Could sinus congestion cause narrow angle closure glaucoma?

Sinus congestion: Will not cause angle glaucoma. In patients who have narrow anterior chamber angles (which would be diagnosed by an ophthalmologist), taking medications to treat a sinus infection could lead to an angle closure glaucoma attack. If you have narrow angles, you should avoid decongestants and anti-histamines until you are told by your ophthalmologist that it's ok to use them.
