Abstract
This paper is aimed to find the prevalence of pterygium among the patients who had hemoglobin E containing diseases. Patients and Methods: The cross-sectional study was conducted among the patients with Hb E trait, Hb E disease, Hb AEBart, Hb CS-AEBart, beta-thalassemia/Hb E, Hb EFBart and Hb CS-EFBart diseases. They were examined for the presence of pterygium. Results: From 124 cases, pterygia had been observed in 28 cases (22.6 %), 12 cases having pterygia in both eyes (9.7%) and 16 cases having pterygium in only 1 eye (12.9%), 10 in the right eye and 6 in the left eye. The severity of pterygia consisted of grade 1 of 34 eyes, grade 2 of 4 eyes and grade 3 of 2 eyes. Conclusion: The prevalence of pterygium in the patients with hemoglobin E containing diseases is rather high. It cannot be solely explained by the sun exposure alone. However the true association needs further investigations.
