SILICONE FINE-NEEDLE ASPIRATION RETINAL BIOPSY: A Novel Surgical Technique for Vitreoretinal Lymphoma.

ABSTRACT:

Purpose

To describe a 41-gauge silicone fine-needle aspiration biopsy (S-FNAB) technique and assess its value in diagnosing primary vitreoretinal lymphoma (PVRL).

Methods

Retrospective review of seven consecutive patients who underwent vitreous biopsy (VB) and 41-gauge S-FNAB of retinal/subretinal lesions in a single tertiary center between January 2012 and March 2023.

Results

Of seven patients, S-FNAB confirmed the diagnosis of PVRL in six patients. In five of those patients, both VB and retinal/subretinal S-FNAB (performed at the same procedure) yielded positive results, with the retinal thickness at the biopsy site as small as 231 µm. Four of these five patients had one or more previous negative VB. In one patient, S-FNAB yielded positive results despite a negative
