Efficacy of 0.2% povidone-iodine and 0.1% polyhexamethylene biguanide as preoperative antiseptics in equine ophthalmic procedures.

Objective: This retrospective study evaluates the efficacy of povidone-iodine (PI) and polyhexamethylene biguanide (PHMB) as preoperative antiseptics in equine ophthalmic procedures.

Animals Studied: Horses that underwent routine ophthalmic surgery and procedures.

Procedures: Data were collected retrospectively from the medical records of equine patients undergoing ophthalmic procedures.

Safety and accuracy of blind vs. ultrasound-guided dorsal retrobulbar nerve blocks in horses-A cadaveric study.

Objective: There is limited knowledge regarding the safety and accuracy of ultrasound-guided retrobulbar nerve blocks in horses. The aim of this study was to compare these parameters between blind and ultrasound-guided injection techniques for the dorsal retrobulbar nerve block in horses.

Methods: Equine cadaver heads were used to inject the retrobulbar space with contrast medium (CM).

[Availability of drugs for the treatment of cats with ocular diseases in Germany - Discrepancy between theory and reality].

Objective: Only a few ophthalmologics specifically approved for cats are available on the market leading to frequent use of drugs approved for humans. In Germany, the administration, dispense or prescription of pharmaceuticals is regulated by the pharmaceuticals law ('Arzneimittelgesetz' (AMG)) as well as the regulation concerning pharmacies in veterinary practice ('Verordnung über tierärztliche Hausapotheken' (TÄHAV)). The aim of this study was to collect data concerning the occurrence and frequency of feline eye diseases and to evaluate the frequency of the necessity for extra-label drug use.

Photodermatitis and ocular changes in nine horses after ingestion of wild parsnip (pastinaca sativa).

Background: Primary photosensitization rarely occurs in horses and can easily be misinterpreted. Descriptions of the disease in horses after ingestion of parsnip are lacking. The aim of this case series was to describe the dermatological and ocular changes due to photosensitization and to raise awareness of parsnip being a possible aetiologic agent.

[Evaluation of the applanation tonometer Tono-Pen Avia® Vet™ for the measurement of the canine and feline intraocular pressure].

Objective: Using tonometers, intraocular pressure (IOP) is merely measured indirectly leading to measurement inaccuracies. All available technical devices are designed for humans, hence a calibration via comparison to manometric measurements is necessary for their use in veterinary medicine. In this study, the applanation tonometer Tono-Pen Avia Vet™ (TPA) was to be calibrated for use in dogs and cats resulting in the calculation of a correction factor.
