Aim: Cirrus spectral-domain optical coherence tomography (SD-OCT) being noninvasive is gaining more popularity in identifying, monitoring, and classifying children with vitreo-retinal disorder. Normal values of cirrus SD-OCT from children are currently available from developed countries, but not from India. Objective: The primary objective of this study is to provide a normative pediatric database for macular thickness in healthy Indian children using the cirrus SD-OCT. Materials and Methods: The prospective observational study on 157 consecutive healthy children seen between January 2013 and January 2014. Included in the study were 157 subjects with no ocular abnormality, normal (20/20) visual acuity and normal fundoscopy. Cirrus HD-OCT (Carl Zeiss, Dublin, California, USA) device was used. Outcome: Study patients have a mean age of 12.59 ± 3.5 years, with 112 male (12.88 ± 3.5 years) and 45 female (11.8612.88 ± 3.5 years) children. In the linear regression analysis, changes in central subfield thickness and field of the outer macula were independently affected by increase in the age (β = −1.17-1.7, P = 0.004-0.022) and male are found to have significantly higher value when compared with the female (the t-test; t = 1.9-4.8, P = 0.00-0.24). Conclusion: This study established normal reference values for macular parameters measured by Cirrus SD-OCT in healthy Indian children 6-17 years of age, which is statistically different from the databases from other countries. It establishes the importance of the fact that age and gender warrants special consideration during cirrus SD-OCT interpretations in children.
