Intraocular Pressure, Corneal Diameter and C/D Ratio in Normal Newborns

ABSTRACT

Eight-two eyes of 41 normal newborn were examined at their second day of life to determine intraocular pressure with Tonopen and horizontal corneal diameter with caliper and Cup/Disc(C/D) ratio with direct ophthalmoscope under chloral hydrate sedation. It was 13.0 +/- 3.4mmHg, 10.0 +/- 0.4 and 0.3 +/- 0.1, respectively. These values will aid the ophthalmologist in the diagnosis and management of congenital glaucoma.
