Plain-English summary
A 1.6-year-old female German Shepherd service dog was brought in with a bulging area in her right eye, which was diagnosed as a focal retinal detachment linked to optic nerve colobomas (a defect in the optic nerve). After thorough imaging, the vet used a laser treatment to target the affected area. Three months later, the dog's condition showed improvement, and over the next couple of years, the retinal detachment completely resolved. The laser treatment was effective in managing the issue and preventing further complications.

Abstract
PURPOSE: To describe the ophthalmoscopic, in-vivo imaging, fluorescein angiography, and therapeutic photocoagulation outcome in a case of bilateral optic nerve colobomas associated with focal unilateral retinal detachment in a dog. METHODS: Pretraining eye examination of a 1.6-year-old female German shepherd service dog showed a focal juxta-papillary bullous retinal separation in the right eye. In vivo imaging and angiography were performed under general anesthesia using optical coherence tomography. Nonoverlapping diode laser burns were applied through an operating microscope adapter to selected areas along the leading margins of the detachment. RESULTS: The funduscopic examination and in-vivo imaging revealed bilateral optic nerve colobomas associated with a focal bullous detachment in the right eye. Fluorescein angiography showed absence of blood vessel leakage and absence of staining inside of the retinal elevation. Photocoagulation induced immediate changes in retinal layer reflectivity. Three months post-photocoagulation, the retinal detachment had improved and scarring of the burns was visible. One and two years post-procedure, the retinal detachment resolved. CONCLUSIONS: Optical coherence tomography (OCT) imaging provides a detailed analysis of the retinal abnormalities associated with the clinical lesion. Laser retinopexy is a valid therapeutic option to limit the extension of the detachment.
