| Summary: |
Purpose of this
study was to compare the results of pVEP and pERG
examinations between pre-term and in-term born ten years
old children.
Material and methods: We examined 45 pre-term
born and 21 in-term born children. In 14 cases of
pre-term born children cryotherapy was performed
following retinopathy of prematurity (ROP), remaining
group of 27 children had not presented clinical features
of ROP or in whom spontaneous regression had occur. All
participants underwent ophthalmic examination and were
tested with pVEP and pERG.
Results: The mean amplitude of P100 for 1o
pattern was: in the group of in-term born children 22.5
µV, in pre-term born children without cryocoagulation –
20.0 µV, and after cryocoagulation – 19.0 µV. The mean
implicit time of P100 was: 99 ms, 101.37 ms i 102 ms.
For 0.3 pattern the mean amplitude of P100 was: 21.6;
17.7 and 14.4 µV, and implicit time – 103.9; 105.2 and
110.1 ms. There was no difference in amplitude and
implicit time of P50 and in implicit time of N95 pERG
between 3 groups. The amplitude of N95 was the biggest
in in-term born children, and the smallest in pre-term
born children after cryocoagulation.
Conclusions: In the group of pre-term infants
especially those treated with cryotherapy the authors
revealed a significant reduction of the P100 amplitude,
prolonged latency, and reduction of N95 amplitude in
comparison with in-term born children. |
