Two cases of suprachoroidal hemorrhage secondary to glaucoma surgery

摘要

We observed two cases of suprachoroidal hemorrhage secondary to glaucoma surgery. One was a 79-year-old male with exfoliation syndrome. Delayed suprachoroidal hemorrhage occurred 4 days after non-penetrating trabeculectomy. The other was a 75-year-old male with primary open-angle glaucoma. Expulsive suprachoroidal hemorrhage occurred during suture canalization. Both cases were treated by vitrectomy and transscleral drainage of hematoma later. Both cases had advanced age and aphakia in common. One case had systemic hypertension, history of vitrectomy and postoperative hypotony, and the other had high myopia as risk factors. Due precaution is necessary in performing glaucoma surgery in patients with such risk factors.
