EFFECT OF AXIAL MYOPIA ON GANGLION CELL LAYER THICKNESS USING SD- OCT

Dr. Nahar Singh Choudhary, Dr. Vipul Kumar Nagar

Abstract :

Introduction- In myopia, due to axial lengthening of the eyeball , retina is stretched and thinned, so to see the effect on individual retinal layer like ganglion cell- inner plexiform layer (GC-IPL) , Ganglion cell analysis (GCA) is done using spectral domain optical coherence tomography (OCT). Methods- 196 eyes of 106 myopic patients (age>18 year) were assigned to one of three groups according to their spherical equivalent (SE) values. All underwent Cirrus HD-OCT imaging & macular scan done for Ganglion cell analysis (GCA). Effect on GC-IPL in different sectorsaa of macula was evaluated by multiple comparisons and linear regression analysis. Conclusion- The average and all sectors GC-IPL thickness were significantly thinner in high myopia than in moderate and/or low myopia (p<0.01 ). Average GC-IPL thickness showed a significant correlation with SE (p<0.01).
