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.
Insights
Ultrasound biomicroscopy (UBM) detected cyclitic membranes in over half of pars planitis patients at diagnosis and follow-up. This imaging technique aids in early detection of these membranes and associated complications.
Area of Science:
- Ophthalmology
- Medical Imaging
- Inflammatory Eye Diseases
Background:
- Previous studies utilized ultrasound biomicroscopy (UBM) for analyzing cyclitic membranes in pars planitis.
- Limited data exists on the prevalence of cyclitic membranes and associated complications at diagnosis and during follow-up.
Purpose of the Study:
- To characterize cyclitic membranes and their complications using UBM in pars planitis patients.
- To evaluate the utility of a 50-MHz linear probe with AVISO-S™ equipment for this analysis.
Main Methods:
- Retrospective review of UBM images from pars planitis patients.
- Data collected from the Inflammatory Eye Disease Clinic in Mexico City between January 2010 and June 2016.
Main Results:
- Cyclitic membranes were present in 56.7% of eyes at initial diagnosis and 68.62% during follow-up.
- Membrane extension involved one to two quadrants in 82.71% of affected eyes.
- Complications included ciliary body detachments (12.35%) and peripheral retinal traction (9.88%).
Conclusions:
- UBM is a valuable diagnostic tool for cyclitic membranes in pars planitis patients.
- It facilitates early detection of these membranes and associated complications during clinical management.
