Cysts and tumours of the iris: Diagnostic tools and key management considerations-A review

The iris is a unique structure, with exquisite variations in colour and form. Pathological changes, specifically including iris cysts and tumours are relatively uncommon, difficult to diagnose, and yet potentially blinding or life-threatening. Based on a comprehensive literature review, with highly illustrated key case examples, this report aims to guide the clinician in filtering the differential diagnoses of iris cysts and tumours. Evaluation is in the context of key diagnostic clinical tools and management considerations. Diagnostic imaging techniques include serial anterior segment photography, ultrasound, anterior segment optical coherence tomography, and iris fluorescein angiography, however, the roles of computerised topography and magnetic resonance imaging are also considered in this review. Management includes categorisation in terms of solid iris tumours (melanocytic vs. non-melanocytic), or iris cysts (primary vs. secondary) that may be usefully differentiated by clinical assessment, avoiding more invasive interventions. Cystic lesions are generally benign, although implantation cysts in particular cause significant complications and surgical challenges. Most solid tumours are melanocytic and also typically benign. However, in larger lesions, rapid growth, symptoms and complications more likely indicate malignancy, requiring further investigation.

Iris lymphoma-a systematic guide for diagnosis and treatment

Iris lymphomas are rare malignant neoplasms arising either as primary tumors in the iris or as secondary tumors involving the iris. We summarize previously published data and make recommendations for work-up strategies for cases of suspected iris lymphoma. Our objective is to provide a structured overview of the typical clinical symptoms and signs, the pathologic, ophthalmic, as well as hematologic work-up for diagnosis, treatment, and follow-up of iris lymphomas and offer a flowchart on how to diagnose and treat these tumors.
