    1. Diagnostic capability of peripapillary retinal nerve fiber layer parameters in time-domain versus spectral-domain optical coherence tomography for assessing glaucoma in high myopia

      Diagnostic capability of peripapillary retinal nerve fiber layer parameters in time-domain versus spectral-domain optical coherence tomography for assessing glaucoma in high myopia

      AIM : To evaluate and compare the diagnostic capabilities of peripapillary retinal nerve fiber layer (p-RNFL) parameters of Spectralis optical coherence tomography (OCT) versus Stratus OCT to detect glaucoma in patients with high myopia. METHODS : This is a retrospective, cross-sectional study. Sixty highly myopic eyes of 60 patients were enrolled, with 30 eyes in the glaucoma group and 30 eyes in the control group. All eyes received peripapillary imaging of the optic disc using Stratus and Spectralis OCT. Areas under the receiver operating characteristic curve (AUROC) and the sensitivity at specificity of >80% and >95% for p-RNFL parameters obtained using the ...

    2. Macular Diagnostic Ability in OCT for Assessing Glaucoma in High Myopia

      Macular Diagnostic Ability in OCT for Assessing Glaucoma in High Myopia

      Purpose: To compare the diagnostic abilities of spectral-domain optical coherence tomography (SD-OCT; Spectralis OCT) and time-domain OCT (TD-OCT; Stratus OCT). Changes in macular parameters in highly myopic eyes of glaucoma patients and highly myopic eyes of glaucoma suspects were evaluated and compared. Methods: We collected data from 72 highly myopic eyes (spherical equivalent, <=-6.0D). Forty-one eyes had perimetric glaucoma and 31 eyes were suspected to have glaucoma (control group). All eyes underwent SD-OCT and TD-OCT imaging. Area under the receiver operating characteristic (AUROC) curve and sensitivity were examined on macular volume and thickness parameters at a fixed specificity and ...

    3. Macular parameters of Stratus optical coherence tomography for assessing glaucoma in high myopia

      Macular parameters of Stratus optical coherence tomography for assessing glaucoma in high myopia

      Background The aim was to assess the macular parameters of glaucoma in highly myopic subjects. Methods In a retrospective study, we enrolled 72 highly myopic eyes (spherical equivalent up to -6.00 D), of which 31 had early to moderate glaucoma and 41 formed a control group. The diagnosis of early to moderate glaucoma was based on glaucomatous visual-field defects with a mean deviation better than -12 dB. All patients underwent imaging with Stratus optical coherence tomography. We subsequently performed analysis for macular volume and thickness parameters between two groups. Results Using Stratus optical coherence tomography, we found significantly lower ...

    4. Single-Shot Dimension Measurements of the Mouse Eye Using SD-OCT

      Single-Shot Dimension Measurements of the Mouse Eye Using SD-OCT

      The authors demonstrate the feasibility and advantage of spectral-domain optical coherence tomography (SD-OCT) for single-shot ocular biometric measurement during the development of the mouse eye. A high-resolution SD-OCT system was built for single-shot imaging of the whole mouse eye in vivo. The axial resolution and imaging depth of the system are 4.5 µm (in tissue) and 5.2 mm, respectively. The system is capable of acquiring a cross-sectional OCT image consisting of 2,048 depth scans in 85 ms. The imaging capability of the SD-OCT system was validated by imaging the normal ocular growth and experimental myopia model using ...
