Shaken Baby Syndrome

The Shaken Baby Syndrome could be define as a group of signs and symptoms resulting from violent shaking and impacting the head of an infant or small child. Injury to the brain in SBS may include subdural hematoma, unilateral or bilateral over the cerebral convexities, or in the interhemispheric fissure. 
In addition to widespread retinal hemorrhages, ocular injury may include retinal detachment, vitreous hemorrhage, and optic nerve injury. Vision loss most commonly results from cortical injury or optic atrophy.

The US government estimates that about 30 children younger than one year of age per 100,000 are injured from AHT, resulting in at least 1200 seriously injured infants and at least 80 deaths each year.

How to perform a retinal examination

The application allows users to capture images of the optic disc of non-mydriatic eyes.  It can be used for Glaucoma screenings without dilation drops. Dilation drops will be required to increase field of view (FOV) to see more retinal structure that would include the observation of AMD and mild non-proliferative retinopathy.

Using the video function will capture maximum retinal structure regardless of dilation. The auto focus function is set for 1cm of distance from the pupil. If the lens is too far away, the results of the exam will not be in focus and the pupil will appear very small. An examination of a non-mydriatic pupil will result in the view of the optic disc and partial retinal structure around the disc. More structure can be seen with a mydriatic pupil. With the optic disc centered, the acquisition protocol would be to pan the retina, starting from the posterior pole and then moving to the upper, nasal, inferior, and nasal peripheral retina to the equator. This exam protocol encompasses the posterior pole, including the macula, optic disc, and peripheral retina.
