Traumatic injury of the eye and treatment of eye injuries may lead to glaucoma. Both blunt force trauma and penetrating ocular trauma may damage structures that are critical for proper regulation of intraocular fluid flow and intraocular pressure. As well, bleeding and inflammation caused by trauma may result in elevated intraocular pressure. Glaucoma is most likely to develop within months of a traumatic injury, but may also occur many years later. Interestingly, there is a greater likelihood of glaucoma in the seemingly unaffected fellow-eye of patients with traumatic glaucoma in one eye.
