Your question became much more than just "help me find an opthamologist." But you're still not required to accept my answer unless it is helpful to you.
You didn't tell me that you were in Texas. You just said you wanted to find one. So, I sent a directory.
Here's the list for Texas:
Animal Eye Clinic 5820 W. Interstate 20 Highway Arlington, TX 76017(NNN) NNN-NNNN
Animal Ophthalmology Clinic 4444 Trinity Mills Suite 201 Dallas, TX 75287(NNN) NNN-NNNN
Gulf Coast Animal Eye ClinicXXXXX Houston, TX 77055(NNN) NNN-NNNN
Eye Care for Animals 900 Country Club Santa Teresa, NM 88008(NNN) NNN-NNNN
Marc Rainbow, DVM, MS, DACVO South Texas Veterinary Ophthalmology 503 E. Sonterra Blvd. San Antonio, TX 78258(NNN) NNN-NNNN
Nicholas J. Millichamp, BVetMed, PhD, MRCVS Joan Dziezyc, DVM SACS College of Veterinary Medicine Texas A&M College Station, TX 77843(NNN) NNN-NNNN
Central Texas Veterinary Ophthalmology, P.L.L.C. Nicholas J. Millichamp, BVetMed, PhD, MRCVS Joan Dziezyc, DVMXXXXX Austin, TX 78758(NNN) NNN-NNNN
Audrey Yu-Speight, DVM, MS, DACVO Veterinary Eye Centers, PLLC Austin, TX(NNN) NNN-NNNN
Many of these opthamologists come highly recommended.
At this point, I'm still not sure that you need one. But that is completely up to you.
