Yes, it is possible to develop glaucoma from trauma. Glaucoma refers to the imbalance of production and drainage of humor aqueous. Excessive production or bad drainage of humor aqueous would lead to increased intraocular pressure. Some trauma, blunt or penetrating, makes dysfunction of ciliary body or hematocele in eyes and lens would probably increase intraocular pressure and lead to glaucoma. Once got any trauma to eyes, you should go to hospital to have a check whether there is any debris or wounds in eyes. The earlier you get treatment for it, the better and faster you can get healed. If damages to nerve endings formed, therapy can only cure the wound but the damaged nerves are not curable. It means that once the vision impairment is established, there is no cure to restore it. So take actions now.
