Device Gives Evidence of Shaken Baby

According to Thomas Lee, one of the study authors, “Traditional imaging is often used in documenting retinal damage in the eyes of children with SBS. However, it does not enable physicians to examine the surface of the retina in great detail. The handheld Spectral Domain Optical Coherence Tomography - or short SD-OCT - device enables us to examine the vitreoretinal interface and microarchitecture of the retina. Ophthalmologists can then differentiate the cause of the retinal damage and say with a high degree of confidence that it was caused by repetitive shaking and not a fall or other accident.”

Optical coherence tomography uses near-infrared and other long wavelength light to penetrate deep inside the eye. This enables a close-up look at tissues not visible with traditional camera technology.

Because retinal hemorrhage in the infant is one of the primary symptoms of SBS, ophthalmologists are often called upon to examine infants at risk and document their findings for possible submission to child protection authorities.

The study looked at the retinal findings of three consecutive cases of suspected SBS as they presented to the emergency room. All three patients underwent complete ocular examination, fundus photography with the RetCam and imaging with the handheld SD-OCT device. Of the six eyes examined, the SD-OCT device documented focal posterior vitreous separation in four of the eyes and multilayered retinoschisis in one eye. It also documented preretinal hemorrhages in five eyes. All patients had vitreoretinal abnormalities not detected on clinical examination (e.g. multilayered retinoschisis).
