Biopsy techniques and yields in diagnosing primary intraocular lymphoma

Abstract: A review of current biopsy techniques that are used in obtaining specimens from which to make a diagnosis of primary intraocular lymphoma (PIOL) is presented. Methods for obtaining and subsequently testing vitrectomy specimens are discussed. In addition, the yields of external and internal approaches for obtaining chorioretinal tissue, and diagnostic vitrectomies, are reviewed.

“…Should sufficient material be available for examination, investigation of the vitreous specimens for rearrangements of the immunoglobulin heavy chain gene using PCR provides further evidence of the neoplastic nature of the lymphocytic infiltrate in retinal lymphoma. 17,18,20,22,25,35,49,51 Biochemical analysis of the vitreous specimen for interleukin ratios (IL10 : IL6) may also support the diagnosis of retinal lymphoma. [52][53][54] If possible, retinal lymphoma should be distinguished from other types of intraocular lymphoma, namely primary uveal lymphoma and secondary (metastatic) intraocular lymphoma.…”

“…It is well known that lymphoma cells removed from the vitreous are liable to rapid degeneration unless fixed or exposed to tissue culture medium in a timely manner. 3,4,8 In this study, the core vitreous biopsy and PPV were performed and fixed by the same surgeon and the specimens handled by the same biomedical scientist in the histopathology lab according to standard operating protocols. No tissue was lost during the transport and handling of the fluids.…”

“…One is a vitreous biopsy that targets the core vitreous (1-2 ml obtained) and the other is a formal diagnostic pars plana vitrectomy (PPV) that samples the core and the cortical vitreous, resulting in a larger volume of fluid (50-100 ml), collected in a vitrectomy cassette/bag comprising the dispersed vitreous gel and balanced salt solution (BSS). 3 Although investigators have focused on stopping steroid treatment temporarily to enhance cell viability, prompt processing of the sample, use of tissue culture medium and the use of cytokine assay and PCR for monoclonal testing to improve the diagnostic yield in cases of suspected intraocular lymphoma, 3,4 one simple observation has been overlooked in our experience. In our institution, careful clinical observations have noted a differential distribution of vitreous cells in patients presenting with vitreous cellular infiltrates.…”
