Keratograph 5M As A Useful And Objective Tool For Evaluating The Ocular Surface In Limbal Stem Cell Deficiency

Figures & data

Figure 1 Sector plot of the etiology of limbal stem cell deficiency. The corresponding percentages for each group are shown. Each etiology is represented with a different color.

Figure 2 Bland-Altman plot of the relationship between the classical self-administered Ocular Surface Disease Index (OSDI) and the Keratograph 5M OSDI. The measures were encompassed between the mean and two standard deviations following a linear pattern, demonstrating that the results of the two tests were very similar.

Figure 3 Bland-Altman plot of the relationship between the keratograph noninvasive tear break-up time (NIKBUT) and tear break-up time (BUT). The two tests fit one another, forming an almost horizontal line, showing linearity. Almost all values were between the mean and two standard deviations.

Dry Eye Level	First Keratograph 5M Noninvasive Tear Break-Up Time	Mean Keratograph 5M Noninvasive Tear Break-Up Time
Stable	≥10 seconds	≥14 seconds
Suspected	6–9 seconds	8–13 seconds
Abnormal	≤5 seconds	≤7 seconds
“Too short of a time”	≤1.5 seconds
