Abstract:
AIM:To determine tear function tests values,Schirmer Ⅰ test(S Ⅰt),tear film break-up time(TBUT)in patients with pterygium.METHODS:A total of 100 eyes(50 with primary pterygium and 50 without pterygium)of 50 patients who fulfilled the inclusion criteria were evaluated for S Ⅰt and TBUT.RESULTS:The mean S Ⅰ t value in eyes with pterygium was 19.6±11.6(range 1-40)mm and in control eyes without pterygium was 17.2±10.6(range 1-35)mm.S Ⅰ tresults were abnormal in 20 eyes(40%)with pterygium and in 21 eyes(42%)without pterygium(control);the difference was not statistically significant(P= 0.75).The difference between the groups was not statistically significant(f= 1.453,P=0.15).The TBUT in eyes with pterygium was 7.4±5.1(range 2-20)seconds and in control eyes without pterygium was 13.4±6.1(range 2-25)seconds.The difference between the groups was statistically significant(f = 8.029,P＜0.01).The TBUT was abnormal in 39 eyes(78%)with pterygium and in 16 control eyes(32%);the difference was statistically significant(P＜0.01).CONCLUSION:There was no significant difference in S Ⅰ t in eyes with pterygium compared to eyes without pterygium.There is reduction of TBUT in eyes with pterygium.
