Study of Retinal Nerve Fiber Layer Thickness in Myopic Eye in Rajasthani Population

Purpose To find out relationship between Average Retinal Nerve Fiber Layer Thickness and Myopia. Methods A total of 250 myopic eyes were analyzed. Average Retinal Nerve Fiber Layer (RNFL) was measured with OCT (Optical Coherence Tomography) and compared between the two diagnostic groups. Simple Linear Regression analysis was performed to evaluate the relationship between spherical equivalent and Average RNFL thickness. Result Average RNFL thickness decreases with increase in degree of myopia. Linear regression analysis shows positive correlation between RNFL thickness and degree of myopia (r value = 0.5286, p = 0.0001). Conclusion RNFL thickness measurements may be a useful parameter to assess and monitor glaucoma damage in myopic patients.
