Patients attending eye department with refractive error were selected for study. Emmetropic patients attending eye department for other complaint also taken for study.retinal nerve fiber layer thickness was measured in 600 patients (200 hypermetropia, 200 myopia, 200 emmetropia) attending eye department from 15 September 2010 to 15 May 2012 by Spectral domain optical coherence tomography.
Retinal nerve fiber layer thickness thickness in inferior, nasal ,superior, temporal quadrants in emmetropic patients were 149.8 +_22 micrometer,140.4+_23 micrometer,86.2 +_24 micrometer,83.2+_18 micrometer respectively. Mean ± Standard Deviation for retinal nerve fiber layer thickness thickness in inferior, superior, nasal and temporal quadrants in hypermetropes were 160 ± 15μ, 152.5 ± 12μ, 9 4.8 ± 12μ, 81.68 ± 11μ respectively. Myopes had decreased retinal nerve fiber layer thickness thickness than emmetropes and did not follow ISNT rule (inf-131.2+_ 20 micrometer, sup-118.4+_ 20micrometer, nasal-64.12 +_ 14micrometer, temp- 80.20 +_18 micrometer). Increased retinal nerve fiber layer thickness thickness was observed in hypermetropic patients as compared to emmetropes, myopes and follows ISNT rule. Differences in retinal nerve fiber layer thickness thickness amongst myopes, hypermetropes and emmetropes were statistically significant (p < 0.05) in all except temporal quadrants.
Optical coherence tomography measured retinal nerve fiber layer thickness thickness provides a guide in refractive status of eye
