Iris Cyst

Iris cyst is a cystic lesion of the iris, classified as primary (stromal/serous), secondary (implantation after surgery/trauma), or parasitic (echinococcus). Most are asymptomatic incidental findings; larger cysts may cause distortion, secondary glaucoma, or iritis. Treatment: observation with serial imaging for asymptomatic; laser ablation or surgical excision for progressive/symptomatic cysts; treat parasitic cause.

Common Symptoms

Causes and Pathogenesis

Primary stromal cyst, implantation epithelium after trauma/surgery, or parasite forms an iris cyst.

Treatment

Observation if asymptomatic; laser ablation/excision if progressive; treat parasitic cause

Preventive Measures

Serial imaging; treat parasitic disease.
