Measurement of subfoveal choroidal thickness after cataract surgery in enhanced depth imaging optical coherence tomography.
PURPOSE To compare subfoveal choroidal thickness (SFCT) before and after uneventful cataract surgery using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS A prospective study was conducted on 115 eyes of 95 patients who had phacoemulsification. Measurements of SFCT were performed preoperatively, 1 day (D1), 7 days (D7), 1 month (M1), and 3 months (M3) after surgery usin...
متن کاملTopographic variation and interocular symmetry of macular choroidal thickness using enhanced depth imaging optical coherence tomography.
PURPOSE To report and analyze factors influencing topographical and interocular variations in choroidal thickness (CT) in a healthy adult population. METHODS One hundred eyes of 50 healthy subjects underwent visual acuity and axial length measurements and optical coherence tomography (OCT) with enhanced depth imaging (EDI). CTs at the fovea and at 3 mm nasal, temporal, superior, and inferior ...
متن کاملEnhanced Depth Imaging Optical Coherence Tomography: A New Way Measuring Choroidal Thickness in Pregnant Women
The body changes markedly during pregnancy; each system behaves differently from a nonpregnant state. As the eyes are the only windows to see directly what is going on in the internal environment, more and more researches have been done to explain the association between ocular changes and the physiological and pathological changes during pregnancy. The choroid is one of the critical parts of t...
متن کاملChoroidal thickness in myopic and nonmyopic children assessed with enhanced depth imaging optical coherence tomography.
PURPOSE We examined choroidal thickness (ChT) and its topographic variation across the posterior pole in myopic and nonmyopic children. METHODS A total of 104 children aged 10 to 15 years (mean age, 13.1 ± 1.4 years) had ChT measured using enhanced depth imaging optical coherence tomography (OCT). Of these children 40 were myopic (mean spherical equivalent, -2.4 ± 1.5 diopters [D]) and 63 wer...
متن کاملChoroidal thickness measurement by enhanced depth imaging and swept-source optical coherence tomography in central serous chorioretinopathy
BACKGROUND We evaluated subfoveal choroidal thickness measured with two different forms of optical coherence tomography (OCT), enhanced-depth imaging (EDI) and swept-source (SS) OCT, in central serous chorioretinopathy (CSC). METHODS Fifty-six eyes of 48 patients diagnosed with acute or chronic CSC, were studied prospectively. Subfoveal choroidal thickness was measured as the distance between...
