Iris Cyst

Excerpt

Iris cysts are rare ocular anomalies characterized by fluid-filled sacs within the iris. Although the exact cause of iris cysts remains unclear, they are often congenital or linked to trauma or inflammation. Iris cysts can vary in size, shape, and location within the iris. Although most iris cysts are typically benign and asymptomatic, they pose diagnostic and management challenges, leading to visual disturbances, increased intraocular pressure, or discomfort. A careful differential diagnosis is essential to distinguish iris cysts from other conditions, such as iris melanomas, which can be malignant.

Iris cysts are usually identified during routine eye examinations using diverse imaging techniques such as slit-lamp biomicroscopy, ultrasound biomicroscopy (UBM), or optical coherence tomography to assess their characteristics. Treatment strategies for iris cysts depend on their size and impact on visual function. Asymptomatic cysts may undergo monitoring, while symptomatic ones may require management with medications, such as atropine, or surgical interventions, including cyst aspiration, laser therapy, or excision. Regular follow-up appointments are essential to monitor any changes in the cyst's size or characteristics. Early detection and prompt management are crucial to preserve ocular health and avert potential complications.
