Ultrasound biomicroscopic diagnosis of cyclitic membranes.

Purpose: To evaluate the utility of ultrasound biomicroscopy in imaging cyclitic membranes.

Methods: Patients with hypotony and suspected or known cyclitic membrane underwent ultrasound biomicroscopic examination. Histopathology of cyclitic membrane was correlated with ultrasound biomicroscopy in three cases.

Results: Six eyes of six patients were enrolled. Mean patient age was 62.2 +/- 18.4 (SD) years. The mean intraocular pressure in the affected eye was 4.3 +/- 3.4 mmHg. Three eyes were pseudophakic and three eyes were aphakic. All eyes had undergone two or more previous intraocular surgeries. Ultrasound biomicroscopy imaged the cyclitic membrane in all six eyes. Histopathology revealed fibroproliferative cyclitic membranes with associated inflammatory cells.

Conclusion: Ultrasound biomicroscopy is useful in detecting the presence of those cyclitic membranes that may not be identified on clinical examination.
