Original publication title: Contrast-enhanced ultrasonography in the differentiation of retinal detachment and vitreous membrane in dogs and cats.
Plain-English summary
A study looked at how well contrast-enhanced ultrasonography (CEU) can help veterinarians tell the difference between retinal detachment and vitreous membranes in dogs and cats. In 22 eyes examined, CEU was found to be 100% accurate in identifying retinal detachment, which can cause serious vision problems. While traditional ultrasound methods had some success, they were less reliable due to eye movement. This means that CEU could be a valuable tool for vets when diagnosing eye issues in pets, helping to ensure they get the right treatment quickly.

Abstract
OBJECTIVES: To evaluate contrast-enhanced ultrasonography (CEU) and colour Doppler imaging (CDI) for detection of persistent vascularisation in retinal detachment. METHODS: In 22 eyes, retinal detachment (n=13) and vitreous membranes (n=9) were confirmed by ophthalmological examination, during cataract surgery, by histopathology or after vitreoretinal surgery. Tentative diagnosis of retinal detachment or vitreous membrane was made using grey-scale B-mode ultrasonography. Assessment of retinal detachment was based on the presence or absence of vascularisation in the membranous structure using CDI and CEU. RESULTS: Sensitivity, specificity, positive-predictive value and negative-predictive value of grey-scale ultrasonography in differentiating retinal detachment from vitreous membrane were 92·3%, 66·6%, 80% and 85·7%. In 91% of eyes, colour Doppler assessment was unsuccessful due to the movement of the eye. Persistent vascularisation was demonstrated in all cases of retinal detachments with CEU. CEU was 100% accurate for detection and differentiation between retinal detachment and vitreous membrane. CLINICAL SIGNIFICANCE: CEU is a useful clinical tool for the diagnosis of retinal detachment and vitreous membrane in dogs and cats.
