Abstract

Coursing is a canine sport discipline invented for sighthounds. The dogs chase the mechanically operated lure on an open area at the track that consists of straight lines as well as turns. Thus, the dogs must rely mainly on their sight in order to chase the lure and to compete.
Whippets are the most popular sighthound breed in Poland and more and more dogs practice lure coursing on professional level. Several ocular disorders are known or presumed to be inherited in Whippets, so we decided to check how often they occur amongst competing dogs and if they have any impact on the results during competitions.
Forty-five regularly competing Whippets underwent complete ophthalmic examination, including evaluation of menace response, pupillary light reflex and dazzle reflex, biomicroscopic examination conducted before and after dilating pupils with topical tropicamide and fundus examination with indirect ophthalmoscopy. Refractive state of each eye was assessed via streak retinoscopy.
Ocular abnormalities were identified in 24 dogs (53.3%). The most common finding was vitreous degeneration identified in 9 dogs (20%), five dogs presented multiple lesions. There were no statistically significant differences regarding sex, age, and ranking points between the dogs with and without lesions.
However, some of the identified lesions are likely to progress, so we postulate that the ophthalmological examination should receive more attention in sport Whippets, to check if it has any impact on competing dogs at more advanced age.

Abstract

The prevalence of vitamin D deficiency in the American and European population is estimated to be extremely high. Although fewer people today suff er from serious health problems related to calcium and phosphate metabolism resulting from vitamin D deficiency, there are more and more studies suggesting that calcitriol may play an important role in the pathogenesis of other diseases in virtually every body system. A growing body of research shows that through its ubiquitously expressed receptor, calcitriol displays potent anti-angiogenic an anti-inflammatory activity. Th is review summarizes recent discoveries regarding these non-classical eff ects of vitamin D and their clinical implications. Data collection focused on the prevention and treatment of ocular diseases as well as on the underlying mechanisms.
