MORPHOLOGY OF THE ANTERIOR CHAMBER ANGLE IN CONGENITAL GLAUCOMA AFTER GLAUCOMA SURGERY
B. F.Engels, T. S.Dietlein, P. C.Jacobi
Background: In patients with cong. glaucoma the assessment of the anterior chamber angle might be difficult owing to scarring and opacities of the cornea. We tried to differentiate morphological changes following previous glaucoma surgery.
Methods: In eighteen children and young persons (age 0-18 years) with cong. glaucoma and earlier glaucoma surgeries we performed an Ultrasound-biomicroscopy. Previous surgery included goniotomy, trabeculectomy, cyclodialyse, deep sclerectomy and combined strategies.
Results: Following goniotomy or trabeculectomy we found a deepening of the anterior peripheral chamber angle with areas in accordance to scar formation. Most eyes which had undergone trabeculectomy revealed iris at the trabeculectomy cleft.
Discussion: The Ultrasound-biomicroscopy is a method which allows evaluation despite hazy cornea and helps to identify areas of previous glaucoma surgery.
