EKC adenovirus causing viral conjunctivitis (Video)

This video shows an eye with EKC viral conjunctivitis, caused by the adenovirus. Here you can see numerous subepithelial infiltrates. The easiest way to visualize these is by aiming your slit-lamp light so it comes in from the side and diffusely illuminates the corneal surface.

This cornea is suffering from EKC (epidemic keratoconjunctivitis). The adenovirus is one of the leading causes of the common cold and when it hits the eye, can cause both a conjuncitivis and a keratitis (corneal inflammation). This serotype of virus is very contageous and as eye doctors, we are always worried about catching this as the stromal scars can incapacitate vision for months.

corneal EKC
This photo shows an eye suffering from EKC (Epidemic Keratoconjunctivitis). If you look closely at the cornea, you can see subtle white infiltrates overlying the black pupil.
Epidemic keratoconjunctivitis
This photograph of the cornea shows the classic subepithelial infiltrates of EKC. The best way to see these subtle spots is to widen your slitbeam and view the cornea from an extream angle.
EKC eye
This slit-lamp photo was taken from an eye suffering from EKC (Epidemic Kerato conjunctivitis). The infiltrates seen are subepithelial, which you can see from this corneal cross-section as being on the surface.
