Use of orbital implants after enucleation in dogs, horses, and cats: 161 cases (1980-1990).

The research article discusses a study on the use of orbital implants in dogs, horses, and cats following eye enucleation, with the data indicating that this procedure is safe and inexpensive while improving the cosmetic appearance of the animals.

Study Population and Methods

• The study included 109 dogs, 29 horses, and 23 cats who underwent eye enucleations during which either silicone or mesh implants were placed in the orbital socket.
• The follow-up period for these animals ranged from a few weeks to several years. The average follow-up times were 2.4 years for dogs, 3.4 years for horses, and 1.5 years for cats.

Results of the Study

• Implants failed in 1.04% of dogs, 10.3% of horses, and 16.7% of cats. Failures were attributed to various causes across the species.
• Cats appeared to have a higher frequency of late extrusion, or expulsion of the implant, compared to dogs and horses.

Conclusion of the Study

• The researchers concluded that the implantation of an orbital prosthesis after eye enucleation was generally safe and inexpensive, and significantly improved the cosmetic appearance of the animals.
• Even though a small proportion of animals experienced implant failure, it’s clear from the data that the procedure has a high success rate across the different species studied.
