The study aims to evaluate spectral domain optical coherence tomography (SD-OCT) features of vitreoretinal lymphoma (VRL). Review of records and SD-OCT images of vitreoretinal lymphoma evaluated at Ocular Oncology Service, Wills Eye Hospital between July 1, 2000, and April 1, 2019.

There were 55 eyes of 32 patients included. At presentation, SD-OCT features included vitreous opacities (n = 36, 65%), preretinal deposits (n = 7, 13%), intraretinal deposits (n = 8, 15%), subretinal deposits (n = 20, 36%), retinal pigment epithelium abnormalities (n = 35, 64%), and subretinal pigment epithelium deposits (n = 35, 64%). Of 36 eyes with observed tumor progression, comparison (initial visit vs. time of progression) revealed more intraretinal deposits (17% vs. 50%, P = 0.005) at progression. Of 15 eyes with tumor recurrence, comparison (initial visit vs. time of recurrence) revealed more intraretinal deposits (7% vs. 47%, P = 0.04) at recurrence. At last visit, 39 eyes demonstrated tumor regression. By comparison (initial presentation vs. regression), there were less frequent vitreous opacities (67% vs. 0%, P < 0.001), intraretinal deposits (15% vs. 0%, P = 0.03), subretinal deposits (36% vs. 0%, P < 0.001), and subretinal pigment epithelium deposits (69% vs. 21%, P < 0.001) at regression.

Using SD-OCT in patients with vitreoretinal lymphoma, local tumor regression correlated with a reduction in vitreous opacities, intraretinal deposits, subretinal deposits, and subretinal pigment epithelium deposits. SD-OCT is useful in judging vitreoretinal lymphoma response to therapy.
