    1. Measurement of the Optic Disc Vertical Tilt Angle With Spectral-Domain Optical Coherence Tomography and Influencing Factors

      Measurement of the Optic Disc Vertical Tilt Angle With Spectral-Domain Optical Coherence Tomography and Influencing Factors

      Purpose To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors. Design Cross-sectional diagnostic study. Methods One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study. Subjects underwent a full eye examination, biometry, and spectral-domain optical coherence tomography (SDOCT). The vertical tilt angle was measured on high-resolution cross-sectional SDOCT images passing through the ON head and foveal centers using the inner edges of the Bruch membrane opening as the reference plane. The correlation between the vertical tilt angle with the ...

    2. Measurement of Optic Disc Size and Rim Area with Spectral-Domain OCT and Scanning Laser Ophthalmoscopy

      Measurement of Optic Disc Size and Rim Area with Spectral-Domain OCT and Scanning Laser Ophthalmoscopy

      Purpose: To compare optic disc and neuroretinal rim area measurements from spectral-domain optical coherence tomography (SD-OCT) to those from confocal scanning laser ophthalmoscopy. Methods: Seventy-one eyes from 43 normal subjects or suspected/definite glaucoma patients were prospectively enrolled. All subjects had biometry with the IOLMaster and disc/retinal nerve fiber layer (RNFL) imaging with Cirrus SD-OCT (Optic Disc Cube 200x200) and Heidelberg Retina Tomograph (HRT). Keratometry-corrected (K-corrected) HRT measurements and uncorrected Cirrus disc and rim areas and disc measurements corrected for eye magnification with Bennett's formula (AL-corrected) along with 30-degree sectoral rim areas, vertical cup-to-disc ratio (VCDR), and cup ...

    3. Effect of Macular Edema on Optical Coherence Tomography Signal Strength

      Effect of Macular Edema on Optical Coherence Tomography Signal Strength
      Purpose: The purpose of this study was to examine the effect of macular edema (ME) on Stratus optical coherence tomography (OCT) (Stratus OCT, Carl Zeiss Meditec, Dublin, CA) signal strength (SS). Methods: Part 1: Macular OCT was performed in 57 eyes with ME, at 2 different time points with different degrees of ME. The relationships between SS change and change in center point thickness and total macular volume in two scans were examined. Part 2: In 54 eyes with ME, Stratus OCT examinations with macular thickness mapping and retinal nerve fiber layer analysis protocols were performed. The paired values of ...
