%X The percentage of cells stained for Hsp90 was greater for pterygium epithelium (76 +/- 10.8) than for normal conjunctiva (1.4 +/- 0.8). In each pterigyum sample more than 60% of cells were positive. The differences in positive cells between normal and pterigyum epithelium were highly significant for Hsp90 (P < 0,001). Pterygium epithelium also showed a higher percentage of cells that stained for Ki67 (10.1 +/- 9.5) than for normal conjunctiva (2.1 +/- 1.9). The differences in positive cells were also statistically significant for Ki67 (P < 0.01). Although there were significant differences in the majority of samples observed. It was noted that in some samples there was no difference between normal and pterygium epithelium for Ki67.Our results indicate an abnormal expression of Hsp90 and ki-67 in pterygium samples when compared to normal conjunctiva.The finding of abnormal expression of levels of Hsp90 in pterygium samples can stimulate new research into pterygium and its recurrence.
