Iris configuration in accommodation in pigment dispersion syndrome
Balidis MO; Bunce C; Sandy CJ; Wormald RPL; Miller MHEye 2002; 16: 694-700
PURPOSE: This study was conducted in order to investigate the effect of accommodation on the iris morphology and iridolenticular contact, in eyes with Pigment Dispersion Syndrome and Pigmentary Glaucoma, using high-resolution ultrasound. METHODS: The authors performed a prospective observational study, examining a group of 30 pigment dispersion syndrome and pigmentary glaucoma patients (49 eyes) and a smaller group of eight 'normals' non-pigment dispersion syndrome patients (eight eyes). All patients underwent ultrasound biomicroscopy, before and during accommodation. RESULTS: The iris profile before accommodation was found convex in 48.5%, flat in 19.7% and concave in 31.8%. Following accommodation the iris configuration remained unchanged in 66.2%, increased in concavity in 20.3% and decreased in concavity in 13.5%. CONCLUSIONS: The effect of accommodation on iris configuration and accommodation is highly variable. From the authors' experience, the measurement of iris configuration using ultrasound biomicroscopy may not be a useful method of evaluating the effect of different treatments on iris configuration.
