Use of a special device for the treatment of overfiltration after glaucoma filtering surgery.

Abstract

standardized A and B scan echography were used to look for the possible presence of ciliochoroidal detachment in patients with flat anterior chamber following glaucoma filtering surgery. For this purpose, a scleral shell filled with saline solution was inserted between the lids. As a deepening of the anterior chamber was found in some patients, we planned to utilize these devices for the treatment of flat anterior chambers after glaucoma filtering surgery. 16 patients with flat anterior chambers after glaucoma filtering surgery underwent the insertion of a scleral shell filled with saline solution between the lids. The shell was left in place for 15 min. In all of our patients a deepening of the anterior chamber was achieved. In 5 patients 1 application, in 6 patients 2 applications, in 4 patients 3 applications were needed. The advantages of using this procedures are: the procedure is quick; it does not disturb the corneal epithelium; it is cheap; it does not require suturing the conjunctiva; it can be part of the examination of the anterior segment with echography to look for any ciliary body detachment.
