  • Abstract
  • Look Inside

We quantitated the corneal curvature in 67 eyes of 62 patients with pterygium located in the nasal sector. We used a corneal analysis system, EyeSys, which measures 360 points for each of 16 projected mire rings. The coefficient of variation, CV, was calculated and analyzed for the size of pterygium. The distance of the advancing top of the pterygium from the center of the cornea showed higher correlation with the CVs than the width of the pterygium at the limbus. Corneal distortion became more pronounced when the tip of pterygium advanced to less than 3 mm from the corneal center.
