To report keratitis after uneventful Selective Laser Trabeculoplasty (SLT).


4 cases with Primary Open Angle Glaucoma (POAG) presented with decreased vision and corneal stromal edema one day after uneventful SLT.


: Examination revealed localized or diffuse central corneal edema with haze and striae unassociated with rise of intraocular pressure within 24 hours of SLT. There were no untoward events during SLT, which was applied using standard parameters (100 spots) ranging in power from 80 to 1010 mJ. After starting topical steroid drops, within a few weeks there was clearing of edema but central anterior stromal haze in a nummular configuration persisted. Delayed corneal thinning with hyperopic shift and astigmatism developed.


These cases highlight rare instances of SLT induced keratits. Detailed study of such case is needed to understand pathogenesis.
