Abstract
Thelaziasis, caused by Thelazia spp., is an important ocular
parasitic disease in cattle, often leading to conjunctivitis, epiphora, corneal
opacity, and visual impairment. The present clinical investigation was carried
out on a 5-year-old Jersey crossbred cow that was presented to the Veterinary
Clinical Complex, Veterinary College, Salem, with a history of conjunctivitis,
excessive lacrimation, corneal opacity, and frequent blinking of the left eye.
The case had previously been treated by a local veterinarian with ocular
antibiotic drops, which failed to resolve the condition. Clinical examination
of the affected eye revealed the presence of numerous worms exhibiting vigorous
wriggling movements. Under local anesthesia, the worms were manually removed
using forceps, sent to the parasitology laboratory for examination, and
identified as Thelazia rhodesii. Post-operative care, consisting of
topical antibiotics and systemic medications, led to an uneventful recovery.
This study highlights the clinical features, diagnostic approach, and effective
therapeutic management of bovine ocular thelaziasis, emphasizing the need for
timely intervention to prevent corneal damage and vision loss in affected
cattle.
