| Summary: |
Purpose: The
subject of paper was to assess: 1. The child's age, when
the threshold retinopathy is diagnosed. 2. To estimate
the correlation between gestational, corrected and
chronological age of the child at the time of the
ophthalmologic surgery. 3. To estimate the effect of the
treatment on the ROP's regress and to find the risk
factors of the progress of retinopathy despite of the
treatment.
Material and methods: We studied 103 children
treated because of the retinopathy of prematurity. The
mean chronological age at the time of the surgery was
74,8 day ± 18,3 and corrected age was 37,7 Hbd ± 3,2. To
assess the risk factors of the progress of the ROP
despite the treatment we formed the group I- 57 children
with the retinopathy's regress after the surgery and
group II- 23 children with unfavorable outcome of the
disease (i. e. partial or complete retinal detachment at
least unilaterally).
Results: Fetal age correlated with corrected age
at the time of the surgery (r=0,57, p<0,0001) and there
was a negative correlation between gestational and
chronological age at the time of the surgery (r = -0,23,
p=0,02). Statistical significance was achieved by the
stage of ROP before the surgery and the effects of the
treatment (chi2=43,8, p<0,0001).
Conclusions: The risk of the threshold
retinopathy before 36 week of corrected age increases
with decreased gestational age. There is positive
correlation between corrected age and gestational age.
The laser photocoagulation performed in appropriate time
stops progression of ROP. The photocoagulation of the
retinopathy is a very important risk factor of the
severe vision impairment when it is made too late (more
than 3rd stage of ROP). The progress of ROP despite of
laser therapy is more likely in the most premature
babies with small weight gain. |
