Intereye Spatial Relationship of Abnormal Neuroretinal Rim Locations in Glaucoma Patients from the Diagnostic Innovations in Glaucoma Study
2006
Purpose To determine the spatial relationship in neuroretinal rim parameter values between eyes in ocular hypertensives, glaucoma suspects, and glaucoma patients. Design Observational-cross-sectional study. Methods A total of 334 eyes of 167 patients were included. All patients underwent confocal scanning laser ophthalmoscopy imaging in both eyes. Intereye concordance ratio of abnormal rim sectors as classified by the Moorfield regression analysis (MRA) was calculated as the ratio of matching abnormal rim areas to the total number of abnormal rim areas. The amount of agreement was calculated for each sector separately. Results Of the right (left) eyes, 39 (39) eyes were classified “borderli…
Agreement among 3 optical imaging methods for the assessment of optic disc topography.
2005
Purpose To assess the agreement of disc topography measurements between the Heidelberg Retina Tomograph (HRT II), Retinal Thickness Analyzer (RTA), and Optical Coherence Tomograph (StratusOCT). Design Observational cross-sectional study. Participants Forty-two randomly chosen eyes of 42 subjects. Methods Each subject underwent HRT II, RTA, and StratusOCT examination. Two experienced examiners drew the contour lines for the HRT II and RTA. Bland and Altman plots were used to evaluate agreement for each topographic parameter among the instruments. The Spearman coefficient of rank correlation was evaluated for each topographic parameter. Main Outcome Measures Agreement in the measurement of op…
