    1. Choroidal Thickness in Patients with Systemic Lupus Erythematosus Analyzed by Spectral-domain Optical Coherence Tomography

      Choroidal Thickness in Patients with Systemic Lupus Erythematosus Analyzed by Spectral-domain Optical Coherence Tomography

      Purpose : The aim of this study is to investigate the effect of systemic lupus erythematosus (SLE) on choroidal thickness (CT) in the subfoveal and perifoveal area as measured by enhanced depth imaging optical coherence tomography (EDI-OCT) in patients with SLE. Materials and methods : Fifty-eight patients with SLE (study group) and 58 healthy individuals (control group) were enrolled in the study. The subfoveal and perifoveal CT were measured by EDI-OCT. Results : The mean CT (μm) subfoveal, nasal, and temporal was 231.2 ± 57.6, 190.56 ± 30.64, and 222.65 ± 37.45 in the study group and 297.5 ± 45 ...

    2. 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 ...

    3. Evaluation of Retinal Nerve Fiber Layer Thickness in Acromegalic Patients Using Spectral-Domain Optical Coherence Tomography

      Evaluation of Retinal Nerve Fiber Layer Thickness in Acromegalic Patients Using Spectral-Domain Optical Coherence Tomography

      Purpose : To evaluate retinal nerve fiber layer (RNFL) thickness in acromegalic patients . Methods : A study group of 29 patients with acromegaly and a control group of 38 age-matched healthy individuals were enrolled in a cross-sectional study. The study group was further divided by tumor size into two subgroups, a macroadenoma group and a microadenoma group. Serum growth hormone (GH) and insulin-like growth factor-1 (IGF-I) levels were detected at the time of ophthalmological examination in the study group. In both the study and control group, the RNFL thickness in the four quadrants was measured by optical coherence tomography . The relationship between ...

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

      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. Assessment of the Anterior Chamber Angle in Patients with Nanophthalmos: An Anterior Segment Optical Coherence Tomography Study

      Assessment of the Anterior Chamber Angle in Patients with Nanophthalmos: An Anterior Segment Optical Coherence Tomography Study

      Purpose : To quantitatively assess the parameters of anterior chamber and angle dimensions by anterior segment optical coherence tomography (AS-OCT) in nanophthalmos. Methods : In this prospective, cross-sectional and comparative study, 34 eyes of 34 healthy individuals (control group) and 37 eyes of 37 patients with nanophthalmos (study group) were enrolled. A single experienced ophthalmologist imaged and measured the right eye with the Visante AS-OCT. The anterior chamber angle (ACA), angle opening distance (AOD) at 500 and 750 µm from the scleral spur, and trabecular–iris space area (TISA) at 500 and 750 µm at the nasal and temporal angles were measured ...

    6. Effects of posterior capsular opacification on the evaluation of retinal nerve fiber layer as measured by stratus optical coherence tomography

      Effects of posterior capsular opacification on the evaluation of retinal nerve fiber layer as measured by stratus optical coherence tomography

      Objective To evaluate the effects of posterior capsular opacification (PCO) and Nd:YAG laser capsulotomy on the evaluation of peripapillary retinal nerve fibre layer (RNFL) as measured by Stratus (Carl Zeiss Meditec, Dublin, CA) optical coherence tomography (OCT). Design Prospective interventional case series. Participants We studied 98 eyes of 89 patients experiencing PCO. Methods We performed a complete ophthalmologic examination and evaluation of RNFL as measured by Stratus OCT before and after Nd:YAG capsulotomy. The patients were classified on the basis of PCO score or signal strength (SS) obtained by prelaser OCT scans. Results The preoperative and postoperative peripapillary ...
