A prospective clinical study to assess the value of immunoscintigraphy with a monoclonal antibody (MoAb) against high molecular weight melanoma associated antigen (225.28S) was performed in 43 patients with choroidal melanoma; in six patients with a lesion suspected of being choroidal melanoma, and in seven patients with a benign lesion simulating a choroidal melanoma. The results of immunoscin...

The aims of this study was to observe the variation in subfoveal choroidal thickness (SFCT) in patients with highly myopic macular complicated by choroidal neovascularization (CNV) and to compare choroidal thickness in these eyes with highly myopic eyes without CNV, matched with the others group by ages, genders, eye axial length and diopter. 72 cases with 72 eyes, confirmed with high myopia in...

PURPOSE To demonstrate anatomic and physiologic changes in the human choroid following systemic sildenafil citrate (Viagra®) using enhanced depth imaging spectral domain-optical coherence tomography (EDI-OCT) and swept-scan high-frequency digital ultrasound. METHODS Seven healthy male subjects (mean age 32.7 years) were evaluated at baseline and 2 hr after ingesting 50 mg of sildenafil. Swept...

PURPOSE To investigate associations between outcome of anti-vascular endothelial growth factor (VEGF) therapy and choroidal morphology in eyes with myopic choroidal neovascularization (CNV). METHODS Fifty-two eyes of 46 patients with myopic CNV received a single intravitreal anti-VEGF injection, followed by as-needed injections. Baseline choroidal thickness was measured at the fovea and 1.5 a...

PURPOSE Little is known about the choroidal circulation in human eyes with ocular hypotony. Recently, indocyanine green angiography (IA) became a useful method for examining choroidal circulation. The present study using IA was designed to determine choroidal circulatory disturbances in patients with traumatic hypotony maculopathy. METHODS Indocyanine green angiography was performed on 3 cons...

There is recent evidence that the perfusion of the choroid changes during dark-light transitions. We set out to investigate this response in more detail and to elucidate possible mechanisms involved in this process. For this purpose, the effect of dark-light transitions on choroidal perfusion was studied in healthy subjects. Choroidal blood flow and ocular fundus pulsation amplitude were measur...

CONTEXT Cortisol has been suggested as a risk factor for choroidal thickening, which may lead to retinal changes. OBJECTIVE To compare choroidal thickness measurements using optical coherence tomography (OCT) in patients with endogenous active Cushing's syndrome (CS) and to evaluate the occurrence of retinal abnormalities in the same group of patients. DESIGN Cross-sectional study. SETTIN...

PURPOSE To evaluate choroidal thickness in healthy pediatric population by swept-source longer-wavelength optical coherence tomography (SS-OCT). METHODS This was a cross-sectional comparative, noninterventional study. The macular area of 83 eyes from 43 pediatric patients (<18 years) was studied with an SS-OCT prototype system. Macular choroidal thickness was manually determined at 750-μm int...

We report a case of choroidal metastasis simulating uveal effusion syndrome. This patient with uveal metastasis from lung carcinoma presented with decreased vision in the left eye. Fundoscopic examination revealed pigmentary clumping, multiple choroidal nodules and serous retinal detachment. Fluorescein angioraphy revealed a leopard spots pattern similar to uveal effusion syndrome. Ultrasound r...

PURPOSE To evaluate changes in choroidal thickness in and outside the macula as a result of hemodialysis (HD) in patients with end-stage renal disease. METHODS Patients with end-stage renal disease treated with maintenance HD in the Dialysis Unit of Sanggye Paik Hospital, Seoul, South Korea, were included in this study. The choroidal thickness was measured in and outside the macula before and...
