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.
Insights
Ultrasound biomicroscopy effectively images cyclitic membranes in eyes with hypotony. This imaging technique aids in detecting these membranes when clinical examination is insufficient.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Cyclitic membranes can cause hypotony and vision loss.
- Diagnosis can be challenging, especially when not visible on clinical examination.
Purpose of the Study:
- To assess the effectiveness of ultrasound biomicroscopy (UBM) for imaging cyclitic membranes.
- To determine the utility of UBM in cases of ocular hypotony.
Main Methods:
- Ultrasound biomicroscopy was performed on six eyes with suspected or known cyclitic membranes and hypotony.
- Histopathological correlation was obtained in three cases.
- Patient demographics and intraocular pressure were recorded.
Main Results:
- UBM successfully visualized cyclitic membranes in all six evaluated eyes.
- Patients were elderly (mean age 62.2 years) with low intraocular pressure (mean 4.3 mmHg).
- Histopathology confirmed fibroproliferative membranes with inflammation.
Conclusions:
- Ultrasound biomicroscopy is a valuable tool for detecting cyclitic membranes.
- UBM can identify membranes not apparent through standard clinical examination, aiding diagnosis in hypotonic eyes.
