FINE-NEEDLE ASPIRATION BIOPSY OF ORBITAL AND EYELID LESIONS

Thirty-five patients with orbital and eyelid lesions were subjected to fine needle aspiration biopsy (FNAB). Histopathology or other investi gations were available in 18 cases; in 17 cases (94%) a concordant dia gnosis was reached. There was one false-positive diagnosis in 18 cases (5.5%). FNAB is a reliable and safe diagnostic technique and can be u sed routinely in outpatient departments for the diagnosis of orbital l esions. It is particularly useful in nonresectable and retrobulbar orb ital lesions.
