Abstract
PURPOSE
To evaluate the usefulness of table parameters of Stratus optical coherence tomography (OCT) in order to detect localized retinal nerve fiber layer (RNFL) defects. METHODS: The present study included 86 glaucoma patients with only localized, wedge-shaped RNFL defects, as determined by red-free RNFL photographs. All subjects were tested fast RNFL scans, using of Stratus OCT. The sensitivity of the clock hour parameter and 11 table parameters of RNFL thickness average analysis were compared. RESULTS: The best parameters in the superior table parameter of the Stratus OCT were Smax, Savg, and Smax/Tavg (sensitivity = 36.7%, 36.7%, 36.7%, respectively). The best parameters in the inferior table parameter of the Stratus OCT were Iavg, Imax, and Imax/Smax (sensitivity = 63.8%, 59.4%, and 50.7%, respectively). However, all were significantly lower than the sensitivity of the clock hour parameter (superior RNFL defect: 60%; inferior RNFL defect: 84.1%). CONCLUSIONS: The usefulness of the table parameters of the Stratus OCT used to detect localized RNFL defects in glaucoma patients is considered low because of its low sensitivity.
