PURPOSE This study was designed to examine choroidal thickness in patients with diabetes using spectral-domain optical coherence tomography. METHODS Forty-nine patients (49 eyes) with diabetes and 24 age-matched normal subjects underwent high-definition raster scanning using spectral-domain optical coherence tomography with frame enhancement software. Patients with diabetes were classified in...

Background/aims: It is well known that light skin pigmentation is a risk factor for cutaneous melanoma. The aim of this study was to investigate the analogous association between choroidal pigmentation and posterior uveal melanoma. Methods: Cross sectional study of 65 consecutive patients diagnosed with posterior uveal melanoma (melanoma group) and 218 consecutive patients referred for general ...

AIMS To determine the effects of dynamic exercise on the circulation and the luminal and stromal areas of the choroid in normal eyes. METHODS This was a prospective interventional study of 38 eyes of 38 normal subjects enrolled by invitation. The systolic and diastolic blood pressures, heart rate, intraocularpressure, mean ocular perfusion pressure (MOPP), choroidal blood velocity, and enhanc...

Background: The purpose of this study was to evaluate optical coherence tomography and histologic measurements of retinal and choroidal thicknesses in guinea pig eyes, and assess the relationships between those thicknesses with spherical equivalent and axial length. Methods: Twelve tri-colored guinea pigs, aged from 5 to 6 weeks, were collected. Spherical equivalent (SE) was measured with a str...

PURPOSE To estimate size overlap between large choroidal nevi and small choroidal melanomas by using plotted frequency distributions of tumor size. METHODS Frequency distributions of largest linear basal diameter (LBD) and thickness (TH) of choroidal nevi and melanomas were plotted from published data and cases in the senior author's practice. Relative frequencies of choroidal nevi and melano...

BACKGROUND The aim of this study was to evaluate the effect of uneventful phacoemulsification on the morphology and thickness of the macula, the submacular choroid, and the peripapillary choroid. METHODS In 14 eyes from 14 patients, retinal macular thickness, choroidal submacular thickness, and choroidal peripapillary thickness were measured preoperatively and at one week and one month after ...

Purpose: To report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (EDI-OCT) technique Case report: A 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. EDI-OCT obtained from the affected...

Optical coherence tomography angiography (OCT-A) is a recently established noninvasive technology for evaluation of the retinal and choroidal vasculature. The literature regarding the findings in choroidal nevi is scarce. We report the OCT-A findings associated with two different variants. Subject one had decreased vascular flow signal in the choroidal, choriocapillaris, deep retinal, and super...

PURPOSE We report here, the morphological characteristics of the retina and choroid in a patient with hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, who was not aware of her pregnancy before visiting our hospital. METHODS Case report. RESULTS The patient complained of visual disturbances in both eyes for a few days. Extensive serous retinal detachment and hyperreflective...

The indications, technique, and results of embolization of arteriovenous malformations with liquid adhesive agents delivered through the anterior choroidal artery are reported. Arteriovenous malformations of the temporal lobe were found in four patients with intracerebral bleeding and two with intractable epilepsy. In five of the six, the dominant arterial feeder was the anterior choroidal arte...
