Scleral ectasia as a complication of deep sclerectomy.

Nonpenetrating deep sclerectomy is a filtration surgical technique to treat glaucoma. A 12-year-old girl presented with chronic arthritis complicated with glaucoma secondary to a chronic uveitis. A sclerectomy without a collagen implant was performed for uncontrollable glaucoma with deterioration in visual function. Three weeks later, the patient had a rise in intraocular pressure and a scleral ectasia on the sclerectomy. The eye showed an area of scleral ectasia in the bleb as well as iris adhesion. Partial resection of the bleb after iris detachment led to poor anatomic and IOP results. The indications for deep sclerectomy must be carefully considered, especially in patients at a young age with this type of glaucoma.
