Background and Objectives: To retrospectively analyze changes in incidence and risk factors of retinopathy of prematurity (ROP) over two periods, 10 years apart, in the central Netherlands. Methods: Data of 570 infants admitted between 2001 and 2005, screened for ROP according to the Dutch National guideline, were compared to those of 538 infants admitted between 1991 and 1995. Results: Incidence of ROP decreased significantly over the last decade (40.9% in 1991–1995 vs. 23.3% in 2001–2005, p < 0.001), together with incidence of severe ROP (stage ≧3) (3.3 vs. 1.2%, p < 0.05). In infants with a birth weight (BW) <1,000 g incidence of ROP dropped significantly (67.0 vs. 41.8%, p < 0.001), as well as incidence of severe ROP (8.1 vs. 3.0%, p < 0.05). For infants with a BW ≧1,000 g incidence of ROP also declined significantly (27.1 vs. 13.0%, p < 0.001), that of severe ROP remained unchanged (0.8 vs. 0.3%). In both periods gestational age, duration of artificial ventilation, small for gestational age (SGA) and postnatal steroids were independent risk factors for ROP. Conclusions: In the central Netherlands, incidence of ROP and severe ROP has significantly decreased, also in infants with BW <1,000 g. Risk factors remained unchanged.

“…Ophthalmoscopy to detect ROP was performed from the age of 5 weeks onward as soon as the infants condition permitted, following the screening strategy described by Tan and Cats [22]. To obtain maximum mydriasis, tropicamide 0.5% and phenylephrine 2.5% eye drops were instilled every 15 min during the hour before the investigation of the eyes.…”

Surfactant replacement therapy: A new risk factor in developing retinopathy of prematurity?

et al. 1994

We documented the prevalence of retinopathy of prematurity (ROP) in a group of 46 infants suffering from a moderate or severe respiratory distress syndrome and treated with surfactant replacement therapy (SRT) and 61 controls admitted in the year prior to the institution of SRT. Mortality in the treatment group was lower than in the control group (15.5% versus 23.8; P = 0.29). The ROP prevalence in the treatment group was 47.8% and in the control group 27.9%. To analyse the contribution of SRT alone to the prevalence of ROP, multivariate analysis using logistic regression technique was used. The odds ratio for SRT was 5.2 with a 95% confidence interval of 1.3-20.7, P = 0.02. The prevalence of severe ROP in the surfactant treated group was not increased compared to the control group. From our data we conclude that SRT increases the risk of developing ROP but is not associated with more severe forms of ROP.

“…In our study the mean postnatal age and the mean postmenstrual age at onset of ROP was 7 9 weeks (range 3-16) and 36 weeks (range [31][32][33][34][35][36][37][38][39][40][41][42][43] respectively. As 48 of the 260 children already had some degree of ROP at their first examination, these results may, however, be interpreted with caution.…”

A prospective population based study including 260 children with a birth weight of 1500 g or less was performed in the Stockholm county. The total incidence of retinopathy of prematurity (ROP) was 40*4%, while severe ROP -that is, stage 3 or more, was seen in 20.0%. Cryotherapy was performed in 10.8%. Logistic regression analysis revealed independent association of both gestational age and birth weight with ROP. The association of gestational age and ROP was significantly stronger, indicating that the degree of immaturity of the eye is a main predictive factor for the development of ROP. The purpose of a general screening for ROP is to identify children requiring cryotherapy. Based on these results it seems appropriate to include children with a gestational age of 32 weeks or less in such a programme and a first examination at 5-6 weeks of postnatal age is suggested.
