Purpose : In this study we investigated whether elevated serum Alkaline phosphatase (ALP) is related to prevalence, location, type, recurrence of pterygium and also length in the South Korean population.

Methods : A national wide cross-sectional study data Korean National Health and Nutrition Examination Survey form 2008-2011 was used in this study. Participants over 30 years old, performed both ALP test and ophthalmic evaluation were included (N = 22359). One-way analysis of variance, chi-square test, and Fisher’s exact test were used to compare characteristics and outcomes of the participants. Multivariable logistic regression was used to examine the association between serum ALP level and various type of pterygium. Known risk factors for development of pterygium and ALP elevation were adjusted (age, sex, residence, sunlight exposure, drinking, smoking, hypertension, diabetes, BMI, AST, ALT, Vitamin D and HDL)

Results : The overall prevalence of pterygium was 8.1% and subjects with pterygium had higher level of serum ALP (P <0.001). Subjects with higher serum ALP had significant higher prevalence of all types of pterygium than those of lower serum ALP quartiles. After adjusting potential confounding factors, multivariate logistic regression analysis showed that ALP was associated with the prevalence of pterygium(OR:1.001, p-value: 0.038) . Trend analysis between odds ratio and ALP quartiles showed linear trend in overall prevalence and in intermediate type of pterygium. Subgroup analysis stronger correlation in participants aged over 50. One way ANOVA showed association between size of pterygium and serum ALP quartile levels. Serum ALP did not show association with recurrence of pterygium.

Conclusions : Increased serum ALP was related to prevalence and size of pterygium.
