My name is Dr. Beeran Meghpara, from Wills Eye Hospital in Philadelphia, Pennsylvania. I am an Assistant Professor of Ophthalmology as well at Sydney Kimmel Medical College at Thomas Jefferson University, also in Philadelphia, Pennsylvania. I would like to present a talk on "Infectious Conjunctivitis".
Now when I think about infectious conjunctivitis, I like to divide the disease into both, an acute and a chronic presentation, and I use a three-week duration as a delineation point between the two. When it comes to acute infectious conjunctivitis, typically there are two causes, bacterial and that would be either an acute bacterial infection, hyperacute, or neonatal, as well as viral, and then as far as chronic conjunctivitis goes, there are many causes of chronic conjunctivitis in general, but chronic infectious conjunctivitis, is typically either a Chlamydial infection, or a lid related infection known as blepharoconjunctivitis.
Bacterial conjunctivitis is actually not as common as one would think. It's actually an over treated entity. It is significantly less common than viral conjunctivitis in the adult population. The incidence of this is estimated to be about 135 in 10,000 in one reported study. Risk factors for developing a bacterial conjunctivitis include: disruption of the conjunctival epithelium, compromised tear production or a compromised ocular surface, abnormal lid positioning, trauma to the eye, and an overall immunosuppressed status.
