Comparison of Tear Film Breaking Time Measured Using New Generation and Traditional Methods

surements were recorded. Schirmer test and ocular surface staining scores were applied to all eyes. Results: 59 male and 141 female pa- tients were included in this study. The average age of the patients was 32.71±12.28 (year). Fluorescein break-up time of the patient popula- tion was 4.14±3.84 seconds on average. Topographically, mean first tear film break-up time was 4.32±2.75 seconds,mean last tear film break-up time was 10.6±4.01 seconds and the average tear film breakup time was 7.37±3.10 seconds. A statistically significant difference was not found between fluorescein break-up time and first non-inva-sive break up time. (p=0.114). Conclusion: Corneal topography de- vices which can measure tear film breaking can be an alternative to conventional methods for evaluating tear film layer. The advantage of measurement by corneal topography is being non-invasive, as well as documenting the refraction map of the tear film layer.
