Corneal edema and keratitis following selective laser trabeculoplasty

PURPOSETo describe three cases of keratitis following Selective Laser Trabeculoplasty (SLT). OBSERVATIONSThree females with a history of glaucoma presented with corneal edema, keratitis (endothelial, epithelial) and decreased visual acuity shortly after SLT. There was variable resolution of symptoms after starting treatment with oral antiherpetics and topical steroids. CONCLUSIONS AND IMPORTANCEWith the increase in usage of SLT as a treatment for glaucoma and subsequent reports of keratitis, it is imperative for ophthalmic surgeons to be aware of herpes simplex as a possible risk factor. Prompt treatment with antivirals and steroids can potentially prevent scarring and permanent damage to the cornea.
