At present, the eye refractive error was -6.00 diopters.The right and left intraocular pressure was 50 mm Hg OD and 45 mmHg OS respectively. Slit examination revealed conjunctival injection, corneal edemaand shallow anterior chambers. The patient had a history of taking topiramate tablets one week earlier. Topiramate was discontinued and she was treated with anti-glaucoma and cycloplegic drugs. Intraocular pressure and refractive errors were normalized within 3 days and 2 weeks, respectively. Conclusion: Topiramate can cause acute angle-closure glaucoma and myopia even at low doses or for a short period usage.
