Purpose: To report a case that demonstrates the use of B-scan ultrasonography complemented with color Doppler imaging in the successful diagnosis of retinal detachment in a dense asteroid hyalosis presentation.

Methods: Retrospective case report.

Case Report: A 65-year-old Asian female, complained of decreased right eye vision 25 days prior to examination. Fundoscopy showed dense asteroid hyalosis, hindering an accurate assessment of the retinal status 10 MHz. B-scan ultrasonography (Aviso, Quantel®) at 10 MHz showed a bright, continuous, highly reflective membrane at A-scan. Kinetic evaluation revealed restricted movement, extending from the optic disc to the periphery at meridians 1 to 8 clock-hours. The main diagnostic hypothesis was superior nasal extended to inferior temporal retinal detachment. Differential diagnosis included a localized posterior vitreous detachment with a thickened hyaloid. A 15-MHz color Doppler ultrasound transducer (Esaote Mylab 60) detected arterial blood flow in the membrane identified during the B-scan ultrasound, confirming the diagnosis of localized retinal detachment.

Conclusion: Ocular ultrasound and a complementary evaluation with color Doppler can be useful in unusual presentations of asteroid hyalosis.
