CORRELATION BETWEEN THE RETINAL NERVE FIBRE LAYER (RNFL) PARAMETERS MEASURED USING STRATUS OPTICAL COHERENCE TOMOGRAPHY AND GDx VCC (SCANNING LASER POLARIMETRY) IN ESTABLISHED GLAUCOMA PATIENTS IN SOUTH INDIAN POPULATION
Journal Title: International Journal of Medical Research & Health Sciences (IJMRHS) - Year 2013, Vol 2, Issue 3
Abstract
Purpose: Optical Coherence Tomography and Scanning LASER polarimetry (GDx) are investigatory modalities used to evaluate the structural changes in the optic nerve and retina in glaucoma patients.This study aims to evaluate the correlation between the Retinal Nerve Fibre Layer (RNFL) parameters measured using Stratus-OCT (optical coherence tomography) and GDx VCC(scanning laser polarimetry) in established glaucoma patients in South Indian Population. Materials and methods: Prospectively planned cross sectional study of 67 eyes of 34 established glaucoma patients on medical management The mean age of patients was 46.911 years (SD+13.531). A complete ophthalmic examination, automated perimetry with octopus interzeag 1-2-3 perimeter, retinal nerve fiber analysis with GDx VCC and Stratus OCT was done. Correlation coefficients between the parameters of OCT and GDx VCC were calculated. Results: Statistically significant positive correlations were observed between GDx VCC and OCT parameters in the respective areas. Conclusion: The RNFL thicknesses measured by two different investigatory modalities OCT and GDx are well correlated despite the differences in values of RNFL thickness.
