Abstract: The purpose is to compare the ability of spectraldomain optical coherence tomography (SDOCT) retinal nerve fiber layer (RNFL), optic nervehead (ONH), and macular measurements (GCC) todetect glaucomatous damage. Methodology: This study was prospective, cross-sectional observational study.All patients went under the detailedglaucoma Workup.Patients were categorized in control group, pre-perimetry, Glaucoma with Normal visual field and Glaucoma with Visual field changes. Optic Nerve Head (ONH), RNFL parameters and Macular measurements (GCC) were tested by SDOCT. Results: Total 204 eyes of glaucoma patients were included with mean age M=57.55, SD=10.60. Oct ONH, Average RNFL and GCC analysis was done. Mean Average RNFL showed significant change between control (92.29?10.23) and glaucoma group(67.17?14.12)p<0.05.Average GCC+IPL in control group (80.15?6.51) and glaucoma patients(62.74?13.52)p<0.05. Diagnositic ability was tested in Average RNFL (0.80) and Average GCC (0.77) were found to be largest AUC curve. Conclusion: Our results have significant implications for the use of the SDOCT technology for diagnosing structural damage in eyes havingglaucoma.
