My friend who is in her early 30s was diagnosed with intraocular pressure. Could this be related to a severe concussion with subsequent unconsciousness she suffered 18 months ago. Her headache is on the same side of her head as where she hit it on a cupboard door and was knocked out in the incident. She woke up in the ED and didnt remember anything after hitting her head.
Hi, Welcome to Chat Doctor forum.  The causes of intro ocular pressure may be the glaucoma, ocular hypertension, blind less etc. It may not be related to the head injury, but as a secondary effect would have effect on the eye and cause ocular hypertension.  If there is no glaucoma, it may be a suggestion of developing glaucoma in 5 years.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to protect the eyes from glaucoma.  Wishing for a quick and complete recovery. Thank you
