 Objective To study the normal intraocular pressure (IOP) and its influencing factors in infants aged 0-3 years. Design Cross-sectional survey. Participants 514 cases of normal infants aged 0-3 years. Methods Under the sedation of chloral hydrate, IOP in supine position was measured three times in each eye with AccuPen hand-held digital tonometer. The central corneal thickness was measured by hand-held corneal thickness gauge. Pearson correlation analysis was performed between IOP and corneal thickness. Main Outcome Measures IOP. Results The mean IOP in the right eye was (15.63±2.76) mmHg, and that in the left eye was (16.17±2.66) mmHg. There were 454 cases in 0-12 months group, mean IOP in right eye (15.69±2.82) mmHg), left eye (16.26±2.69) mmHg; 51 cases in 13-24 months group, mean IOP in right eye (15.31±2.16) mmHg, left eye (15.51±2.19) mmHg; 9 cases in 25-36 months group, mean IOP in right eye (14.67±2.92) mmHg and left eye (15.11±2.85) mmHg. There was a weak positive correlation between IOP and central corneal thickness (r=0.302-0.313, P=0.000). Conclusion There is no significant difference in IOP between 0-3 year’s old infants and adults. (Ophthalmol CHN, 2019, 28: 49-51)
