Cataract surgery in pinnipeds is challenging due to small pupils unresponsive to standard dilating drops. A manual irrigation and aspiration technique successfully restored vision in a fur seal with cataracts.

Area of Science:

  • Veterinary Ophthalmology
  • Marine Mammal Medicine

Background:

  • Cataracts are prevalent in pinnipeds, complicating ocular examinations and surgical interventions.
  • Standard mydriatic agents (tropicamide, phenylephrine, atropine) are ineffective for dilating the constricted pupils of pinnipeds.

Observation:

  • Ocular examination and surgical access to the lens were severely limited by the small, non-dilating pupil in a fur seal.
  • A manual irrigation and aspiration technique was employed for cataract removal.

Findings:

  • Successful cataract removal using a manual irrigation and aspiration technique was achieved in a fur seal.
  • Vision was demonstrably restored following the surgical procedure.

Implications:

  • This manual technique offers a viable surgical approach for cataract treatment in pinnipeds.

  • Further research into effective pupil dilation methods for pinniped ophthalmology is warranted.
