ABSTRACT
The aim of this study was to determine the prevalence and type of ophthalmic diseases among horse populations in the suburbian riding clubs of Tehran. Ophthalmologic examinations were performed in 901 horses and ocular lesions were diagnosed in 40 [4.4%] animals. In the 54 eyes of these horses that had ocular defects, 103 ocular abnormalities were detected. Of those horses affected, 65% showed abnormalities in one eye and 35% had abnormalities in both eyes. Various sequelae to ocular trauma and periodic ophthalmia were the most common and recognizable causes, which comprised 25% and 15% of horses with ocular defects, respectively

An eleven month old filly was referred to the Research and Teaching Hospital of the Faculty of Veterinary Medicine at the University of Tehran. The animal presented a three-week history of diarrhea and previous treatments had failed to effect a recovery. Based on the history, clinical findings and results of laboratory investigations, it was assumed that a gastrointestinal disorder was affecting the filly. After the exclusion of other possible etiologies, Brachyspira spp. became the most likely causative agent. Despite supportive therapy in hospital, the clinical condition of the filly deteriorated over the course of eleven days and the animal died of inanition and consequent multiple organ dysfunctions. Subsequent pathological investigation confirmed a Brachyspira spp. infection of the gastrointestinal tract. This report is believed to be the first equine case of Brachyspira-associated gastroenteritis
