The course and outcome of a disease process is dependent upon factors such as the disease-causing agent and its cell tropism, defense mechanisms of the host, genetic resistance of the species or breed affected, as well as the age, nutritional status and hormonal levels of the affected animal. When haematology, clinical biochemistry and cytology test results are combined with other laboratory procedures, complete physical examination and also with the history of the patient, a veterinarian is well armed to arrive at a definitive diagnosis, make a certain prognosis (good, poor or guarded) and can also make a concluding statement on the efficacy of the instituted therapy. In clinical biochemistry, demonstration of specific enzyme activity and concentration of analytes in serum/plasma facilitates the disease diagnosis. Also, evaluation of haematology, clinical biochemistry and diagnostic cytology tests can help establish the presence or absence of diseases of internal organs, and by serial performance of these tests, may help to determine whether a disease process remains static, progressive or regressive. This review therefore provides the haematological, serum biochemical and cytological characteristics of diseases caused by the main bacteria, viruses, fungi, protozoa, helminths, arthropods, nutritional deficiencies, endocrine disturbances, neoplasm, allergy, toxins (phytoxins and zootoxins) and inorganic poisons in horses.

“…Detection and assessment of ocular abnormalities during investigation of horses with systemic disease may provide valuable information on the differential diagnoses, treatment options, and prognosis of systemic disorders. Furthermore, timely recognition of ocular manifestations of systemic diseases will permit targeted ophthalmic treatment with potential benefits to limiting ocular pathology and vision loss . Unfortunately, ocular examination is nowadays greatly underused in the diagnosis of systemic diseases in the horse …”

Objective To describe ocular findings associated with Rhodococcus equi bronchopneumonia in foals, and to determine whether severity of the ocular lesions is related with outcome. Animals studied Foals diagnosed with R equi infection at the VTH‐UAB from January 2002 to December 2017. Procedure Rhodococcus equi infection was diagnosed by means of clinical signs, radiographic/ultrasonographic findings, and/or positive culture. In all the foals, a complete ophthalmic examination by a boarded ophthalmologist was performed and ocular signs were recorded and graded (0‐4). Results Thirty‐nine foals were included in the study, from which 12 showed signs of bilateral anterior uveitis (30.8%). Among these, three foals were classified as mildly uveitis‐affected (MUA:7.7%) and nine as severely uveitis‐affected (SUA:23.1%). Five SUA foals showed green aqueous flare (5/9;55.5%). Despite the systemic treatment, 9/39 sick foals died (23.1%), the fatality rate being different between groups: SUA (4/9;44.4%), MUA (0/3; 0%) and nonuveitis‐affected foals (5/27;18.5%). Among SUA foals, only one with green aqueous flare died (1/5;20%). Conclusion Bilateral anterior uveitis is highly prevalent in foals with R equi pneumonia (30.8%). The severity of anterior uveitis might be considered a nonsurvival prognostic factor and, until proven otherwise, green aqueous flare could be taken as a strongly suggestive ocular sign of the disease. Findings of this study remark the clinical relevance of performing a complete ophthalmic examination in sick foals, in order to help in the diagnosis and prognosis of uveal diseases, as well as to guaranteeing visual soundness.

Pudiendo tener diversas etiologías etiologías, que comprometen la calidad de la visión dependiendo del grado de la afección y del compromiso de las estructuras oculares afectadas (CUNHA et al 2015).…”

We report a case of an Argentine castrated male horse, about 8 years of age, which was attended by the outpatient clinic of the Medical-Surgical Clinic of Large Animals of the Faculty of Veterinary Medicine and Zootechnics of the University of Cordoba. The anamnesis indicates that the horse was in field work in a wooded land, which presented the next day of work increase in the production of tears and edema in the eyelids of the right eye, which was treated with eye drops antibiotic for 3 days. Fifteen days after the treatment was applied, the horse managers did not notice improvement, so they requested Veterinary Medical help. In the clinical evaluation of the animal, epifhora with purulent secretion, chemosis, conjunctivitis and edema with marked lesion of the corneal epithelium were found in the right eye. Special tests such as the Schrimer test were performed, with marked increase in lacrimal secretion; Subsequently the Fluorescein Sodium test was performed, evidencing the marked ulceration of the cornea. In definitive diagnosis, based on the special ophthalmic examination and the tests performed was of corneal ulcer.
