Hypopyon following selective laser trabeculoplasty

PURPOSE: To report a hypopyon following selective laser trabeculoplasty (SLT). OBSERVATIONS: An 85-year-old woman with primary open-angle glaucoma underwent routine SLT. In the early post-procedural period, she presented with pain and decreased vision, and she was found to have hypopyon, trabeculitis, and corneal edema. The patient was treated with prednisolone acetate and empirically with valacyclovir due to the possibility of herpetic keratouveitis. Work-up for potential etiologies was unrevealing. Her symptoms resolved with treatment, and at eight months follow-up her visual acuity and intraocular pressure had stabilized to her baseline. CONCLUSIONS: Though safe, SLT may be associated with rare adverse events requiring intervention. Hypopyon following SLT is extremely rare, and investigation for causes unrelated to the history of SLT should be undertaken as appropriate. IMPORTANCE: To the best of our knowledge, this is the first report of a hypopyon following SLT in a patient with no history of inflammatory intra-ocular disease.
