PURPOSE : To determine interocular differences in retinal nerve fiber layer and optic nerve head parameters in a pediatric population using Cirrus HD OCT.
METHODS : This was an observational cross-sectional study in 70 healthy children aged 5-17 years with no ocular abnormality except refractive error. RNFL and optic nerve head measurements were performed using the Cirrus OCT machine.Main outcome measures were interocular differences and their correlations with age and gender.
RESULTS : Differences in the average RNFL between right and left eyes were not statistically significant (P=0.060).Among optic nerve head parameters there was no statistically differences except vertical C/D ratio which was significant.(P═0.007). Mean interocular retinal nerve fibre layer thickness differences in superior, superior nasal, and temporal superior quadrants were 10.61 (P < 0.001), 12.57 (P < 0.001),4.46 (P═0.002), μm respectively.Interocular nerve fibre layer thickness differences were not significant
