Conjunctival Pyogenic Granuloma after Sub-tenon's Block

초록

Purpose: We report a case of conjunctival pyogenic granuloma that developed after sub-Tenon's block at the inferotemporal conjunctival quadrant during cataract surgery. Case summary: A 74-year-old male patient with senile cataract, diabetic retinopathy and open-angle glaucoma, who was using a combination of timolol/tafluprost and brimonidine eyedrops, underwent uneventful cataract surgery after sub-Tenon's block at the inferotemporal conjunctival quadrant of his right eye. Moxifloxacin, 1% prednisolone acetate and 0.1% bromfenac sodium hydrate were administered daily for 1 month post-surgery, by which time a pink-colored, oval-shaped granulomatous mass had developed on the inferotemporal conjunctiva, at the site of the sub-Tenon's block. Dexamethasone and antibiotic combination eye drops were administered without resection of the mass, which had markedly regressed after 2 weeks and disappeared completely 6 weeks after treatment. Conclusions: Patients should be informed of the possibility of conjunctival pyogenic granuloma prior to cataract surgery using sub-Tenon's block, and it is important to carefully check the block site and compliance with eyedrops at follow-up visits. Conjunctival pyogenic granuloma can be successfully treated with topical steroids.
