To compare tear electrolytes and tear crystallization patterns in birds and reptiles, tears were sampled by Schirmer tear test from 10 animals each of Ara ararauna, Amazona aestiva, Tyto alba, Rupornis magnirostris, Chelonoidis carbonaria, and Caiman latirostris, and 5 of Caretta caretta. The aliquots were pooled to assess concentrations of total protein, chloride, phosphorus, iron, sodium, potassium, calcium, and urea. For the tear ferning test, samples of each species were observed under a…

Electrophoretic profiles and an evaluation of total protein, albumin, urea, glucose, and cholesterol concentrations in tears of semi-aquatic, terrestrial, and marine reptiles, birds, and mammals revealed similarities that are potentially derived from a homeostatic response to the environment.

The presence of oily droplet-like structures at the periphery of tear ferning suggests that camel tear film may have a higher quality and quantity of minerals and lubricants, which may help the animal to avoid eye dryness.

The preocular tear film plays a vital role in nourishing, lubricating and protecting the ocular surface and provides a basis for later consideration of clinical and surgical treatment of the dry eye.
Ocular Ferning Test – Effect of Temperature and Humidity on Tear Ferning Patterns

High humidity can modify and deteriorate the ferning patterns of tear fluid from subjects with normal tear function, and an rH not higher than 50% at a temperature range between 20 and 26°C produced ferning pattern without interstitial spaces which could be related to the best quality according to the system of Rolando.
