Summary
High-frequency ultrasound is crucial for diagnosing and managing anterior segment tumors, aiding in treatment planning. This imaging technique helps identify various tumors and assess their extent for effective patient care.
Area of Science:
- Ophthalmology
- Medical Imaging
- Oncology
Background:
- Anterior segment tumors encompass a range of conditions, including primary neuroepithelial cysts, uveal melanomas, and metastatic tumors.
- Accurate diagnosis often relies on clinical history and ocular examination, but advanced imaging is essential for detailed assessment.
Purpose of the Study:
- To review the diagnostic and therapeutic applications of high-frequency ultrasonography in anterior segment tumors.
- To provide an overview of current clinical practices for managing these ocular conditions.
Main Methods:
- Utilizing clinical history and ocular examination for initial diagnosis.
- Employing low and high-frequency ultrasound for tumor assessment, extension, and involvement of surrounding structures.
- Considering fluorescein angiography, computerized tomography, and fine-needle aspiration biopsy in specific cases.
Main Results:
- High-frequency ultrasound is indispensable for determining tumor extension and involvement.
- It aids in diagnosing small ciliary body melanomas and iris pigment epithelial cysts.
- Ultrasound measurements are vital for planning plaque radiation therapy.
Conclusions:
- High-frequency ultrasonography plays a unique and critical role in the diagnosis and treatment of anterior segment tumors.
- Treatment decisions are guided by tumor characteristics, with options ranging from observation to local resection, radiation, and enucleation.
- This review highlights the importance of ultrasonography in optimizing patient management and outcomes.
