When an eye sustains an injury there can be an acute increase in IOP due to damage to the angle structures, hyphema (blood in anterior chamber), inflammation, and other mechanisms. The more severe the trauma, the greater are the chances to develop glaucoma and other ocular complications. But IOP increase may also occur later in life due to damage of the trabecular meshwork. This form of glaucoma can occur even up to 10-20 years after injury. These are also considered secondary glaucoma cases.
It is recommended that any person who has sustained an injury to the eye should get him/herself evaluated for glaucoma, and maintain regular follow-up with an ophthalmologist.
