An interesting use of the study of tear ferning patterns in contactology.
A study of tear ferning patterns in normal and keratoconjunctivitis sicca eyes led to the classification into 4 types by Rolando [1984]. We practised this in our laboratory and observed specific and distinct tear ferning patterns for electrophoretic types 1 and 2 which Liotet et al. [1983] described as abnormal tear proteins modification found in patients who repeatedly and rapidly clog their hydrophilic lenses. In a general way, a study of tear ferning patterns can result in an appreciation of tear quality in contactology.
