HERNANDEZ, M. et al. Retinopathy of prematurity in the Murcia Region of (Spain): Incidence and severity. Arch Soc Esp Oftalmol [online]. 2008, vol.83, n.7, pp.423-428. ISSN 0365-6691.

Objective: To determine the incidence and severity of Retinopathy of Prematurity (ROP) in the Murcia region of Spain. Methods: This was a retrospective study of all infants born preterm in the Murcia region during 2004, who were screened for ROP. Our screening criteria were: Infants with a gestational age ≤ 32 weeks (GA) or with a birth weight ≤ 1500 g (BW). We evaluated sex, GA, BW, parity and ophthalmologic evaluation. We then performed a descriptive study and a statistical analysis. Results: The study sample involved 115 infants with an average GA of 29.67 weeks and BW of 1325 g. The incidence of ROP and severe ROP was 32.1% and 15.6% respectively. The likelihood of the premature infant developing severe ROP was found to be 88.8% if it was born before  29 weeks GA or weighed less than 1000g BW. Significant differences (p < 0.001), in terms of GA and BW between infants with and without ROP, were found. Conclusions: A third of the preterm infants screened for ROP in the Murcia region developed the disease, and the 50% of these required treatment. The current screening criteria used in our region are appropriate. If more restrictive criteria were used, some severe ROP cases would not be detected. In order to be able to modify the current guidelines for screening for ROP, further studies are required.
