Abstract

PURPOSE
To report a case of hyphema after selective laser trabeculoplasty (SLT) in a patient with pseudoexfoliative glaucoma.
CASE SUMMARY
A 77-year-old female was referred for elevation of intraocular pressure (IOP). Previously, she had been diagnosed with pseudoexfoliative glaucoma in the right eye and was using topical IOP-lowering agents. The best corrected visual acuity was 20/100 in the right eye and 20/40 in the left eye. IOP, measured with Goldmann applanation tonometer, was 32 mm Hg in the right eye and 20 mm Hg in the left eye. Gonioscopy revealed open-angle glaucoma with +2 trabecular meshwork pigmentation but without peripheral anterior synechiae or neovascularization. SLT was performed in the right eye. Two days later, the patient had sudden onset of blurred vision and pain in the right eye. Visual acuity was limited to light perception, and IOP was 34 mm Hg in the right eye. Slit-lamp examination revealed 1.1 mm hyphema with 4+ red blood cell count in the anterior chamber. Three weeks after the SLT, hyphema in the right eye disappeared, but IOP was measured to be 42 mm Hg. The patient underwent trabeculectomy in the right eye.
CONCLUSIONS
SLT is an effective means of lowering IOP with low risk of complications. However, hyphema can rarely occur after SLT and can affect the outcome of the treatment.
