Plain-English summary
A 10-year-old male neutered Rhodesian ridgeback cross was brought in because his third eyelid was sticking out abnormally while he was chewing. After thorough examinations and tests, including brain scans and fluid analysis, no clear cause was found, but the vet suspected a rare condition called trigemino-abducens synkinesis, which affects the nerves controlling eye movement. Since this is the first reported case in dogs, the exact cause remains unclear. The dog did not show any other concerning symptoms, and the condition may not require specific treatment unless it worsens.

Abstract
A ten-year-old male neutered Rhodesian ridgeback cross dog was presented for the investigation of abnormal bilateral protrusion of the third eyelid when chewing. Physical, ophthalmological, and neurological examinations were unremarkable. Thoracic radiographs, abdominal ultrasound, and magnetic resonance of the brain and orbits failed to reveal any abnormalities. Cerebrospinal fluid analysis revealed elevated protein, but the nucleated cell count was normal. trigemino-abducens synkinesis was presumptively diagnosed. Aetiopathogenesis of this condition is discussed. To the authors' knowledge, this is the first report of presumed trigemino-abducens synkinesis in a dog.
