Definition
Trauma can cause IOP elevation by inflammation, red blood cells (hyphema), or direct injury of the trabecular meshwork or the lens with lens (sub)luxation (De Leon-Ortega and Girkin 2002). Each of these or a combination of them can be the reason for traumatic glaucoma. Normally, the IOP elevation is of short duration but could be prolonged with a risk of nerve damage (Herschler and Cobo 1982).
Etiology
Ocular trauma is the reason for the development of traumatic glaucoma.
Clinical Presentation
Hyphema (Fig. 1) often with rebleeding during the first week may cause IOP elevation by obstruction of the trabecular meshwork. The risk of elevated IOP increases by the amount of hyphema. On the other hand, a small hyphema can also cause a marked IOP raise, especially in an additionally and otherwise compromised angle (Schlote and Rohrbach 2005).
