  • The visual impairment represents a combination of the morphologic changes in the eye, retinal dysfunction, and cortical functioning. (medscape.com)
  • This test investigates if the dog carries the mutation in the BEST1 gene that has been described as cause for the disease Canine Multifocal Retinopathy 1 (cmr1) in mastiff-related breeds.The disease is inherited as an autosomal recessive characteristic and only occurs if the dog carries two mutated alleles.

  • In some cases, these treatments may just help to prevent additional disease progression or vision loss. (healthline.com)
  • The developments in high-resolution multimodal retinal imaging have also transformed our ability to make accurate and more timely diagnoses and more sensitive quantitative assessment of disease progression, and allowed the design of optimised clinical trial endpoints for novel therapeutic interventions.
