    1. The Effect of Various Factors on Variability of Retinal Nerve Fiber Layer Thickness Measurements Using Optical Coherence Tomography

      The Effect of Various Factors on Variability of Retinal Nerve Fiber Layer Thickness Measurements Using Optical Coherence Tomography

      Purpose To evaluate the effects of various factors on the variability of retinal nerve fiber layer (RNFL) thickness measurements using the Stratus optical coherence tomography (OCT) in normal and glaucomatous eyes. MethodsFour hundred seventy-four subjects (103 normal eyes and 371 glaucomatous eyes) were scanned to determine the RNFL thickness measurements using the Stratus OCT. Measurements were obtained twice during the same day. The standard deviation (SD) was used to compare the variability in RNFL thickness measurements of the normal subjects to that of the glaucomatous patients. Multivariate regression analysis was used to evaluate which covariates were independent predictors of SD ...

    2. Changes in Central Corneal Thickness of Preserved Corneas Over Time Measured Using Anterior Segment Optical Coherence Tomography

      Purpose: To measure central corneal thickness (CCT) and investigate serial changes in CCT, using anterior segment optical coherence tomography (AS-OCT) on corneas in storage medium. Methods: Between July and August 2006, 10 human corneoscleral discs from 5 donors between 19 and 57 years of age were obtained. Corneoscleral rims were excised and were transferred to Optisol-GS (Bausch & Lomb, Irvine, CA). After preservation, AS-OCT (Visante OCT; Carl Zeiss Meditec) was performed on all corneoscleral discs to detect serial changes in CCT. The corneas were measured with AS-OCT at 0.5, 1, 2, 3, 4, 6, and 12 hours and then at 1, 2, 3, and 4 days after preservation ...

    3. The Effect of Soft Contact Lenses During the Measurement of Retinal Nerve Fiber Layer Thickness Using Optical Coherence Tomography

      Purpose: To investigate if the measurement of retinal nerve fiber layer (RNFL) thickness using optical coherence tomography (OCT) is affected by soft contact lens wear. Methods: This prospective, observational, cross-sectional clinical study looked at 66 eyes in 66 patients who usually wear soft contact lenses everyday and 36 eyes in 36 patients who did not wear contact lenses during the 6 months prior to the study. No patients had pre-existing retinal or optic nerve pathology or other media opacities that might influence the RNFL thickness. All eyes were scanned using the fast RNFL program of the Stratus OCT with and ...
