Chorioretinal biopsy in the diagnosis of intraocular lymphoma: a case report

A patient with non-Hodgkin lymphoma with low grade malignancy complained of gradual visual loss. Symmetric multiple deep retinal yellow dots were disseminated in both fundi. The patient developed progressive papilledema associated with further decreasing visual acuity. Other signs of uveitis were absent. A chorioretinal biopsy confirmed the intraocular lymphomatous involvement. Cerebrospinal fluid revealed abnormal lymphocytes and local Ig-M production thus proving the lymphomatous meningeal involvement.
