Micro-incision, trans-iridal aspiration cutter biopsy for ciliary body tumours.
    Canadian journal of ophthalmology. Journal canadien d'ophtalmologie, 2021, Volume: 56, Issue:2

    To perform micro-incision, trans-iridal, aspiration-cutter-assisted biopsy for ciliary body tumours.. Retrospective, nonrandomized, observational, interventional case series.. Five consecutive patients undergoing ciliary body tumour biopsy were clinically diagnosed using slit-lamp photography, gonioscopy, high-frequency ultrasound imaging, and systemic radiographic staging. A 1-2 mm clear cornea incision was placed opposite to the central clock hour of the ciliary body tumour. Viscoelastic was infused into the anterior chamber for stabilization and endothelial protection. Then, a 27-gauge aspiration cutter was used to make an iridotomy at the iris root and then extend through the iris into the tumour. Biopsy was performed using mechanical cutting starting at 300 cuts per minute and aspiration at 600 mm Hg. After withdrawal of the cutter from the eye, the effluent tube was flushed into a 3 cc syringe, inspected for specimen under the operating microscope and sent for pathology. Multiple biopsies were performed on each patient. Viscoelastic was removed and Seidel examination of the corneal wound performed.. Five eyes were biopsied. A mean 3.6 passes were used to obtain tumour tissue. Tumour cells and tissue were obtained in all cases. Cytologic, histopathologic, and immuno-histochemical analysis were performed (100%, n = 5/5). Diagnoses included melanoma (60%, n = 3/5), melanocytoma (20%, n = 1/5), and leiomyoma (20%, n = 1/5). Transient postoperative hyphemas cleared within 1 week (80%, n = 4/5). No secondary glaucoma, infection, or cataracts were noted.. Aspiration-cutter biopsy through the iris root provided a minimally invasive, safe method for obtaining ciliary body tissue for cytology, histopathology, and immunohistochemical analysis.
