Abstract

Background: In previous studies, authors use ultrasound biomicroscopy (UBM) to analyze the characteristics of cyclitic membranes and the associated complications in patients with pars planitis. However, there are no reports regarding the prevalence of cyclitic membranes or complications at diagnosis and during follow-up.

Purpose: To describe the characteristics and complications of cyclitic membranes, as determined by UBM in patients with pars planitis using AVISO-S™ (Quantel Medical) equipment with a 50-MHz linear probe with a focus at the pars plana.

Design: This retrospective study reviewed UBM images of patients diagnosed with pars planitis, from the Inflammatory Eye Disease Clinic in Mexico City from January 2010 to June 2016.

Results: Cyclitic membranes were observed in the first UBM image in 67 eyes (56.7%) and during follow-up in 81 eyes (68.62%). In 67 eyes (82.71%), the cyclitic membranes extended through one or two quadrants. Extension toward the posterior lens capsule was recognized in 15 eyes (18.52%) and extension toward the peripheral retina in 12 eyes (14.81%). Complications included ciliary body detachments in 10 eyes (12.35%) and peripheral retinal traction in 8 eyes (9.88%).

Conclusions: UBM is a valuable tool for the diagnosis of cyclitic membranes at admittance and during follow-up of patients with pars planitis; it helps the clinician to detect this complication early.

Keywords: Cyclitic membrane; Pars plana; Pars planitis; Ultrasound biomicroscopy; Uveitis.
