Surgical Management of Glaucoma Secondary to Bilateral Acute Iris Transillumination: A Role for Gonioscopy-assisted Transluminal Trabeculotomy.

PURPOSE: We report a case of bilateral acute iris transillumination (BAIT) in a young woman associated with ocular hypertension which eventually progressed to glaucoma that was treated with gonioscopy-assisted transluminal trabeculectomy (GATT).

CASE REPORT: A 37-year-old otherwise healthy female presented with intermittently red and inflamed eyes and blurred vision. She was treated with oral moxifloxacin months prior to presentation. Iris transillumination defects, a pigmented anterior chamber reaction, the absence of keratic precipitates, and a history of upper respiratory infection treated with an oral fluoroquinolone prompted the diagnosis of BAIT. Intraocular pressure (IOP) remained uncontrolled on multiple glaucoma medications. Following the development of new visual field defects, indicating progression to glaucoma, GATT with cataract extraction was performed.

CONCLUSION

Although surgical intervention is rare with BAIT, our case demonstrates that GATT may be used effectively in those patients needing better IOP control before considering incisional glaucoma surgery.
