Moxifloxacin-associated acute pigment dispersion and iris transillumination after phakic lens surgery
Abstract
Introduction: Acute pigment dispersion and elevated intraocular pressure (IOP) were found after phakic intraocular lens surgery where 0.5% moxifloxacin was used. While scattered reports can be found in the literature, to the authors' knowledge, this is the first time it has been linked to intracameral 0.5% moxifloxacin. Patient and Clinical Findings: A 23-year-old man experienced symptoms of unilateral eye pain, increased IOP, diffuse pigment dispersion, transillumination defects, and mydriasis after successful bilateral Starr Visian EVO implantable collamer lens implantation. Diagnosis, Intervention and Outcomes: Intracameral moxifloxacin (0.5%) was given at the time of the procedure and was suspected to be the cause of this patient's postoperative findings. These findings are consistent with iris toxicity associated with systemic moxifloxacin. Supportive care was given, however, the resulting pigment dispersion and mydriasis are permanent. Conclusions: Although generally safe for intracameral use, moxifloxacin has the potential to be toxic to the iris. Patients with phakia may be at higher risk of this toxicity, and lower concentrations of intracameral moxifloxacin should be considered in these patients.
