The Finger iridectomy technique: small incision biopsy of anterior segment tumours

摘要: Aims: To develop a minimally invasive, maximally effective method to biopsy anterior segment tumours. Methods: A 25 gauge aspiration cutter (vitrector) was used The probe introduced under sodium hyaluronate 1% and through 1 mm incision. Aspiration (600 mm Hg) cutting (300 cpm) performed obtain specimens for cytology histopathology. Results: Diagnostic material obtained in nine of 10 (90%) cases. Diagnoses included iris naevus, stroma, malignant melanoma, melanocytoma, epithelial inclusion cyst, sarcoid granuloma. All corneal wounds were self sealing. One patient developed transient postoperative increase intraocular pressure. Within the follow up this study, no patients suffered haemorrhage, infection, cataract or vision loss. Conclusion: Finger iridectomy technique invasive very technique. yielded relatively large pieces tissue (and cells) cytopathological histopathological evaluation. Small incision surgery allowed rapid rehabilitation significant complications.
