FP407 : Macular and retinal nerve fiber layer thickness in normal, glaucoma suspect and glaucomatous eyes

Dr.SABYASACHI BANDYOPADHYAY

Purpose: To evaluate the Peripapillary retinal nerve fiber layer and macular thickness parameters in controls, glaucoma suspects and glaucoma patients by time domain optical coherence tomography (TD-OCT). Methods: One eye of 70 controls, 35 glaucoma suspects and 70 glaucoma patients were included. The discriminating power of each parameter between the groups was determined by area under the receiver operating characteristic (AROC) curve. Results: All the macular thickness parameters between the groups were statistically significant (p< 0.05) except foveal thickness (FT) and nasal inner (NI) quadrant thickness. The temporal outer (TO) macular quadrant produced largest AROC curve of 0.90 between controls and glaucoma patients. RNFL parameters were significant between the groups (p<0.001). The AROC curve between control group and glaucoma patients for RNFL average thickness was 0.99. Conclusion: RNFL and macular thickness parameters had high discriminating power between the study groups.
