Die chirurgische Behandlung von Augenkrankheiten beim Pferd

Surgical techniques in equine ophthalmology – A literature review - The objective of the presented study is to provide a comprehensive review of surgical intervention techniques and their results in the treatment of equine ophthalmologic disorders. The study surveys English, German and, to a limited degree, French literature beginning in the middle of the 19th century till today, including books, journal articles, conference proceedings and theses in the field of veterinary surgery, ophthalmology and equine diseases. Data was collected by screening of titles, keywords and bibliography of available literature and by using computer databases such as Vet-CD and Medline. Copies of the cited literature were obtained from the libraries of the Veterinary faculties in Munich, Hanover and London, the central library of the Ludwigs-Maximilians-University in Munich and the Bavarian library in Munich (Bayerische Staatsbibliothek). The chapter plan follows the anatomy of the eye and each chapter is subdivided into treatments of specific disorders. In addition chapter 1. eyelids, 3.1. conjunctiva, 3.2. third eyelid and 4. cornea include sections about specific operations performed on these structures. The horse was in the centre of surgical and ophthalmologic veterinary research and clinical work at the end of the 19th and the beginning of the 20th century - as it is reflected by the number of publications in these fields. Over the following years interest in equine ophthalmology lessened and it took till the last quarter of the 20th century to become an issue of interest again. In the meanwhile veterinary ophthalmology concentrated on small animals, especially the dog. Aetiopathogenesis and treatment of ophthalmologic disorders in the horse were hardly investigated and the specific anatomy and physiology of the equine eye were not considered to be of clinical interest. At the beginning of the 20th century reports about surgical treatment of equine ophthalmologic disorders are characterised by high case numbers, but lack statistical analysis of the data and many have in fact almost “anecdotal” form. Recent research follows today´s scientific standard methods and comprises case reports, retrospective and, to a lesser degree, prospective studies. Case numbers in this field of research are still low and comparison of different treatment methods is difficult due to the variety of disorders presented and the difference in study design. Some publications are missing out on important parameters, such as the quality of eye sight achieved after surgery; others use subjective judgement, but do not perform objective evaluation of certain parameters. There is also an obvious discrepancy between clinical prevalence of a disorder and the number of case reports dealing with it, e.g. corneal laceration, glaucoma. Some surgical techniques developed for small animals can be applied to the equine eye. However, this is not possible for all methods and the techniques may require at least species specific modifications. There are controversial discussions among the specialists in the field of equine ophthalmology with regards to indication of surgery and surgical technique, even down to the question which suture material is best. Today´s surgical techniques in equine ophthalmology seem to be far away from standardisation. More prospective and well-designed studies are desirable to provide comparable data for the different techniques in the future.
