Abstract

Purpose: To quantify normal Corneal transparency by Anterior segment optical coherence tomography (AS-OCT) by measuring the average Pixel intensity. To analyze the variation in the average Pixel intensity in Mild and severe grades of corneal opacities. Methods: This is an observational, cross-sectional study of 38 eyes from 19 patients with mild or severe grades of corneal opacities greater than 3 mm and a normal contralateral cornea. AS-OCT was performed centered on the opacity with a 3 mm cruciate protocol. A similar image is taken of the contralateral clear cornea in the same quadrant. The average Pixel intensity was calculated in a standardized manner using MATLAB software. Result: The average Pixel intensity of the normal cornea was 99. 6 ± 10. 9 [standard deviation (SD)]. The average Pixel intensity of the mild and severe corneal opacities was 115. 5 ± 9. 1 and 141. 1 ± 10. 3, respectively. The differences were statistically significant. Conclusions: AS-OCT images can be used to quantify Corneal transparency. Average Pixel intensity is a measure that varies significantly with varying corneal opacification.
