“…2 Although Kirwan and colleagues 11 showed that CCT decreased dramatically from approximately 31 weeks to term in 35 infants, Spierer and colleagues 7 found no correlation between PCA and CCT in 53 infants. Autzen and Bjornstrom 3 found no difference between the corneal thickness in the 1st and 3rd postnatal week; however, they determined that the corneal thickness of premature babies at 3 months of age decreased significantly to the to the same level in full-term newborns.…”

“…b P \ 0.001 after correction with age after birth at measurement. CCT decreases after birth in premature 2,3 and in fullterm infants, 4,5 possibly because of better control of corneal hydration, evaporation, and corneal remodeling (increase of corneal diameter and decrease of curvature) [2][3][4][5] ; the value in premature could be lower than previously reported due to greater age after birth.…”

“…Congenital glaucoma is a rare condition that involves an increase in IOP, optic nerve head changes, and deformation of the eye, with an increase of corneal and ocular diameters. Compared with full-term newborns, premature newborns have greater CCT, [1][2][3][4][5] which decreases progressively. [2][3][4][5] A progressive reduction in IOP has also been detected [6][7][8][9] ; however, no data are available on the effect of CCT on IOP measurements in newborns.…”

“…This decrease in IOP is possibly due to decreased CCT. Growth of eye with corneal remodeling and stretching of collagen fibers, evaporation and better control of corneal hydration can be the cause of decreased CCT in premature infants after birth [7].…”

“…There are also variable CCT and IOP values of premature infants at the literature [5,7,[9][10][11] The reported differences can be due to timing of evaluation and variable postconceptional ages of infants during measurement. Contrary to aforementioned studies, Muslubas et al [12] found that premature infants have slightly thicker corneas but similar IOP measurements when compared to term neonates.…”

To evaluate the central corneal thickness (CCT) and intraocular pressure (IOP) of premature infants and to document correlation of them with gestational age, chronological age, and birth weight of infants. Using a hand-held applanation tonometer and a portable pachymeter, IOP and CCT of 170 premature infants were measured just before initial retinopathy of prematurity screening examination and re-measured 4 weeks after the first visit. The CCT and IOP were positively correlated during the first (r = 0.616, p < 0.001) and second (r = 0.564, p < 0.001) visits. The mean CCT at first and second visits were 568.1 ± 22.1 (527-628) and 561.6 ± 21.4 (520-619) µm, consecutively (p < 0.001). Gestational age, chronological age and birth weight of infants were found to be negatively correlated with CCT at first (r = -0.751, p < 0.001; r = -0.745, p < 0.001; r = -0.581, p < 0.001, consecutively) and second (r = -0.729, p < 0.001; r = -0.729, p < 0.001; r = -0.555, p < 0.001, consecutively) visits. The mean IOP at first and second visits were 14.1 ± 1.9 (11-19) and 13.7 ± 1.7 (11-18) mmHg, consecutively (p < 0.001). Gestational age, chronological age, and birth weight of infants were found to be negatively correlated with IOP at first (r = -0.724, p < 0.001; r = -0.715, p < 0.001; r = -0.558, p < 0.001, consecutively) and second (r = -0.704, p < 0.001; r = -0.703, p < 0.001; r = -0.518, p < 0.001, consecutively) visits. CCT and IOP of the premature infants with a smaller gestational age were found to be higher (p < 0.001 for both). Premature infants with smaller gestational age have higher CCT and IOP values when compared to older infants. These values tend to become lower 4 weeks after the first examination as infants become older. The CCT and IOP were positively correlated with each other and both were negatively correlated with gestational age, chronological age, and birth weight during first and second visits.
