Abstract
Purpose: To evaluate the correlation between corneal astigmatism and pterygium morphology by anterior segment optical coherence tomography. Methods: Patients diagnosed with unilateral pterygium were included in this prospective crosssectional study. A thorough history was taken and each patient underwent detailed ocular examination including demographic data, subjective refraction with best corrected visual acuity using a Snellen’s chart, anterior and posterior segment examination with slit lamp biomicroscopy , keratometric measurements using an autorefractometer. The vertical width and horizontal length of the pterygium was measured manually with the millimetric scale of the slit lamp biomicroscope. Results: The study consisted of 45 patients with a mean age of 54.58 years. Mean Horizontal pterygium length, vertical width and percentage extension of pterygium was 2.71 mm, 4.56 mm, 50.22% respectively. Mean anterior corneal astigmatism was 2.11±1.69. Analysing the correlation separately, a statistically significant correlation was present between horizontal length and percentage extension and the anterior corneal astigmatism. Conclusion: Anterior corneal astigmatism was higher in pterygium group as compared to the contralateral eye without pterygium.
