Worm in the Eye:-A Contribution to Equine Surgery.

The research article discusses the experiences of a Civil Surgeon operating in India, treating horses for an intra-ocular parasite, or “worm in the eye”. The treatment of this equine condition isn’t widely written about, thus the author attempts to fill that gap by sharing surgical methods and observations.

Background of the Research

• The author’s experience as a Civil Surgeon in India forms the basis of this research. During their tenure, they have performed several surgeries to remove parasites known as “filaria papillosa” from the eyes of horses.
• Despite not being an equine surgery specialist, they feel it necessary to share the surgical procedure, as it seems underrepresented in authoritative veterinary literature.
• Although the Indian Medical Gazette, where this study was published, primarily focuses on human medicine and surgery, the correlation and relevance of animal pathology to human medicine cannot be undermined.

Purpose and Content of the Research

• The author aims to provide a first-hand account of his observations and surgical procedures, focusing on the removal of intra-ocular parasites from horses, which may provide useful insights for veterinarians.
• They do not delve into the natural history of the parasite, as it was already covered by Surgeon N.C. Macnamara in the Indian Annals of Medicine.
• The research does not provide a comprehensive view of the condition’s evolution from its inception to its final stage, as the author has not had the chance to observe a case from start to finish.

Observed Symptoms and Treatment

• According to their observations, the early signs of this condition don’t align with those described in existing literature. Rather than deep-seated ophthalmia typically associated with the parasite’s presence, the first observable symptom is the worm itself, seen swimming in the aqueous humour of the horse’s eye, without any apparent inflammation.
• The presence of the parasite typically does not attract attention until gradual corneal opacity commences.
• Based on descriptions from horse owners and other documented cases, if left untreated, the situation could eventually lead to inflammation, corneal ulceration, emptying of the eye contents along with the worm, or even permanent blindness.
