IRIS RETRACTION SYNDROME-ASSOCIATED WITH NONRHEGMATOGENOUS RETINAL-DETACHMENT

Purpose: To present the first documentation of iris retraction syndrom e in eyes with nonrhegmatogenous retinal detachment. Patients and Meth ods: One patient with age-related macular degeneration and another wit h panuveitis developed exudative retinal detachment with iris retracti on configuration. Ultrasound biomicroscopy was performed to investigat e the anatomic relationship of structures in the anterior segment of t he eye. Results: Ultrasound biomicroscopy demonstrated a severe backwa rd bowing of the peripheral iris with irido-ciliary body and irido-zon ular contact as well as broad iris lens touch. The iris retraction syn drome resolved after pupil dilation and disruption of the pupillary ad hesions in both cases. The retinal detachment resolved several months later, without surgery. Conclusion: Iris retraction syndrome appears n ot to be exclusive to rhegmatogenous retinal detachment but can presen t in eyes with exudative - nonrhegmatogenous retinal detachment. Thus, when the configuration of the iris shows bowing in patients with reti nal detachment, iris retraction syndrome should be considered and prom pt pupil dilation should be carried out.
