Extirpation of eyeball due to myiasis induced wound in a jersey cross bred heifer calf

Abstract

Myiasis wound is a parasitic infestation of the tissues of a living vertebrate animal by the larvae of flies, which grow inside the host while feeding on its dead or living tissue, causing varying degrees of traumatic injury. This condition is particularly common during the rainy and winter seasons. In the present study, an 8-month-old Jersey crossbred heifer calf was presented with a history of bloody discharge and swelling of the right eyelid for the past 7 days. Upon examination, it was found that the calf’s right eye was infested with maggots, and the eye structures had been completely consumed by the larvae. Based on the clinical findings, it was decided to perform complete extirpation of the affected eyeball. This was done using nerve block techniques and available surgical instruments under field conditions. The calf recovered well post-surgery, and appropriate follow-up care was provided.
