Association of net pterygium tissue mass (dryweight) in determining changes in oculovisual functions and anterior corneal curvature relative to pterygium types

Introduction: Dryweight in pterygium is more towards the fleshy appearance of the fibrous tissue. Aim: The goal of this study was to determine the predictive ability of net pterygium tissue mass (dryweight) on predicting changes in anterior corneal cur-vature and oculovisual functions relative to pt...

For CSF, the predictive ability of pterygium dryweight were strong in all types with Type I, Type II and III reported 21.6% (R2 = 0.216, p < 0.05), 31.8% (R2 = 0.318, p < 0.05), 28.9% (R2 = 0.289, p < 0.05) respectively.
