Glaucoma is a condition that affects the eyes, specifically the optic nerve. It is more common in people with diabetes and elderly adults. There are two types of glaucoma: open-angle and closed-angle.
Closed-angle or angle-closure glaucoma occurs when there is a blockage in the anterior chamber of the eye, the space in front of the lens. Fluid within the eye gets trapped and pressure increases. This intraocular eye pressure can cause a headache with eye pain, blurry vision, nausea, and vomiting. Eye redness and eye pain can be severe.
Glaucoma requires an evaluation and treatment from a doctor, therefore, should not be treated at home. The doctor will measure your intraocular pressure and recommend medications. In some cases, surgery is necessary to relieve the pressure and restore vision.
Sinusitis or swelling of the sinuses may also cause headache with eye pain.
Sinuses are spaces in the skull located around the nose and eye areas. The sinuses help to drain fluid and provide structure to the skull without weighing it down. Within the sinuses are blood vessels and respiratory epithelium, which is responsible for mucus production and filtering particles when we breathe. Some areas also house smell receptors.
Usually, sinus infections are viral. Sometimes bacteria can also be responsible. When the pathogen enters the cells that line the sinuses, it can cause inflammation. As pressure builds up within the bony sinuses, it can cause a headache with eye pain.
