremos abordar os aspectos gerais das dobras de coroide, enfatizando suas características nos seguintes exames de imagem: Retinografia, autofluorescência, angiofluoresceínografia e tomografia de coerência óptica.
