A localised area of corneal thinning adjacent to an area of conjunctival chemosis a week after a medial rectus resection, which pools fluorescein without true staining of an epithelial defect, is a dellen - a saucer of stromal dehydration caused by localised drying over the elevated conjunctiva. The initial treatment is intensive lubrication (and ointment or patching, with the swelling allowed to settle), which refills the area within hours to days. Steroids may delay healing, antibiotics are unnecessary without infection, and excision of the conjunctiva is not indicated.
