Purpose To compare the agreement between optical coherence tomography (OCT)-based choroidal vascularity markers measured by two previously reported image binarization techniques. Methods Spectral-domain OCT using enhanced-depth imaging was performed in 100 eyes from 52 normal subjects. Choroidal images were binarized to luminal area and stromal area using two different algorithms. Choroidal v...

PURPOSE To examine choroidal thickness and area in healthy eyes using spectral-domain optical coherence tomography (SD-OCT). DESIGN Retrospective, observational case series. METHODS Thirty-four eyes (34 subjects), with no retinal or choroidal disease, underwent high-definition raster scanning using SD-OCT with frame enhancement software. Choroidal thickness was measured from the posterior e...

The aim of the study was to investigate the relationship between choroidal blood flow and systemic and ocular variables in patients with healthy eyes.In this prospective cross-sectional study, we examined 241 eyes of 241 healthy Japanese subjects (92 males and 149 females; mean age, 37.8 ± 17.0 years). The mean blur rate, a measure of the relative blood flow of the choroid, was determined using...

Synopsis In optical coherence tomography angiography, the choroidal vascular flow rate in choroidal melanoma is significantly lower than that in choroidal nevus. Objective The objective of this study was to describe the choriocapillaris and retinal features imaged by optical coherence tomography angiography (OCTA) in eyes with choroidal nevus from small malignant choroidal melanoma. Methods...

BACKGROUND Enhanced-depth imaging optical coherence tomography (EDI-OCT) provides high-resolution imaging of the choroid. Herein, we report multimodal imaging, including EDI-OCT, of a case of sarcoid choroidal granulomas. FINDINGS A 63-year-old female with biopsy-supported sarcoidosis presented with unilateral multifocal choroidal granulomas. Enhanced-depth imaging optical coherence tomograph...

We report a patient with bilateral choroidal metastasis from disseminated cervical squamous cell carcinoma. A 52-year-old woman presented with progressive bilateral visual loss due to choroidal masses in both eyes. The fundus examination revealed posterior serous retinal detachment in both eyes associated with creamy choroidal lesions. A thorough systemic work-up revealed choroidal metastasis f...

Choroidal osteoma is a rare intraocular bony tumor that typically manifests as a yellow-white, well-demarcated mass with geographic pseudopodal margins.1-3 This benign tumor predominantly occurs in the peripapillary or papillomacular region, most often in young women.1,2 Occasionally, choroidal osteoma can simulate an amelanotic choroidal tumor such as melanoma, nevus, or metastasis.1,2 This tu...

Purpose To analyze the relationship between choroidal thickness and the distribution of choroidal blood vessels in eyes with nonexudative AMD. Methods Eyes with a diagnosis of nonexudative AMD were imaged using a prototype 100-kHz swept-source (SS) optical coherence tomography (OCT) instrument (Carl Zeiss Meditec, Dublin, CA, USA) with a central wavelength of 1050 nm. We used an OCT cube scan...

PURPOSE To report 2 cases of Vogt-Koyanagi-Harada disease accompanied by remarkable choroidal folds in the acute stage. The early indicator of recurrence in these 2 cases was the identification of choroidal folds by spectral-domain optical coherence tomography (SD-OCT). CASE REPORTS A 68-year-old woman (Case 1) presented with visual loss in both eyes. Funduscopic examination revealed optic di...

abstract in this presentation, a case of bilateral choroidal folds in patient with diabetic retinopathy was reported. by our knowledge, this case presentation is the first report of choroidal folds in diabetic retinopathy, which bilateral symmetric and horizontal folds arranged in macula. the thick choroid that is developed in diabetics may be a cause of these folds but the source of difference...
