AIM: To analyze the incidence rate and risk factors of secondary glaucoma after intravitreal injection of triamcinolone acetonide. METHODS: Two hundred and fifty-six cases with the indication of triamcinolone acetonide were treated with intravitreal injection of triamcinolone acetonide 4mg/0.1mL, and postoperative intraocular pressure changes were observed. Main indications included wet age-related macular degeneration, and macular edema disease caused by other reasons, such as diabetic retinopathy, central retinal vein occlusion, branch retinal vein occlusion, retinal periphlebitis. RESULTS: Among the 256 patients (256 eyes) who were followed up for at least 3 months, secondary glaucoma occurred in 56 eyes, and the incidence rate was 21.9%. CONCLUSION: Secondary glaucoma does seem to be not correlated with age, sex, blood pressure, diabetes, and different indications of drug infusion into vitreous cavity, whether the patient underwent preoperative cataract surgery, photodynamic therapy or vitrectomy. The history of glaucoma before drug injection and basic intraocular pressure above 19mmHg are significant risk factors for secondary glaucoma. LA: Chinese
