ABSTRACT
Objective: The aim of this study is to evaluate the relation between pterygium and ocular dominance.
Method: In this cross-sectional study a total of 58 patients who had unilaterally pterygium and 60 healthy participants without pterygium were enrolled. Patients’ dominant eyes were been determined by using Dolman’s method (hole-in-the-card test). Clinical and demographic features (such as age, gender) of the patients were noted. Snellen’s best corrected visual acuity, slit lamp biomicroscopic examination were evaluated. Any association with pterygium side and dominant eye side was investigated.
Results: The mean age of the 58 patients suffered from pterygium (34 M, 24 F) was 45.7 ± 12.2 years. Forty four patients’ right eye (75.9 %) and 14 patients’ left eye (24.1%) were dominantin patients with pterygium. Twenty seven of 44 right eye dominant patients had pterygium at their right eye (61%) and 10 of 14 left eye dominant patients had pterygium at their left eye (71%). There was a significant relation between dominant eye and pterygium side (Phi = 0.281 and p = 0.032).
Conclusions: In participants of both with or without pterygium, right eye seems to be dominant more frequently. Moreover, pterygium is more frequently occurs in the dominant eyes.
