The Centers for Disease Control estimates that around 2.8 million people in the United States suffer from a traumatic brain injury (TBI) every year, and vision can be affected.  Concussions are a type of TBI.

The rate of childhood TBI visits to the emergency department more than doubled between 2001 and 2009, making children more likely than any other group to go to the ER with concussion symptoms.

Let’s dive into one of the most common eye conditions we treat: hordeola (commonly known as “styes”) and chalazia.

Hordeola (or singular hordeolum), are infectious abscesses of the glands that line the eyelids. Bacteria that are naturally occurring on the eyelids and eyelashes can make their way into the gland and form what is essentially a pimple in the eyelid. If it goes untreated, hordeola can (rarely) lead to spreading of the infection throughout the eyelid (preseptal cellulitis) or even start to invade...
