Objective:
Twenty cases of PWS were measured by means of Derma Spectrometer with the goal of estimating PWS condition.
Materials And Methods:
Twenty patients of PWS were chosen randomly in this study. Derma Spectrometer was used to detect lesion and control sides pre- and post- laser treatment.
Results:
The mean normal skin's M-Index was (36.18+/-6.45)%, E-Index was (1.39+/-4.85)%. Lesion's M-Index and E-Index were (44.85+/- 6.61)%, (13.05+/-6.30)%. Lesion's M-Index and E-Index after one treatment were (41.00+/-5.30)% and (9.04+/-4.98)%. Significant difference existed between normal and lesion's M-Index. Also there were difference among normal skin, lesion and lesion treated.
Conclusion:
There is difference between normal and lesion M-Index. But none for lesion and lesion treated. Different E-Index were among normal skin, lesion and treated lesion. The E-Index was decreased at treated lesion. It suggested blanch of PWS after laser treatment. Derma spectrometer has the role of evaluation of PWS.
