How many Veterinary ophthalmologists are there in US?

As of my knowledge cutoff in May 2022, there are approximately 500 board-certified veterinary ophthalmologists in the United States. These specialists have undergone extensive training and are certified by the American College of Veterinary Ophthalmologists (ACVO).

It is important to note that this number may change over time as new ophthalmologists complete their training and become certified, or as some currently practicing ophthalmologists retire or leave the field. For the most up-to-date information, you may want to refer to the ACVO's official website or contact the organization directly.
