In this retrospective chart review, the authors evaluated the effectiveness of gonioscopy-assisted transluminal trabeculotomy (GATT) for steroid-induced glaucoma.

Study design

This retrospective case series included 13 patients who underwent GATT for steroid-induced glaucoma (SIG). Primary outcome measures included IOP, medication use and steroid use.

Outcomes

The authors observed a significant decrease in medication use after surgery. All eyes had an IOP of less than 15 mm Hg at the final study timepoint and were, on average, 2.3 fewer glaucoma medications. Approximately one-third of patients experienced postoperative transient hyphema. Interestingly, patients remained on their chronic baseline steroid use without resultant steroid response.

Limitations

This study was limited by its retrospective nature and lack of a control group. Furthermore, this study suffers from a limited number of patients, which is an unfortunate reality given the nature of steroid-induced glaucoma.

Clinical significance

Findings from this small case series suggest that GATT is an effective and safe technique to decrease IOP and medication burden in patients with steroid-induced glaucoma.
