Aims: To develop a minimally invasive, maximally effective method to biopsy an terior segment tumours. Methods: A 25 gauge aspiration cutter (vitrector) was us ed to biopsy anterior segment tumours. The probe was introduced under sodium hya luronate 1%and through a 1 mm incision. Aspiration (600 mm Hg) cutting (300 cpm ) was performed to obtain specimens for cytology and histopathology. Results: Di agnostic material was obtained in nine of 10 (90%) cases. Diagnoses included ir is naevus, iris stroma, malignant melanoma, melanocytoma, epithelial inclusion c yst, and sarcoid granuloma. All corneal wounds were self sealing. One patient de veloped a transient postoperative increase in intraocular pressure. Within the f ollow up of this study, no patients suffered intraocular haemorrhage, infection, cataract or vision loss. Conclusion: The Finger iridectomy technique was a mini mally invasive and very effective biopsy technique. Aspiration cutting yielded r elatively large pieces of tissue (and cells) used for cytopathological and histo pathological evaluation. Small incision surgery allowed for rapid rehabilitation and no significant complications.
