Purpose: To determine the factors that may affect the accuracy of vitrectomy cell block technique in detecting atypical lymphoid cells in patients with vitreoretinal lymphoma (VRL). Methods: We retrospectively reviewed 43 eyes in 39 patients who underwent vitrectomy for definitive histological diagnosis of VRL with vitrectomy cell block technique and/or smear preparation at Kyushu University Hospital from January 2001 to March 2016. The association of detection of atypical lymphoid cells using vitrectomy cell block technique with the following factors was assessed using logistic regression analysis: age at diagnosis, sex, presence or absence of concurrent cataract surgery with vitrectomy, clinical grading of vitreous haze, presence or absence of subretinal tumor infiltration, interval between initial symptoms and vitrectomy, and presence or absence of systemic corticosteroid therapy before vitrectomy. Results: Atypical lymphoid cells were more significantly detected using vitrectomy cell block technique compared to that using smear preparation (p = 0.018). After adjusting for age and sex, concurrent cataract surgery (odds ratio [OR], 10.41; 95% confidence interval [CI], 1.42–76.41) and subretinal tumor infiltration (OR, 5.06; 95% CI, 1.06–24.32) were significantly associated with failure of histological analysis with vitrectomy cell blocks. In multivariable logistic regression analysis, similar results were obtained, although subretinal tumor infiltration was only marginally associated with the detective capability of the technique. Conclusion: Vitrectomy cell block technique significantly improved the definitive diagnosis of VRL. Concurrent cataract surgery with vitrectomy and subretinal tumor infiltration were risk factors for failure in vitrectomy cell blocks.
