A 30-YEAR-OLD man with unilateral angle-recession glaucoma in the right eye and controlled intraocular pressure (<17 mmHg) 2 months after his last visit had an intraocular pressure of 50 mmHg in the right eye. Before the intraocular pressure increase, standard achromatic automated perimetry results were normal (Figure 1), but scanning laser polarimetry (Figure 2)and frequency-doubling perimetry (Figure 3) results were abnormal. After the intraocular pressure increase, there were changes in scanning laser polarimetry results and progression of visual field defects at standard a chromatic automated perimetry. An increase in superior and inferior nerve fiber loss was observed with scanning laser polarimetry, which is compatible with the changes in the visual field. Test results in the left eye remained normal.
