Primary Creeping Angle-Closure Glaucoma

IN some eyes with shallow anterior chambers and narrow angles, an insidious and usually symptomless angle-closure occurs until the unsuspecting patient suddenly becomes aware of reduced vision. So stealthy is the theft of vision that blindness may occur in one eye before the patient realizes that anything is wrong. The disease may closely resemble chronic simple glaucoma with narrow angles but the outflow impairment is different.
