Dellen associated with filtering blebs. 1983

H K Soong, and H A Quigley

Dellen may occur in the corneas of eyes with filtering blebs. Nine cases of such dellen were encountered in a series of 97 consecutive trabeculectomies. In two such patients, the dell progressed to a deep corneal ulcer, although in most cases it healed uneventfully with minor changes in therapy. The use of topical prednisolone acetate during the postoperative period may also contribute to dellen formation by inhibiting corneal epithelial wound healing. However, the most important factor predisposing to dellen formation was poor tear-film integrity adjacent to the bleb. The secretion of the aqueous tears seemed to have little or no effect on dellen formation. Almost all dellen occurred in eyes with large filtering blebs.

D005901	Glaucoma	An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.
