Perinatal factors associated with retinopathy of prematurity

Abstract: The etiology of retinopathy of prematurity appears to be multifactorial. Introduction of new treatments in neonatal care may add new risk factors. We have analyzed thc relationship between 42 perinatal factors and the development of retinopathy of prematurity in 78 infants with a birth weight < 1501 g and/or gestational age < 33 weeks. We have also applied a chronological analysis of the maximum and minimum pO2 and pCO2 values. Retinopathy of prematurity was seen in 37 of 78 infants (47.4%). Nineteen factors w… Show more

“…We could not find any significant difference among the singleton or multiple gestation group. Rohit et al 21 also did not Many studies 6,14,[16][17][18] have poven the role of hyperoxia in the pathogenesis of ROP. In our study prolonged duration of oxygen inhalation (>140 hours) was significantly associated with abnormal examination findings.…”

“…Immaturity per se seems to be the most important risk factor (Majima 1977, Bossi et al 1984, Darlow et al 1992, Schaffer et al 1993. Oxygen supply also seems to be related to the development of ROP (Lucey & Dangman 1984), but since hyperoxia (Patz et al 1952, Kinsey et al 1977, fluctuations of oxygen (Gallo et al 1993, Lucey 1988, Saito et al 1993) as well as hypoxia (Ashton & Henkind 1965, Johnson et al 1978, Lucey et al 1981) have been associated with the condition, the pathogenetic role of oxygen, as related to modern neonatology principles, remains enigmatic.…”

“…The etiology of ROP remains obscure, and is thought to be multifactorial (Majima 1977, Bossi et al 1984, Purohit et al 1985, Hammer et al 1986, Darlow et al 1992, Schaffer et al 1993, Gallo et al 1993).

“…These have included low gestational age at birth, 7 ± 12 low birth weight, 5,10,12 ± 14 male sex, 9 white race, 12,15 bronchopulmonary dysplasia, 5,10,13,16 sepsis, 8,13 acidosis, 7,11,16 oxygen therapy, 14,17 hyperoxia, 2,11,18 hypocarbia, 19 hypoxia, 1,11,19 and maternal use of beta blockers immediately before birth. 14 Recently, a case of neonatal HIV infection after blood transfusion at another institution led to a decrease in blood transfusions in premature infants at that hospital. Many lower risk infants went on to develop severe ROP, raising the concern that this change in transfusion practice and resultant anemia might be etiologically important ( J. O'Neil, personal communication, April, 1998).…”
