Intralesional triamcinolone acetonide injection for chalazion.

The aim of the study was to evaluate the efficacy of intralesional triamcinolone acetonide injection in primary and recurrent chalazion. The study included 30 patients with primary and recurrent chalazion (37 cases) and 24 patients as a control group. Patients with primary and recurrent chalazion received intralesional injection of 0.1 to 0.2 mL triamcinolone acetonide (40 mg/mL). Control group received intralesional injection of 0.1 to 0.2 mL 0.9% NaCl. Data on the lesion size, including digital color photography, lesion regression or recurrence, and complete ophthalmic examination were recorded at the time of injection and after a week or two until resolution or surgical excision. Success was defined as at least 80% decrease in size with no recurrence. Resolution of the lesion was found in 35 cases after one or two injections, with a mean time to resolution of 15.27 +/- 6.12 days. Subcutaneous injection of the steroid triamcinolone acetonide in primary and recurrent chalazion appears to be a simple and efficacious therapeutic option for chalazion.
