Use of a special device for the treatment of overfiltration after glaucoma filtering surgery
Background:
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.
Methods:
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.
Results:
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.
Conclusions:
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.
