The 5-minute Apgar score as a prognostic factor for development and progression of retinopathy of prematurity.Folia Medica 2017;59(1): 78-83. doi: 10.1515/folmed-2017-0011 Background: A low Apgar score at 5 minutes has been shown to be a risk factor for development of retinopathy of prematurity (ROP). Aim: To examine the prognostic value of Apgar score at 5 minutes for development and progression of ROP.
Materials and methods:The study included 132 preterm infants who were screened from 4th week of life onward. Of these, 118 newborns were given Apgar score at 5 minutes. The prognostic signifi cance of this index was studied as an absolute value and as a value ≤ 6. The patients were divided into two groups: group I had no evidence of ROP (n=82) and group II had some signs of ROP (n = 36). Group II was further divided into group IIA -spontaneously regressed cases (n=22), and group IIB with cases which progressed to treatment stages (n=14). We investigated 15 maternal and 20 newborn presumable risk factors for development and progression of ROP. Mann-Whitney U test, χ 2 or Fisher's exact test were used in the statistical analysis. Logistic regression was performed to fi nd signifi cant and independent risk factors for manifestation and progression of ROP. Results: A low 5-minute Apgar score and an Apgar score of 6 or less at 5 minutes were not statistically signifi cant risk factors of ROP (р=0.191, р=0.191, respectively), but were signifi cant risk factors for the manifested ROP to progress to stages requiring treatment (p=0.046, р=0.036, respectively). Conclusion: An Apgar score at 5 minutes of 6 or less was a signifi cant and independent risk factor for progression of ROP to stages requiring treatment.
