Abstract Purpose:We report a case of corneal stromal opacity that rapidly progressed upon the use of brimonidine tartrate ophthalmic solution for the treatment of glaucoma. The symptom improved following discontinuation of the administration and the use of ocular steroid instillation.

Case:A 78-year-old female was diagnosed with primary open-angle glaucoma in both the eyes and was treated with tafluprost/timolol maleate solution in 2014. Due to the progression of visual field defect, brimonidine tartrate ophthalmic solution was additionally administered in February 2019. The right eye showed slight opacity with neovascular vessels at the cornea on the temporal peripheral area in November 2020. One month later, the corneal opacity with neovascular vessels progressed rapidly, approaching the central region of the cornea. After another month, the opacity further progressed, and the corrected visual acuity decreased to 0.3 in the right eye. Anterior segment optical coherence tomography showed high intensity region at the stroma of the cornea, which was consistent with the corneal opacity. We considered that the corneal opacity was caused by the use of brimonidine tartrate ophthalmic solution and discontinued its use. Instead, betamethasone phosphate sodium ophthalmic solution was administered in January 2021. After two weeks, the degree of corneal opacity decreased and the corrected visual acuity improved to 0.5, although the corneal opacity area did not change in the right eye. The degree of opacity gradually diminished, and the visual acuity improved to 0.6 at 2 months after the administration of betamethasone phosphate sodium ophthalmic solution.

Conclusion:If corneal opacity occurs following the administration of brimonidine tartrate ophthalmic solution, it is imperative to identify other causes promptly, discontinue the use of brimonidine tartrate ophthalmic solution, and perform topical steroid instillation.
