Purpose: Intravascular large B-cell lymphoma (IVLBCL) is an extremely rare, aggressive, multi-system disease that can affect the eye. We describe the ophthalmic presentation, multimodal imaging and treatment response of uveal IVLBCL.
Methods: Review and case report.
Results: Twenty-five published cases of IVLBCL involving the eye including our own were identified. Of these, 15 patients (60%) had clinically-detectable intraocular involvement, 6 (24%) had extraocular ophthalmic involvement only and 4 (16%) had subclinical, undiagnosed intraocular involvement that was retrospectively detected on post-mortem ocular histopathology. The male to female ratio was 1.08:1 with a mean presenting age of 65.1 ± 11.7 years (range 38-82 years). The majority of cases had bilateral involvement (21/25 patients, 84%). Extraocular manifestations included diplopia, ptosis and ophthalmoplegia. Intraocular manifestations included serous retinal detachment (13/28, 46%), retinal hemorrhages (9/28, 32%), vascular changes (9/28, 32%), retinal pigment epithelial changes (7/28, 25%), thickened choroid (6/28, 21%), vitritis (5/28, 17%), cotton-wool spots (3/28, 10%), and a subretinal lesion (1/28, 3%). Histopathological diagnosis was most commonly confirmed on post-mortem enucleation (8/25 patients, 32%), skin (6/25 patients, 24%) or brain biopsy (6/25 patients, 24%).
Conclusion: The presence of intra-retinal hemorrhages, cotton wool spots and/or Roth spots help differentiate IVLBCL from other similarly presenting diseases such as central serous chorioretinopathy and Vogt-Koyanagi-Harada disease. New signs not previously described in IVLBCL include macular bacillary layer detachment and hypo-cyanescent spots on ultra-wide field indocyanine green angiography. The diagnosis is elusive and requires tissue biopsy, but systemic chemotherapy and rituximab can lead to rapid improvement of the eye.
