Abstract
- The purpose of this study is to find out what changes occur in the corneal curatures before and after the operation for pterygium and the relationships between the histopathologic findings and the various factors concerned with pterygium. The results are as follows: 1. The degree of corneal invasion of the pterygium head is closely related to the difference between the horizontal and vertical corneal curvatures before operation. 2. The difference between the horizontal and vertical corneal curvatures decre ase after operation. 3. The changes in horizontal curvatures are remarkable in 3 weeks after surgery with a mean change of +0.41 D. 4. In the histopathologic findings, the duration of pterygium and the increased amount of collagen fiber are significantly related(p<0.01). 5. There is no relationship between the histopathologic findings and the changee in corneal curvatures analysed by the SPSS program (p>0.05).
