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...

PURPOSE Several studies have convincingly shown that in chicks, compensation for imposed focus involves immediate changes in choroid thickness. The molecular events associated with choroidal thickening and the regulation of the choroidal response are largely unknown. METHODS Form-deprivation myopia was induced in the right eyes of 2-day-old chicks by the application of translucent occluders f...

AIMS To assess the clinical and fluorescein angiographic features of choroidal folds seen in association with papilloedema. METHODS In a retrospective study, the clinical data from a database on patients with choroidal folds (1963-97), including fundus photography and fluorescein angiography, from 32 patients (64 eyes) with choroidal folds in association with papilloedema were reviewed. The c...

leiomyoma is a very rare intraocular tumor, which can occur in the iris, ciliary body and choroids. we report a case of choroidal leiomyoma in a 16-years old women whose left eye was enucleated because of clinical suspicion for melanoma. using conventional light microscopy tumor was interpreted as spindle cell tumor, most probably of neurogenic origin and after using immunohistochemical studies...

Purpose The role of β-adrenergic receptor (AR) signaling in neovascular ocular diseases has recently emerged. We have previously reported that intraperitoneal propranolol inhibits choroidal neovascularization (CNV) in vivo and β2-AR blockade reduces vascular endothelial growth factor (VEGF) expression in mouse retinal pigment epithelium and choroidal endothelial cells in culture. Here we tested...

OBJECTIVE To report integrative molecular analysis of choroidal melanoma fine-needle aspiration biopsy specimens to identify candidate tumor oncogenes. METHODS Thirty-one choroidal melanoma fine-needle aspiration biopsy specimens were analyzed using cytopathologic diagnosis of melanoma, fluorescence in situ hybridization for chromosome 3, cytogenetic characterization (GeneChip Human 250K NSPI...

A 27-year-old female presented with sudden visual loss of her right eye after receiving an autologous fat injection into the right nasolabial fold. Fundus examination of the right eye showed multiple whitish patchy lesions with macular edema. Fluorescein angiogram showed deterioration of choroidal circulation with patchy choroidal filling and arm-to-retina circulation time and retinal arteriove...

Purpose: To describe the spectral-domain optical coherence tomography features of chorioretinal folds of various etiology. Materials and methods: Cross-sectional observational case series of consecutive patients with chorioretinal folds. All patients underwent enhanced depth imaging optical coherence tomography over a two-month study period. Clinical variables and imaging features including sub...
