Argon laser trabeculoplasty in triamcinolone acetonide induced ocular hypertension refractory to maximal medical treatment

Eur J Ophthalmol. 2006 Sep-Oct;16(5):756-7. doi: 10.1177/112067210601600516.

Abstract

Purpose: To report two cases of intraocular hypertension after intravitreal injection of triamcinolone acetonide (iTAA) that were refractory to maximal medical therapy and were successfully treated with argon laser trabeculoplasty (ALT).

Methods: Two patients with history of primary open angle glaucoma were treated with intravitreal injection of triamcinolone acetonide for chronic macular edema secondary to branch retinal vein occlusion. Both patients (Case 1 after 2 months and Case 2 after 5 days) developed intraocular hypertension that did not respond to maximal medical therapy. Despite medical therapy, intraocular pressure (IOP) was 45 mmHg in Case 1 and between 34 and 37 mmHg in Case 2. ALT was performed in the inferior 180 degrees angle using the following parameters: 50 microm size, 700 mW, 0.50 sec, 100 spots.

Results: In both patients IOP returned to normal level a few days after ALT.

Conclusions: ALT seems to be effective at reducing IOP in patients with intraocular hypertension secondary to iTAA that does not respond to maximal medical treatment.
