Composite slit-lamp images of the left eye. a A localized encapsulated bleb with scar tissue in a ring of steel configuration on the superonasal conjunctiva at ten times magnification. Adjacent to the inferior part of the bleb, just above the site of the previous pterygium, is a nodular corneal degeneration and corneal scar. The diffuse conjunctival injection is also observed. b Deep anterior chamber and a sign of epitheliopathy (arrowheads) observed at 16 times magnification. c An examination with fluorescein staining was observed using blue light. The stain highlights the area of the dendritic ulcer and terminal bulbs (arrowheads). The Seidel test was negative over the bleb
