Primary glaucoma, which is hereditary, and secondary glaucoma, which is the result of inflammation, a tumor, or an injury. Glaucoma usually first occurs in one eye, which is red, watering, blinking, and appears painful. A dilated pupil is unresponsive to light and the front of the eye has a whitish, almost blue, cloudiness. Vision loss and eventual blindness is the result, sometimes even with treatment (surgery or medication, depending on the case).
