You have not specified your age. Rise in pressure is one of the important sign of glaucoma
, ocular hypertension
, however in your case where there is history of some kind of injury which has not been clearly specified. In cases of head injury
or orbital haemorrhage there are some mechanisms by which the intraocular pressure
may rise. I suggest a complete work up of the eye by an ophthalmologist including visual fields. Single readings of increased pressure in the eye are not conclusive , the measurements should be repeated.
