    1. Choroidal thickness changes after dynamic exercise as measured by spectral-domain optical coherence tomography

      Choroidal thickness changes after dynamic exercise as measured by spectral-domain optical coherence tomography

      Purpose: To measure the choroidal thickness (CT) after dynamic exercise by using enhanced depth imaging optical coherence tomography (EDI-OCT). Materials and Methods: A total of 19 healthy participants performed 10 min of low-impact, moderate-intensity exercise (i.e., riding a bicycle ergometer) and were examined with EDI-OCT. Each participant was scanned before exercise and afterward at 5 min and 15 min. CT measurement was taken at the fovea and 1000 μ away from the fovea in the nasal, temporal, superior, and inferior regions. Retinal thickness, intraocular pressure, ocular perfusion pressure (OPP), heart rate, and mean blood pressure (mBP) were also measured. Results ...

      A Quantitative Evaluation of the Posterior Segment of the Eye Using Spectral-Domain Optical Coherence Tomography in Carotid Artery Stenosis: a Pilot Study

      BACKGROUND AND OBJECTIVE: To evaluate the posterior segment of the eye using spectral-domain optical coherence tomography (SD-OCT) in patients with internal carotid artery (ICA) stenosis. PATIENTS AND METHODS: Prospective study enrolling 25 patients with ICA stenosis (study group) and 25 age- and gender-matched healthy individuals (control group). Macular choroidal thickness (CT) was measured at the fovea; other CT measurements were taken 1,000 µm away from the fovea in the nasal, temporal, superior, and inferior regions by enhanced-depth imaging OCT (EDI-OCT). The thicknesses of the retinal nerve fiber layer (RNFL), macula, and ganglion cell complex (GCC) were measured with SD-OCT ...

      Subfoveal Choroidal Thickness in Patients with Chronic Heart Failure Analyzed by Spectral-Domain Optical Coherence Tomography

      Purpose : To evaluate the subfoveal choroidal thickness (SFCT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in eyes of chronic heart failure (CHF) patients. Methods : Fifty-six patients with CHF and 56 age- and gender-matched healthy individuals were enrolled. The SFCT was measured by EDI-OCT. The ejection fraction of left ventricle (EFLV), age, intraocular pressure (IOP), axial length (AL), systolic and diastolic blood pressure, and ocular perfusion pressure (OPP) were also measured. Results : Mean SFCT was 181.2 ± 80.23 μm in the study group and 283.6 ± 52.4 μm in the control group ( p  = 0.000). There was ...

    5. Evaluation of Subfoveal Choroidal Thickness in Pregnant Women Using Enhanced Depth Imaging Optical Coherence Tomography

      Evaluation of Subfoveal Choroidal Thickness in Pregnant Women Using Enhanced Depth Imaging Optical Coherence Tomography

      Purpose: To evaluate the subfoveal choroidal thickness (SFCT) measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in pregnant women. Methods: In this prospective and cross-sectional study, 100 pregnant women and 100 age-matched nonpregnant women were enrolled. The SFCT was measured by EDI-OCT. The refractive error, intraocular pressure (IOP), axial length (AL), central corneal thickness (CCT), systolic and diastolic blood pressure, and ocular perfusion pressure (OPP) were also measured. Pregnancy-related factors including gestational age, maternal weight gain, and fetal weight were noted. Results: Mean SFCT was 371.1 ± 61.8 µm in the study group and 337.2 ± 62.4 ...

    6. Subfoveal choroidal thickness measurements with enhanced depth imaging optical coherence tomography in patients with nanophthalmos

      Subfoveal choroidal thickness measurements with enhanced depth imaging optical coherence tomography in patients with nanophthalmos

      Purpose To compare subfoveal choroidal thickness (SFCT) between patients with nanophthalmos and age-matched controls. Methods This prospective, cross-sectional and comparative study included 31 eyes from 31 patients with nanophthalmos (study group) and 31 eyes from 31 healthy subjects (control group). SFCT and central macular thickness (CMT) were measured with spectral domain optical coherence tomography. All participants underwent a standardised ocular examination including best corrected visual acuity (BCVA), central corneal thickness (CCT), anterior chamber depth (ACD) and refractive error (RE) measurements. Results Mean SFCT in the nanophthalmic eyes and in the control eyes were 551.3±87 µm and 330.5 ...

    7. Choroidal Thickness Changes After A Single Administration of Coffee in Healthy Subjects

      Choroidal Thickness Changes After A Single Administration of Coffee in Healthy Subjects

      Purpose: To investigate the changes in the subfoveal choroidal thickness measured by enhanced depth imaging optical coherence tomography after a single administration of a cup of coffee in healthy subjects. Methods: In this prospective study, 62 healthy subjects (study group) who received a cup of 100 mL Turkish coffee (57 mg caffeine/100 mL) and 54 healthy subjects (control group) who received the same amount of water were enrolled. In the study group, the participants underwent enhanced depth imaging optical coherence tomography scanning at baseline, and at 5 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, 4 hours, and ...
