Longitudinal Stability of Optical Coherence Tomography Measures of Peripapillary Retinal Nerve Fiber Layer Thickness, Macular Thickness, and Macular Volume in Control and Glaucomatous Eyes of Children
Background/Aims: To document baseline and longitudinal values for peripapillary retinal nerve fiber layer (RNFL) thickness, macular thickness, and macular volume as measured by optical coherence tomography(OCT) in glaucomatous and control eyes of children, followed prospectively for a mean of 2.4 years (range 0.5-5.3 years). Methods: OCT measurements (Fast RNFL 3.4 Thickness, Fast RNFL Map, and Fast Macular Thickness Map protocols; StratusOCT, Carl-Zeiss-Meditech, Dublin,CA) were obtained at baseline and on follow-up in 27 control and 19 glaucoma participants at the Duke University Eye Center Pediatric Clinic. Longitudinal changes were compared between groups with a two-sample-t-test and multiple linear regression analysis of covariance model adjusting for age, race, and baseline refractive error. Results: Eyes with glaucoma exhibited reduced baseline macular thickness, macular volume, and RNFL thickness, and increased myopia, compared to control eyes (eg. macular volume 6.54 vs. 7.03 mm3, p=0.006; RNFL 3.4 thickness 87.8 vs. 110.6ÎŒm, p=0.02). All OCT parameters studied showed minimal change over time, and rates of change were similar between groups. Conclusion: Baseline differences and longitudinal stability of OCT parameters were seen in normal and clinically stable glaucomatous eyes of children. These findings support continued study of OCT as an easily performed clinical adjunct in evaluation and management of children with glaucoma.Master of Public Healt

Interobserver Agreement in Clinical Grading of Vitreous Haze Using Alternative Grading Scales
PURPOSE: To evaluate the reliability of clinical grading of vitreous haze using a new 9-step ordinal scale vs. the existing 6-step ordinal scale. DESIGN: Evaluation of Diagnostic Test (interobserver agreement study). PARTICIPANTS: 119 consecutive patients (204 uveitic eyes) presenting for uveitis subspecialty care on the study day at one of three large uveitis centers. METHODS: Five pairs of uveitis specialists clinically graded vitreous haze in the same eyes, one after the other using the same equipment, using the 6- and 9-step scales. MAIN OUTCOME MEASURES: Agreement in vitreous haze grade between each pair of specialists was evaluated by the Îș statistic (exact agreement and agreement within one or two grades). RESULTS: The scales correlated well (Spearmanâs Ï=0.84). Exact agreement was modest using both the 6-step and 9-step scales: average Îș=0.46 (range 0.28â0.81) and Îș=0.40 (range 0.15â0.63), respectively. Within-1-grade agreement was slightly more favorable for the scale with fewer steps, but values were excellent for both scales: Îș=0.75 (range 0.66â0.96) and Îș=0.62 (range 0.38â0.87), respectively. Within-2-grade agreement for the 9-step scale also was excellent [Îș=0.85 (range 0.79â0.92)]. Two-fold more cases were potentially clinical trial eligible based on the 9- than the 6-step scale (p<0.001). CONCLUSIONS: Both scales are sufficiently reproducible using clinical grading for clinical and research use with the appropriate threshold (a â„2 and â„3 step differences for the 6-step and 9-step scales respectively). The results suggest that more eyes are likely to meet eligibility criteria for trials using the 9-step scale. The 9-step scale appears to have higher reproducibility with Reading Center grading than clinical grading, suggesting Reading Center grading may be preferable for clinical trials
