Abstract

Background: Tear film stability is essential for healthy vision. More than one test should be used to examine tear film status. The tear ferning test is used as a valuable and repeatable tool to examine the quality of tears in animals and human. The current study aimed to report and discuss the most recent use of the tear ferning test to diagnose dry eye in animals and human.

Main text: The tear ferning test involves the collection of a tear sample using a capillary tube. The tears were allowed to dry in a controlled environment, and the patterns produced were observed and inspected using a light microscope. The four-point tear ferning grading scale that included type I or II (normal eye) and types III or IV (dry eye) is used to grade tear ferning patterns. Another grading scale is developed, which consists of five grades and is used in 0.1 increments. A grade > 2 is defined as dry eye. The tear ferning test has been applied to assess the quality of tears among birds, reptiles, and other animals, such as rabbits, cats, dogs, monkeys, horses, and camels. The tear ferning test has been used to investigate the effect of various disorders, such as the thyroid gland, diabetes, high body mass index, high blood cholesterol level, and vitamin deficiency on tear film. The effect of beverages such as green tea and peppermint that are rich in polyphenols on the tear film have been evaluated. Moreover, the effect of eyedrops on the tear film and addition of electrolytes on tear ferning patterns of eyedrops was studied.

Conclusion: The tear ferning test is an easy-to-perform and inexpensive tool to evaluate the quality of tears in animals and human. It can be used in combination with other tests to detect dry eye symptoms.
