Acute glaucoma secondary to angle obstruction by triamcinolone crystals.

PURPOSE: To present a case of acute glaucoma secondary to massive transit of triamcinolone acetonide into the anterior chamber in a pseudophakic, vitrectomized eye following intravitreal injection for treatment of cystoid macular edema. SETTING: Manchester Royal Eye Hospital. METHOD: Case study. CONCLUSION: In vitrectomized eyes with open posterior capsule receiving high dose intravitreal triamcinolone, it is prudent to perform pressure check within a week of injection.
