OCT is a valuable diagnostic tool for evaluation of tissue architecture of the postequatorial fundus (inner retina, outer retina, retinal pigment epithelium (RPE), and choroid). In ocular oncology, OCT allows for diagnosis, treatment planning, and monitoring response.

To describe the vascular features of choroidal tumors using enhanced depth imaging (EDI), optical coherence tomography (OCT), and OCT-angiography. Methods In this prospective study, we evaluated 116 Caucasian patients with choroidal tumors (60 eyes with choroidal nevi, 40 with choroidal melanoma, 6 with choroidal hemangioma, 2 with optic disc ...

2017年2月17日 · A pilot study to image the vascular network of small melanocytic choroidal tumors with speckle noise-free 1050-nm swept source optical coherence tomography (OCT choroidal angiography).

2011年7月7日 · Imaging of choroidal nevus with EDI OCT enables precise measurement of tumor thickness with comparatively reduced thickness relative to ultrasonography. Using EDI OCT, 94% of choroidal nevi were found to have overlying choriocapillaris thinning. The author (s) have no proprietary or commercial interest in any materials discussed in this article.

f choroidal tumors imaged using enhanced depth. underwent clinical fundus photography, ultrasonography, and EDI SD-OCT. Qual-itative characteristics (tumor outline, reflectivity and/or shadowing of choroidal layers, and detection of inner sclera) and quantitative characteristics (measurement of.

2014年7月4日 · Spectral domain enhanced depth imaging optical coherence tomography shows characteristic tumor surface topography of dome-shaped for choroidal nevus, melanoma, and hemangioma, “lumpy bumpy” for metastasis, and “placid, rippled, or …

OCT may serve as a noninvasive adjunctive tool for the differential diagnosis of choroidal tumors. Choroidal melanomas usually demonstrate regular surfaces on OCT, while choroidal metastases usually have an irregular and lobulated surface. 1. Introduction. The diagnosis of a choroidal tumor is based mainly on clinical characteristics.

With more advanced technology, OCT now provides imaging deeper into the choroid using a technique called enhanced depth imaging. This allows characterization of the thickness and reflective quality of small (<3 mm thick) choroidal lesions …

4 天之前 · The choroid, a highly vascular layer behind the retina, is an extension of the central nervous system and has parallels with the renal cortex, with blood flow far exceeding that of the brain and kidney. Thus, there has been growing interest of choroidal blood flow reflecting physiological status of systemic disease. Optical coherence tomography (OCT) enables high …

2018年6月1日 · Optical coherence tomography angiography (OCTA) is a new, noninvasive imaging modality used to assess the vasculature in chorioretinal disease. The purpose of this study was to describe OCTA findings in several chorioretinal tumors, specifically melanocytic tumors. We correlate these findings with clinical risk factors (RFs) for growth.
