Objective To evaluate the repeatability and reproducibility of macular ganglion cell-inner plexiform layer (GCIPL) thickness measurement using spectral-domain optical coherence tomography (Cirrus HD-OCT). Method One hundred and eight eyes of 54 normal subjects (26 males and 28 females) between 19 and 75 years of age were included. Each eye underwent macular scanning using Cirrus HD-OCT Macular Cube 512×128 protocol by two operators. Three scans of each eye were obtained by each operator. For the right eye of each subject, three extra scans were obtained using Macular Cube 200×200 protocol by one operator. The average, minimum, superotemporal, superior, superonasal, inferonasal, inferior, and inferotemporal GCIPL thickness was analyzed and the repeatability of GCIPL thickness measurement was evaluated with intra-operator, inter-operator, intra-protocol, and inter-protocol intraclass correlation coefficients (ICC). Ten extra scans were obtained from the left eyes of 10 randomly selected subjects for reproducibility assessment with coefficients of variation (CV). Results The intra-operator ICC of macular GCIPL measurement using Macular Cube 512×128 protocol by two operators were 0.959-0.995 and 0.954-0.997, respectively; and the inter-operator ICC were 0.944-0.993. All intra-and inter-operator ICC were > 0.800 with the highest and lowest records of the average and minimum GCIPL thickness, respectively. The intra-protocol ICC of Macular Cube 512×128 protocol and Macular Cube 200×200 protocol were 0.986-0.996 and 0.927-0.997, respectively; and the inter-protocol ICC were 0.966-0.994. All intra-and inter-protocol ICC were > 0.800. CV of GCIPL thickness measurement using Macular Cube 512×128 protocol were (0.70±0.31)%-(1.35±0.86)%. Conclusion Cirrus HD-OCT can measure macular GCIPL thickness in normal eyes with excellent repeatability and reproducibility.
