BACKGROUND: We report a patient who was diagnosed as having steroid-induced glaucoma after radial keratotomy (RK) and who suffered from severe visual field defect.CASE: A 29-year-old man underwent RK for both eyes. After the operation, he was treated for six months with topical medication including 0.1% and 0.01% betamethasone without an intraocular pressure (IOP) measurement. When he consulted an ophthalmologist, his IOP was 43 mmHg in the right eye and 51 mmHg in the left eye. At our initial examination, his IOP was 8 mmHg in the right eye and 10 mmHg in the left eye. He was taking 750 mg acetazolamide peroral, 0.5% timolol maleate, and latanoprost eyedrops. There were 16 RK incisions on the cornea and we found severe glaucomatous visual field loss. Finally we performed trabeculotomy in both eyes for IOP control with conservative therapy.CONCLUSION: As keratorefractive surgery becomes popular, we must be alert for problems, such as steroid-induced glaucoma, and the change in refraction following the change in IOP.
