Enucleation in equids with and without the use of an orbital suture meshwork implant: a retrospective study of 37 cases.
Lyon/Bern – mechentel news – This retrospective study on 37 horses was conducted to assess long-term complications, scarring, cosmetic appearance and owner satisfaction of horses that underwent transpalpebral enucleation with (n=26) or without (n=11) non-absorbable sutured meshwork prosthesis between 2006 and 2013. Postoperative complications related to the surgery...

Dogs Evaluate Threatening Facial Expressions by Their Biological Validity – Evidence from Gazing Patterns.
Helsinki – mechentel news – Appropriate response to companions‘ emotional signals is important for all social creatures. The emotional expressions of humans and non-human animals have analogies in their form and function, suggesting shared evolutionary roots, but very little is known about how animals other than primates view and process facial expressions. In primates, threat-related facial expressions evoke exceptional viewing patterns compared with neutral or positive stimuli....
Aging Dogs Manifest Myopia as Measured by Autorefractor.
St. Joseph – mechentel news – Dogs, like humans, experience eye changes with aging: hardening and clouding of the lens and accumulated oxidative damage from UV sunlight. It has been debated whether such changes could be affecting the visual function of dogs. The objective of this study was to determine if autorefractometry could be used to measure visual function in dogs. Nine Beagle dogs (ages 1 to 14 years) were examined by a veterinary ophthalmologist and their eyes determined to...
Measurement of tear production and intraocular pressure in ducks and geese.
Teheran – mechentel news – The purpose of this study was to establish a reference value of tear production and intraocular pressure in clinically normal ducks and geese.
The study population consisted of forty-eight ducks (24 males and 24 females) and fifty-two geese (26 males and 26 females). Birds were gently physically restrained in dorsoventral position without any pressure to the head and neck. Tear secretion and intraocular pressure were measured using 5-mm-wide Schirmer tear...
