A healthy tear film is very important for many major functions of the ocular surface. Dry eye disease is a significant clinical problem that needs to be solved, but the poor correlationThe patterns of crystallization (ferning) are classified in 4 classes: Type 1: uniform large arborization, Type 2: ferning abundant but of smaller size; Type 3: partially present incomplete .Tear Ferning Test. The tear ferning test is a simple tear detection method that can reflect some biochemical characteristics of tear film relatively quickly and cheaply (see Figure 3) (44, 54).
The tear ferning test is a laboratory test but it has the potential to be applied in the clinic setting to investigate the tear film in a simple way. Drying a small sample of tear fluid.
The tear ferning patterns of smokers show less branching and ferning when compared to patterns of non-smokers, showing the negative impact of cigarette smoke on tear film quality.

The tear ferning test has the right features for use in the eye clinic for dry eye diagnosis [7-9]. Pearce and Tomlinson studied tear film ferning with light and electron microscopy, and they discussed the role of chemical elements, such as sodium (Na), potassium (K), chlorine (Cl), and sulfur (S), in the formation of ferning. The tear ferning test in healthy cats is described and compared and it is thought that Masmali grade 2 can be considered a normal tear pattern for the species, because all the cats used in study were clinically healthy. Background The tear film is a trilaminar fluid composed mainly of lipids, electrolytes, proteins and water. It is responsible for lubrication, nutrition and .The tear ferning (TF) test has recently been described as a simple, fast, and inexpensive method to indirectly assess tear quality. 13, 14 The TF test involves dropping a tear sample onto a glass slide and allowing the sample to desiccate under normal room temperature and humidity to produce a crystallization pattern that can be examined under . The correlation is not exact, with some apparently normal tear films yielding abnormal ferning patterns. It may be that tear ferning yields additional information on tear film health not provided by the Schirmer tear test and that tear ferning can be a valuable technique in the evaluation of ocular surface pathology in the dog.

The tear film is a trilaminar fluid composed mainly of lipids, electrolytes, proteins and water. It is responsible for lubrication, nutrition and protection against microbial and toxic agents. Disruption of any these components may weaken the ocular surface, making it more susceptible to disease. Increasing evidence suggests that qualitative tear film deficiencies are .

composition. Practical insight into tear film composition would be very useful to the clinician for patient diagnosis and treatment, but detailed analysis is restricted to expensive, laboratory-based systems. There is a pressing need for a simple test. The tear ferning test The tear ferning test is a laboratory test but it has the potential to be applied in the clinic setting to investigate the tear film in a simple way. Drying a small sample of tear fluid onto a clean, glass microscope slide produces a characteristic crystallisation pattern, described as a .The tear ferning test is a simple tear detection method that can reflect some biochemical characteristics of tear film relatively quickly and cheaply (see Figure 3) (44, 54). Golding et al. ( 55 ) pointed out that the salts and polymers in tears are the important factors affecting the crystallization of tear ferns in the microscopic . The tear ferning test is an uncomplicated, non-invasive, inexpensive and speedy laboratory and clinical procedure which can be used as a first-line evaluation of altered tear health. .

The tear ferning test (TFT) is a qualitative test developed for humans, and it has become a useful diagnostic tool in tear ferning research. Various ferning patterns can be observed as a result of tear crystallization after evaporation of lacrimal samples, and these patterns depend mostly on TF composition [ 8 ].
The tear ferning patterns are probably different also in Asian eyes compared to Caucasian population and limited studies of tear ferning have been reported as compared to Caucasian. Results from this study may help in understanding the health of the ocular surface and stability of pre-ocular tear film of the Asian population. The tear ferning test is a qualitative test that can be used in cats as a complementary evaluation of the ocular surface. While the Rolando scale showed an increased prevalence of types I and II, the Masmali scale showed an increased prevalence of grades 1 and 2. . Background: The tear film is a trilaminar fluid composed mainly of lipids .

In particular, the mucous component of the tear film was evaluated by tear ferning test (TFT), dosing of MUC5AC levels, and density of conjunctival goblet cells. In addition, modifications of TFT, MUC5AC levels in tears and conjunctival goblet cell density were compared to clinical features and evaluated prior and after treatment with topical CY.TEST Tear ferning test (TFT) REFERENCES TO DIAGNOSE Quality of tears (electrolyte concentration), KCS, Hyperosmolarity VERSION of TEST [V1] T ea rf nig ts ( c ol by d) .

Another potential use .

There is a pressing need for a simple test. The tear ferning testThe tear ferning (TF) test is known as a quick, simple, and inexpensive test for tear sample assessment. It is performed by putting a drop of tear sample on a glass slide, and allowed to air dry in order to form the TF patterns. 19 The previous studies have shown good sensitivity, specificity, and repeatability 20, 21 using the TF test. In our previous study, the mouse TF test .

Several clinical tests are available to examine tear film quantity (i.e., tear volume) and quality (i.e., tear film stability). 5, 6 Tear quantity can be determined using Schirmer's test or the phenol red thread test, 7 and tear quality can be assessed by measuring tear break-up time (TBUT). 8 Also, tear osmolarity can reflect some aspects of . Schirmer tear test (STT) is often the only diagnostic test used to assess for DED in veterinary practice. STT is invaluable in the diagnosis and monitoring of quantitative tear film deficiency (i.e., keratoconjunctivitis sicca); however, it is not sufficient to optimize therapy and fully recognize other contributing factors for the disturbance .
