Abstract:
Background and Objectives: Several methods exist to evaluate tear film, the most widely used of which is the tear break-up time (TBUT) test. This test is an invasive method that involves the use of fluorescein and stimulates the tear reflex. A chief security officer (CSO) company has added a feature called non-invasive tear film breakup time (NIBUT) to the new version of its OCT device, MS-39, which checks dry eyes without using fluorescein. In this research, the aim is to compare the results of these two methods to examine dry eyes. Methods: The evaluation starts with measuring NIBUT in MS-39

Background: The prevalence of dry eye disease (DED) is increasing globally, resulting in a variety of eye symptoms characterized by discomfort and visual disturbances. The accurate diagnosis of the disease is often challenging and complex, requiring specialized diagnostic tools. This study aimed to investigate the impact of tear film instability on visual function and to evaluate the value of post-blink blur time (PBBT) as an alternative method for assessing tear film stability. Methods: The study included 62 subjects: 31 with subjective symptoms of DED (Group A) and a control group consisting

Mucin deficiency is a possible cause of tear film instability. The important sources of mucin are the conjunctival goblet cells and the non-goblet conjunctiva! epithelial cells where the mucin-like glycoproteins are stored in the mucous secretory vesicles. This thesis addresses the relationship between the quantity of the mucin sources and tear film physiology in a group of normal to marginal dry eye Chinese subjects. Chinese subjects were used in this study because they were found to have a lower tear break-up time than Caucasians (Cho and Brown, 1993). Impression cytology techniques were

Abstract:
Dry eye syndrome is a common disorder of the tear film which affects a remarkable percentage of the population. The Break-Up Time (BUT) is a clinical test used for the diagnosis of this disease, which computes the time the first tear film break-up appears. This work describes a fully automatic methodology to compute the BUT measurement and evaluate the break-up dynamics until the final blink. This analysis provides useful additional information for the assessment of tear film stability.

In this work, we propose several improvements for the automatic computation of the BUT measure that solve the limitations of previous approaches. In particular, we present several procedures for the automatic computation of some parameters involved in the BUT measurement, such as the eye size, the intensity variation, or the starting point of the measurement frame sequence.
