Whole-genome sequencing identifies missense mutation in GRM6 as the likely cause of congenital stationary night blindness in a Tennessee Walking Horse.

Background: The only known genetic cause of congenital stationary night blindness (CSNB) in horses is a 1378 bp insertion in TRPM1. However, an affected Tennessee Walking Horse was found to have no copies of this variant.

Objectives: To identify the genetic cause for CSNB in an affected Tennessee Walking Horse.

Corneal hypoesthesia, aqueous tear deficiency, and neurotrophic keratopathy following micropulse transscleral cyclophotocoagulation in dogs.

Objective: To describe ocular surface complications following micropulse transscleral cyclophotocoagulation (MP-TSCPC) in dogs.

Animals Studied: Eighteen dogs treated with MP-TSCPC at two institutions for glaucoma management.

Procedures: MP-TSCPC was applied to each eye (avoiding 3 and 9 o'clock positions) with 31.
