The face of a patient with acute glaucoma, showing a severely inflamed right eye (on left). Glaucoma results from an increase in the intraocular pressure, the pressure within the eye. Primary glaucoma may arise in the absence of any other eye disease; secondary glaucoma is due to pre-existing eye disease disrupting the normal circulation of aqueous humour within the eye. Primary glaucoma occurs increasingly with age & is an important cause of blindness. Treatment is directed at reducing the intraocular pressure, by using drugs or ultimately surgery (trabeculectomy) to improve both the drainage & production of aqueous humour.
