Selective laser trabeculoplasty for elevated intraocular pressure following subtenon injection of triamcinolone acetonide.

Purpose: To report on the efficacy of selective laser trabeculoplasty (SLT) for elevated intraocular pressure (IOP) following subtenon injection of triamcinolone acetonide.

Method: SLT was performed on four of 148 eyes in which IOP was elevated after a subtenon injection of triamcinolone acetonide and could not be maintained within normal limits by conventional medications. Postoperative IOP and relative reduction of IOP were evaluated.

Results: IOP was reduced in three eyes to within the normal range without any medications six months after SLT alone, but trabeculotomy was performed on one eye. Percentage reduction in IOP after SLT was 21.6% at one month, 45.0% at three months, and 52.7% at nine months.

Conclusion: SLT may be effective in reducing elevated IOP following subtenon injection of triamcinolone acetonide and should be considered before glaucoma surgery.
