PURPOSE To report the clinical and paraclinical features of two patients with orange- colored choroidal metastases in whom the primary cancers have not previously been associated with such lesions. CASE REPORT Orange-colored choroidal lesions were detected on the fundus examination of one patient with metastatic small cell neuroendocrine tumor of the larynx and oropharynx, and in another subj...

AIM To report the evolution of a de novo choroidal melanoma. METHOD This is a case report of a 22-year-old white male patient who has been undergoing periodic examination for a choroidal 'freckle' since 10 years of age. RESULTS In 2007, a fundus photograph of the left eye showed a nondescript area of choroidal hyperpigmentation temporal to the fovea. Progressive growth was observed and, by ...

Purpose: Choroidal osteoma is a rare tumor which features intraocular bone formation. This tumor can be complicated by choroidal neovascularization which is a cause of impaired vision in this condition. We present a case of choroidal osteoma with choroidal neovascularization as a complication. Methods: Case report with clinical and angiographic correlation. Results: A 16 year old female present...

OBJECTIVE To analyze the morphologic features and vasculature of the choroid in healthy eyes using spectral-domain (SD) optical coherence tomography (OCT). DESIGN Cross-sectional retrospective review. PARTICIPANTS Forty-two healthy subjects (42 eyes) with no ocular disease who underwent high-definition scanning with Cirrus high-definition OCT (Carl Zeiss Meditec, Inc., Dublin, CA) at the Ne...

PURPOSE To study the prevalence and 3-dimensional (3-D) tomographic features of focal choroidal excavations in eyes with central serous chorioretinopathy (CSC) using swept-source optical coherence tomography (OCT). DESIGN Prospective, cross-sectional study. METHODS We examined 116 consecutive eyes with CSC with a prototype 3-D swept-source OCT. 3-D images of the shape of the macular area, c...

Research over the past two decades has shown that the growth of young eyes is guided by vision. If near- or far-sightedness is artificially imposed by spectacle lenses, eyes of primates and chicks compensate by changing their rate of elongation, thereby growing back to the pre-lens optical condition. Little is known about what chemical signals might mediate between visual effects on the retina ...

PURPOSE To determine the frequency, patterns, associations, and biomechanical implications of retinal and choroidal folds in papilledema due to idiopathic intracranial hypertension (IIH). METHODS Retinal and choroidal folds were studied in patients enrolled in the IIH Treatment Trial using fundus photography (n = 165 study eyes) and spectral-domain optical coherence tomography (SD-OCT; n = 12...

Purpose To describe changes in the retina and choroidal flow by optical coherence tomography angiography (OCT-A) after a single dose of oral sildenafil. Method A case-control study. Patients in the study group received 50 mg of oral sildenafil. Patients in the control group received a sham pill. Retinal and choroidal images were obtained at baseline (before pill ingestion) and 1 hour after in...
