1. Intralesional triamcinolone acetonide injection versus incision and curettage for primary chalazia a prospective, randomized study Guy J. Ben Simon, Nachum Rosen, Mordechai Rosner, Abraham Spierer Goldschleger Eye Institute Am J Ophthalmol 2011; 151:714-718

2. Chalazia Plugged meibomian gland Chronic lipogranulomatous inflammation Local eye symptoms: irritation and inflammation Cosmetic disfigurement Larger lesions can induce mechanical ptosis corneal astigmatism Self limited in 25-50%

3. Treatment modalities Eyelid hygiene with warm compresses Antibiotic / steroid ophthalmic ointment Systemic tetracycline chronic blepharitis acne rosacea Surgical treatments steroids injections CO 2 laser excision and curettage total excision BTX-A

4. Steroid injection Intralesional or sub-cutaneously Reported success and resolution in 50-95% Simple and effective treatment serious adverse effects

6. Purpose To evaluate the safety and efficacy of intralesional triamcinolone acetonide (TA) injection in primary and recurrent chalazia 147 patients with primary or recurrent chalazia (155 cases)

7. Results Most of the patients received 1-2 injections Average time to resolution 2.5 weeks Patients who failed to respond 1-2 TA inj. more likely to result in failure to respond to further injections or in surgical excision Patients with blepharitis required on average more injections to resolution 2±1.3 vs. 1.4±1

8. Results

9. Conclusions Intralesional TA effective in lesion regression Chalazia that fail to respond to 2 or 3 injections most likely will necessitate surgical excision Should be considered as a first treatment in cases where diagnosis is straightforward
